Guards must be provided on all chain and sprocket installations in accordance withprovisions of ANSI/ASME B15. 1-1984
“Safety Standards for Mechanical Power Transmission Apparatus”,and ANSI/ASME B20.1-1990” Safety
Standards for Conveyors and Related Equipment, or other applicable safety standards.When revisions of these standards are published, the updated edition shall apply.
Always lock out the power switch before installing, removing, lubricating or servicing achain system.
When connecting or disconnecting chain
a. Eye protection is required. Wear safety glasses, protective clothing, gloves and safety shoes.
b. Support the chain to prevent uncontrolled movement of chain and parts.c. Use of pressing equipment is recommended. Tools must be in good condition and
correctly used.d. Determine correct direction for pin/rivet removal or insertion.
WARNINGUse care to prevent injury. Comply with the following toavoid serious personal injury.
CAUTIONWe take great care in manufacturing the chains, sprockets and other products described here. Nevertheless, errors or shortcomings in selection, handling and maintenance can cause major accidents,including chain breakage and conveyor damage.Refer to the relevant design documents, selection criteria, instructionmanuals and other before using them. If any points are unclear, please contact the manufacturer for clarification.

Maintain Equipment Properly
Storage of conveyor chains and sprockets
Conveyor chains may break due to uneven loading and wear caused by poor alignment ofequipment or changes over time. Make sure the chain is attached correctly.
Do not subject the conveyor chain to direct impact, or to direct heating by blowtorch etc. Suchtreatment will greatly reduce chain performance and could cause the chain to break.
Re-machining chains and sprockets is dangerous. Never electroplate heat-treated chains orsprockets, as it can cause hydrogen embrittlement fracture. Never weld heat-treatment chainsor sprockets, as heat effects can reduce strength, causing the chain to break. After using ablowtorch or other heat source to heat or cut a chain, be sure to remove all components oneither side of the heated area that may have been affected by the heat.
Safety covers etc. must be installed to make sure nobody can touch equipment while it is inoperation.
If any foreign body etc. gets tangled in the conveyor chain while it is in motion, the chain mayslip off the sprocket or, in some cases break.
Make sure the main power supply is switched off before starting maintenance and inspectionworkmand take precautions to prevent anyone from switching it on by mistake.
The lifespan of a conveyor chain varies enormously depending in whether it receives propermaintenance and lubrication, Wear extension can cause the chain to ride off the sprocket, or tobreak, so practice appropriate maintenance and lubrication.
Conveyor chains and sprockets are consumable parts, As such, they require proper periodicmaintenance and replacement. Avoid replacing only part of a chain. Replace the chain as awhole.
Handle chains sprockets as mechanical components, Do not throw or drop them whenunpacking them, and store them away from rain, condensation, dust etc.
Conveyor chains may break when an excessive load is placed on them. Be sure to use anychain only within its proper load capacity, based on an understanding of its structure andspecifications.
Use of conveyor chains in alkaline or acidic surroundings can cause brittle fracture so be sureto select a chain appropriate for the conditions in which it will be used.
The performance of conveyor chains declines at high and low temperatures, possibly causingthem to break in some situations, so be sure to select the right chain for the conditions.

Can be used for a wide variety of applications.
The chain is self-lubricating, light weight, low noise and has a lowcoefficient of friction. This chain has a very long life, while requiringno lubrication.
The composition of R and F rollers is altered, increasing the wearlife between the bushing and roller allowing a higher allowable rollerload.
Approximately two times tensile strength of the standard series withmuch higher roller load capacity.
Wear resistance between pin and bushing is improved using aspecial heat-treating process.
For use where high tensile strength is required without addedweight. Tensile strength approximately. Two times as strong as thatof the CT Series.
With a low coefficient of friction and high allowable roller load, achain two sizes smaller may be used.
For use with equipment for which where even slight elongation isunacceptable. Assures smooth movement and accuratepositioning.
For use in sanitary environments where high temperatures arepresent. Long life. Avoid alkali environments.
Self-lubricating, low coefficient of friction, low noise, lightwightand anti-corrosive. Avoid alkali environments
WIth a tensile strength 1.6 times as strong as that of the NT Series,it is useful where a lgihtweight, strong chain is required.
For high temperature, strictly sanitary environments, and for rustprevention.
Self-lubricating, low coefficient of friction, low-noise, lgithweightand highly anti-corrosive with a long life that is completely free ofoil.
Increased wear resistance between bushing and roller, tolerance ofslightly wet conditions.
Self-lubricating, low coefficient of friction, low-noise, lgithweightfor use in sanitary environments with slight wet conditions.

1) Wide SelectionThousands of combinations of steel materials and specifications of component parts are available inaddition to standized chain specifications.
2) Quick DeliveryRF Conveyor Chains, even if made of special alloy steels, are standardized in the respective stages fromdesign to production and are always carried in stock in large quantity to ensure quick delivery.
3) High QualityRF Standard Conveyor Chains have uniform and high quality based on our ever improving productiontechnology and standardization. This high quality gives longer life and reduced maintenance costs.
Link PlatesLink plates are the component partsreceiving chain tension. The holes forpress-fitted pins or bushing areaccurately punched to maintainuniform pitch.
RollersRollers are free to rotate over the bushings. When the chain engages withthe sprocket, rollers work as bearings and serve to reduce shock and wear.When the chain is running on rails or wear strips, the rollers reduce runningfriction on the chain.
PinsPins are made to exact specifications for high strength, sturdinessand wear resistance, then rigidly press-fitted to the link plate. Pinsresist shearing force through chain tension and rotate in the bushings,providing bearing surfaces when the chain articulates over a sprocket.
BushingsBushings are made to obtain highwear resistance then press-fitted tothe roller link plates, providing abearing surface for pin rotation.
Attachment LinksAttachments are provided when necessary
for fixing attachments to the chain.

Easy detachable T-pins are used on every pin tofacilitate easy disconnection at the required link.Connecting links are not necessary.
11Korea Conveyor Ind. Co., Ltd.
R RollersOutside diameteer of roller is larger than theheight of the link plate, so the chain can roll onthe guide rail. R Rollers are suitable for carryinglarge and heavy materials.
S, M and N RollersThe outside diameters of the S, M and N rollersare less than the height of the link plate and arespecified depending on the application. The MRoller is a litter larger than the S Roller, but thesame size as the N Roller. For chains with the NRoller, the pin diameter is a little larger than thatof the M Roller chain.
F RollersFlanged rollers serve to retain the chain on therails. F Rollers are also suitable for carrying largeand heavy materials.
Various types of chain attachments can beprovided according to the application and thesize and shape of the material to be conveyed.Some of them are standardized with the A, K, SKand G Attachments. For details and dimensions,see page 176a-178a. Attachments can beassembled at any required spacing.
K AttachmentK Attachment : bent type link plate on both sides. K-1, K-2, or K-3 indicates K Attachment with one, two or three holes, respectively.
A AttachmentA Attachment : bent type link plate on one side only. A-1, A-2, or A-3 indicates A Attachment with one, two or three, holes, respectively.

There is no stick slipping with TSUBAKI Bearing Roller Conveyor Chains.Use this chain in applications where stick slipping cannot be toleerated.
Prevention of Stick Slipping. 4
Backed up by over 36 years chain manufacturing experience and advanced production technology, KoreaConveyor is able to offer a revolutionary new kind of chain for conveying applications - the KoreaConveyor Bearing Roller Conveyor Chain.
THis recently developed conveyor chain incorporates finely machined cylindrical roller bearings. The resultis less friction, higher maximum allowable load, and a reduced need for lubrication and maintenance.

Korea Conveyor Bearing Roller Conveyor Chains
Compact and High Performance1
Use of cylindrical roller bearing inside the chain rollers lowers frictionalforces and reduces the need for lubrication and maintenance by 5-10times (depending on the application) compared to conventionallyconstructed conveyor chains. The result is a chain with an increased lifeand almost no required maintenance.
Virtually Maintenance Free & Long Chain Life2
Small pitch to large, heavy duty sizes of TSUBAKI Bearing Roller ConveyorChains are readily, available in a range of specifications and can bedelivered quickly upon receipt of your order.

The base chain consists of outer link plates, inner link plates,
and pins. Attachments can be welded onto the base chain.
Special alloy steel provides greater tensile strength and the
chain’s simple construction provides greater allowable wear.Consequently, these chains are ideal for conveying material
that is very abrasive, wet or hot.

NFX Block Chains for Flow Conveyors
23Korea Conveyor Ind. Co., Ltd.
These chains are based on the S roller type of Korea Conveyor RF Standard Conveyor Chain. The pins of which are
extended to hold flanged outboard rollers on both sides, the sprockets drive the chain by engaging the S rollers at the
chain center. The outdboard rollers are for running and supporting the load.
When ordering, specify the series name (DT-Basic, AT or BT) and the required spacing of the outboard rollers.)
1. Installing special attachments such as pushers or tilting dogs.
2. Supporting heavier loads. 3. Installing guides for return strand of chain since special attachments interfere with the return guide.
Note : For average tensile strength, refer to the table on page 8.

These chains are based on RF Conveyor Chain. Extra rollers are mounted on top of thechain pitch line in the middle of each link to directly support conveyed materials.
When ordering, specify the following :
1. Series name such as DT (Basic), AT or BT. 2. Spacing of top rollers. Top rollers spaced every even number of links are usually furnished on the inner link unless otherwise specified. Special sprockets are required for this chain, since the standard sprocket for RF Conveyor Chain interferes with the top roller.
Applications1. Stopping material while chain is running (see Fig. 1)2. Smoother transfer of material from conveyor to conveyor where conveyor speeds are considerably different (see Fig. 2)
Note : For average tensile strength, refer to the table on page 12. * No bending portion at pin link plate.

These chains consist of outer link plates, inner block links andpins. They have excellent rigidity with greater tensile strength. Keychain components are made of heat-treated steel for higher wearresistance. These chains are usually used as shown on the right.
Applications1. Pushing trucks2. Conveying hot material on chain3. Drawbench usage
The style of pusher dog is determined by theshape of the conveyed material and theapplication. The spacing of pusher dogs isdetermined by the conveyor capacity and thesize of the conveyed material. The following types of dog attachments arecommonly used:
1. Solid pusherInner or outer pusher link to push material.
2. Tilting dogWhen material on the conveyor runs relativelyfaster than the chain, the dog is pushed downfrom behind to enable material to pass over. Thedog then springs back to resume its originalposition.
3. Ducking dogThe dog is supported on the guide rail to conveymaterial. When the guide rail is interrupted, thedog ducks down, leaves the material and passesbeneath it.
4. Tilting and ducking dogBoth tilting and ducking functions arecombined. When the dog comes in contact withthe table surface, it lets the material pass over.When the guide rail is discontinued, the dogleaves the material and passes beneath it.

Outstanding FeaturesElevator Chain & Bucket
Bushed Roller Chain
The bushed roller chain is made of a special alloy steel, whichhas a high resistance to shock loads resulting in low sprocketwear.
As indicated in the diagram on the right, the link plate has aunique shape which permits buckets to be bolted directly to thechain firmly.
High Speed Chain (for the NBH Type only)
In the past, the 45 m/min limit on the speed of the elevator chainhas meant that to increase conveying capacity, larger elevators hadto be selected. After many years of development and testing of highspeed chains, we have produced the revolutinary 90 m/min NBHType bucket elevator. The high speed of this elevator allows largevolumes to be handled with compact casings.
The chain has a shorter pitch and superior construction to reducethe impact and noise caused by high speed operation. Then chainis constructed from a special wear and fatigue resistant steelmaking the NBH Type a reliable high speed bucket elevator.

If chain and sprocket do not match the chain will not run smoothly, and bothchain and sprocket will have to be replaced more frequently. The necessary conditions for sprocket are as follows :
1. The form and pitch of the teeth must be precise and uniform. 2. Wear resistance must be adequate. 3. The structure must be sturdy, with adequate shock resistance.
Tooth design criteria
P.C.D. = P X
O.D. = P.C.D. + 0.7 d
V = 2d When d � h
= 3d When d � h
(However, P-V≧5mm must be satisfied)
D = d + 2 (d ≦ 50)
= d + 3 (50 � d ≦ 100)
= d + 4 (100 � d)

F = 0.6 d
t = 0.75W ~ 0.85W
G = + or to = 0.5 t

Sprockets for Standard Conveyor Chains
Note
The method here for calculating boss diameter and boss width is
a simplified approach. For a more detailed approach, use
standard mechanical design.
Boss diameter and width
The boss diameter and boss width for standardsprockets are as shown in the table below, but insome cases the conditions of use or constraintsimposed by the installation location may require aspecial design. The following is a summary ofhow to find the bess diameter and width.

This type of chain provides solid contact between the chain and material to be conveyed. Due toroller rotation over the chain guide rail less friction is provided.
Applications
1. Conveyor lines of thick plate or section steel in steel mills2. Automobile or container assembly lines
RFD Deep Link Chains
71Korea Conveyor Ind. Co., Ltd.
These chains consist of outer link plates, inner block links andpins. They have excellent rigidity with greater tensile strength. Keychain components are made of heat-treated steel for higher wearresistance. These chains are usually used as shown on the right.
Applications1. Pushing trucks2. Conveying hot material on chain3. Drawbench usage
The style of pusher dog is determined by theshape of the conveyed material and theapplication. The spacing of pusher dogs isdetermined by the conveyor capacity and thesize of the conveyed material. The following types of dog attachments arecommonly used:
1. Solid pusherInner or outer pusher link to push material.
2. Tilting dogWhen material on the conveyor runs relativelyfaster than the chain, the dog is pushed downfrom behind to enable material to pass over. Thedog then springs back to resume its originalposition.
3. Ducking dogThe dog is supported on the guide rail to conveymaterial. When the guide rail is interrupted, thedog ducks down, leaves the material and passesbeneath it.
4. Tilting and ducking dogBoth tilting and ducking functions arecombined. When the dog comes in contact withthe table surface, it lets the material pass over.When the guide rail is discontinued, the dogleaves the material and passes beneath it.

A flat top type chain is designed to carry very heavy loads such as steel coils produced by hot rolling orcold rolling in an ironworks or steel mill. Based on a standard conveyor chain, the top face of the chainallows stable conveyance of heavy coils.Since a large load acts on the chain, a heavy-duty construction is adopted. We manufacture 16 kindsof standard chains.
The chain features bearings built into the rollers to minimize running resistance, and is available as typeand maintenance-free non-lubrication type.
Flat Top type Chain for Coil Conveyor
The value marked ※ of non-lubrication type is O.
73Korea Conveyor Ind. Co., Ltd.
This is coil conveying system that assumes the principal role in handing coils.
With achievements in research and development on machine configuration and operating
techniques of conveying systems, Korea Conveyor will convey your coils safely
and positively while maintaining coil quality. Walking beams will also be ideal for coil entry and
derivery near the mills where the conveying is short.
Although hydraulic cylinders were used in the past for the walking beam, theuse of a linear actuator (power cylinder) is contributing greatly to savings inenergy and maintenance.
Car conveyors with buffer function are ideal for thecoil storage line between processes.

When selecting the type of conveyor chain, it is necessary to identify the physical properties of the materialsconveyed. Then, the conveying method and the type of chain conveyor should be determind, consideringcost performance. Three basic types of conveyor are shown on page 6, which can be used for detemining thetype of conveyor chain.
KKeeyy PPooiinnttss iinn DDeetteerrmmiinniinngg tthhee TTyyppee ooff CCoonnvveeyyoorr CChhaaiinn❶ To reduce the running resistance of the conveyor chain when conveying material, a Loading Type Conveyor is adopted. Energy saving can be achieved with this conveyor.
❷ Powdery or dusty material should be conveyed in a sealed casing such as with Flow Conveyor.❸When material conveyed is very abrasive, the conveyer should be designed to prevent the material from directly contacting the conveyor chain. lf this cannot be done, the chain speed should be reduced as much as possible.
❹ For very corrosive materials or atmospheres, suitable specifications for the conveyor chain should beselected. Please refer to Table 13.
The most suitable type of roller should be selected according to the requirements of the application.
Remarks
Type
•Lower cost
•For light conveyor
•Vertical conveyor
•Shorter center distance
•Lateral movement to be avoided
•Long center distance
•Less friction
•Most basic type
•Less friction
•For large and heavy materials
•Long center distance
1) A catenary is made on the drive sprocket side
Tension of the catenary makes chain-sprocket engagement smooth. Lubrication at the catenary is effective.
2) No guide on return side
For short center distance and slow chain speed. The mass ofthe chain on the return side may cause vibration and thisaffects chain operation.
3) To support the chain on return side by guide or roller.
Contact between chain and guide or roller mayenhance wear of chain or damage chain as chainarticulates at the roller or guide. This may also causevibration and affect chain operation.In case of a long center distance, it is practical to dividethe return side into several catenaries.Catenary sag can absorb chain elongation/shrinkage byheat, etc. This arrangement can be used when chainspeed is comparatively slow and the catenary sagshould be about 10 percent of free span. This cannotbe recommended for reverse drive.

❶Smoother chain operation can be expected as the number of sprocket teeth increases. This means that for a sprocket with the same outer diameter, a shorter pitch chain can operate more smoothly due to a reduction in the polygonal speed fluctuation or less articulating angle of chain on the sprocket. This also results in less wear between pin & bushing.
❷ Longer pitch chain, though more expensive per link would be cheaper for a unit length of chain in general. Chain pitch for Unit Conveyor is determined by unit size or attachment spacing.(Example) •Attachment spacing = 2m
•Chain pitch = 100, 200, 250•Chain pitch can be selected by dividing attachment spacing by an even number.
❸ The chain pitch for Bulk Conveyor is determined not only by materialitself, but also by conveyor capacity.Conveyor capacity is determined by conveyor capacity. Conveyor capacity is determined by sizes of bucket, apron, scraper, etc. Chain pitch is in turn determined by these sizes.
❹ Space limitation should also be kept in mind when selecting sprocket.❺Chain pitch relates to the number of sprocket teeth and chain speed shown in Table 2.
Please refer to pages 16~18.

Multiply tension TMAX calculated with formulas in Table 3 by Safety Factors in TableTable 8 For required strength, and then select chain which satisfies the strengh.
Notes
❶When there are any regulations, guidelines, etc. effecting selection, select chain bassd on the regulation and the Safety Factor Selection explained in this page. Then take the larger or stronger chain.
❷When a conveyor consists of multiple strands of chain, correct the number of strands in the above formula to allow for uneven load to the chain.
❸ In the following applications. chain life is reduced to 1/2-1/10. Determine safety factor referring to clause 14.
Considerations for special environments 1. Short distance transportation of havy load2. Exposure of chain to abrasive, adhesive and corrosive materal 3. High temperature environments4. High humidity5. No lubrication

Korea Conveyor Engineering Information
Special environments mean the following conditions•high temperature•low temperature•high humidity•high chemical reactionsCombinations of the above conditions often exist where chain is used. Therefore, to achievesatisfactory chain life, it is important to select adequate material.
14. 1 At Low Temperatures
When chain is used at low temperatures, the following should be considered.❶ Low temperature brittleness of material. In general, steel materials become brittle at low temperatures depending on chemical composition, etc. RF Conveyor Chain should not be used at temperatures lower than those specified in Table 12.
❷ Freezing of chain
Freezing between pin and bushing, inner and outer linkplates, or bushing and roller will cause anexcessive load on chain and drive unit. Freezing should be avoided by generally filling gapsbetween parts with lubricant which does not freeze at the temperapture the chain is used in. For thispurpose, silicon grease is recommended.
14.2 At High Temperatures Over 400
Strength of chain decreases as temperature of chain increases by being heated up by the heat ofmaterial conveyed or environment. Limits to use of each chain are determined by temperature ofchain and material. For Safety Factor at temperature up to 400℃…, please consult with KoreaConveyor.
Points Concerning Heated Chain(1) Friction factor gets larger than usual.(2) There is a possibility to cause heat fatigue when different materials have been welded, due to the difference of heat expansion coefficient.
(3) In environments at temperatures over 400℃ expansion and clearance are to be considered.(4) Creep breakage(5) High temperature brittleness(6) Carbide precipitation brittleness(7) Effect of fluctuating temperatures (cooling and expansion)
Points Concerning Lubricant(1) Heat resistance of silicon, graphite and molybedenum disulphide oil are superior.

Table 13: Anticorrosiveness to Various Kinds of Solvent
When selecting chain, please check whether or notmaterial is fully anticorrosive by referring to this table.This table shows properties of material at 20°… and isonly to be taken as a guide. To determine finalspecificacations of chain, please consider allconditions together.○: Resistant X : Not resistant △ : Resistantdepending upon conditions - : Unknown
14-3 AbrasivenessPoints Concerning Lubricant(1) Install chain cover to avoid exposure to abrasive material.
(2) Select adequate conveyor type when exposing chain to abrasive material.
(3) Slow down chain speed as much as possible between pin and bushing.
(5) Lubricate through grease fitting. (Please consult with Korea Conveyor)
14.4 CorrosivenessWhen chain is exposed to corrosive materia:(1) Chain parts get thin. Wear is accelerated.(2) Rust affects rotation of roller and articulation of chain.(3) Special considerations to be taken for stress corrosiveness and intergranular corrosiveness when chain is used under acid or alkaline environment.
Please refer to Table 13 When selecting chain. It showsanticorrosiveness of chain material to various kinds ofsolvent. Chain parts made of 400 stainless steel my rustdepending upon conditions. Specifications for antistresscorrosiveness are available. (Please consult.) With regardto corrosiveness, please inform of materials ofaccessories and related equipment. For example, whenchain is used in a tank, the material of the tank isimportant information. In this case, it may be possible toprevent electric corrosion beforehand.

❶ Installation of SprocketProper alignment of sprocket and shaft if essential for smooth operation of conveyors and long lasting service of conveyor chain. To ensure correct alignment, proceed using following steps.
a. Level the shaft. Angular alignment should be adjusted within a gradient of 1/300.
b. Align the shaft for parallelism using a straight edge or a scale. Tolerance for parallel alignment of shafts should be within 1mm.
c. Align the sprockets axially on the shafts using a straight bar or a stretched wire as illustrated below.
Alignment accuracy should be as follows. Center distance up to 1m : ±1mm
1m to 10m :
over 10m : ±10 mm
Notes 1. It is required that at least three teeth of the sprocket are engaged with chain.
2. Installation of take-up unit is an effective way to adjust for chain elongation.
3. It is required to phase teeth of sprockets when multiple strands of chain are used in parallel.
❷ LubricationConveyor chain requires proper lubrication which reduces wear on the conveyor chain and economizes the horsepower. Lubrication is generally applied once a week by pouring or brushing ISO VG 100-150(SAE30-40)oil.
❸ Life of conveyor Chain and SprocketAs conveyor chain runs, wear appears on each part of the chain. The life of conveyor chain is determined not only by the pitch elongation but also by the wear of each component part. It is recommended to do periodical inspection on the wearing parts as per the following examples.
1) Roller
1⃞ “R” roller, “F” rollerIf the link plates start to contact with the track or rall due to wear of the rollers, replacement or chain is required.
When there is a comer rall, allowable wear amount is decreased by a dimension equivalent to “S”
2⃞ “S” rollerChain life comes to an end when holes or crevices apear on some rollers due to wear.
2) BushingChain can last until holes appear on bushings.
3) Link plateReciprocal friction between inner and outer link plates and contact between surface of roller and insidd surtace of link plate develop such wear as (A) and (B) in Fig.3.lf the amount of wear exceeds 1/3 of original plate thickness, tensile strength of chain is decreased critically. When such wear appears prior to that of other component parts, misalignment is the probable cause in most cases. Careful and periodical inspection is required to keep correct alignment of sprockets and shafts, refer to the first paragraph of installation of sprocket. For Flow Conveyor Chain, link plates slide directly on the material conveyed or on casing steel plate, the chain life ends when the wear amount reaches approx. 1/3 of “H” The following should be avoided as it may deform link plate hole or break chain;

1⃞To apply overload2⃞ To grind down outer diameter of pin, outer diameter of bushing and link plate hole or to heat up link plate at disassembly or assembly of chain.
4) Elongation of chain pitchWhen chain engages with sprocket or runs on the bent section of the track rail, flexion of the chain arises chain pitch becomes larger, the chain tends to cilmb the sprocket tooth. The limit of pitch elongation is generally 2% of the chain pitch.
To check elongation of chain pitch, measure as many number of pitches as possible (at least 4 pitches required).A = Pin center to pin center.B = Pin edge to pin edgeThe elongation of chain is calculated by comparing the actually measured pitch with the original chain pitch.
5) Wear of sprocketWhen a sprocket is worn out, chain tends to cling to the sprocket and to vibrate. In this case, build up welding is required for repair Although allowable wear amount slightly varies with conveyor type and chain size, it is recommended to repair or replace sprocket with wear amount 3-6 mm to prevent chain from being damaged.(A) Misalignment causes wear on side of sprocket teeth. Correction of the alignment is required.(B)
Check Point
When handling and dismantling Conveyor chains:•Always wear the proper protective clothing(safety glasses, gloves, etc.) suitable for the operations•When supporting Conveyor chains, make sure that the Conveyor chain and lt’s parts do not move freely•Pins should be inserted and removed in the correct direction.
Make sure to install safely devices(safety covers, etc.) onthe equipment all conveyor chains and sprockets.
Make sure that power is off before installation,dismantling, lubrication and maintenance inspection ofConveyor chains and take precautions to ensure that thepower will remain off throughout.
Perform operations in a safe manner by arranging thesurroundings so that no secondary accidents may occur.
When replacing Conveyor chains, note the following;
•The strengths of Conveyor chains differ depending on the maker. When a selection has been made at the time of purchasing or replacing based on this catalog, make sure to use our company’s products.
•Avoid replacing only areas that are partially worn or damaged. In such cases replace all with new parts.
