Articulating crane terminology and types

Ancillary attachments: Devices attached to the crane that

perform functions other than lifting a load with a hook, such as forks, augers, grapples and a digging bucket.

Articulating boom crane: A crane with two or more boom

sections that pivot (articulate) using hydraulic cylinders; also known as a knuckle-boom crane.

Base: The main supporting structure of the crane that supports the stabilizer system and mast to the vehicle.

Boom extension: A telescopic (hydraulic or manual) boom section that extends the reach of the crane.

Mast: The vertical structure of the crane between the inner

(main) boom and the base.

Crane rating: A cranes gross lifting capacity established by the manufacturer.

Extension cylinders: The hydraulic cylinders used to extend and retract the boom extensions.

Gross capacity: The capacity listed on the crane’s load chart.

Hydraulic tank: The reservoir that holds the cranes hydraulic fluid.

Jib: A hydraulic boom section that articulates, extends and attaches to the end of the outer booms last extension.

6

A knuckle boom crane appears similar to a standard crane, except that the boom articulates at the

'knuckle' near the middle, letting it fold back like a finger. This provides a compact size for storage and manoeuvring.

7

Essential components and functions of crane and lifting equipment

Brakes: stops crane long movement and cross travel and hoist/lower movements when activated.

Ropes: attached to the cranes winch drum and the hook, used to hoist the load.

Sheaves: grooves in the winch drum and on the blocks that the rope(s) sit in and run through.

Load equalisers: system for equalising (spreading) the load weight across two or more ropes or sling legs.

Load indicators: device that gives the operator a load weight reading when the weight of the load has been taken by the crane.

Limit warning devices: device that gives a warning when the SWL of the crane is being exceeded.

Slings: lifting equipment – chain, wire and web slings etc.

Spreaders: type of lifting equipment – usually four cornered from which hang sling legs that are connected to a load. Or; a bar, pole or wooden batten placed between two legs of a sling to keep them apart to keep the sling legs apart.

Hooks: used for attaching loads to the crane and lifting equipment.

Bins: usually round or rectangular in shape that are filled with the load material being lifted.

Tongs: two limbed piece of lifting equipment used to handle materials that should not be touched.

General precautions for crane operation

21

• Operation of cranes varies by make and model. Become familiar

with crane controls and load charts before attempting to operate it. Pay particular attention to the folding and unfolding process.

• Do not operate crane unless there is sufficient light to see the

boom tip and your load.

• If the load or placement area is not visible from operator’s position, establish proper crane communication with a qualified

signalperson.

• Never perform a manoeuvre that causes the load to pass over the operator’s position or another person.

• Establish a minimum 3.05m safe distance around the work zone by means of recognized safety identifiers such as cones, tape or barriers.

A MOVING BOOM WILL CAUSE DEATH OR SERIOUS INJURY

Stand on the side opposite the boom when folding or stowing crane. Stay clear of the boom when operating or servicing the crane.

General precautions for crane operation

• Do not move the vehicle with the boom unstoward. • Always operate the crane with smooth and gentle movements. Do

not jerk the controls to full speed, doing so is a major cause of shock loading.

• To minimise load swing position the boom tip directly over the

load’s centre of gravity prior to lifting. • Avoid quick or jerky movements at full extension as they can cause

undue stress and wear to the crane. • Always lift the load clear of the ground ( resting surface) with

boom lift or hoist before rotating the boom, extending or retracting the boom or moving the load in any manner.

Structural damage to boom Load could topple Stabilizers could lift

Likely results of dragging a load

22

• All loads shall be well secured and balanced before they are lifted more than a few inches

• Be sure the lift and swing path are clear of obstructions.

• Lift and move the load smoothly, always keeping the

load as close to the ground as practical.

• Do not move the load or attachments in such a way that they can make contact with any portion of the crane.

Load movement

Operator responsibilities

• Only one operator shall operate the crane at a time. • Do not engage in distracting activities while operating the

crane. • do not operate the crane when physically or mentally unfit or

under the influence of alcohol or drugs.

Handling the load

• Never load crane beyond the specifications of the load chart.

• Prior to the lift, calculate the load weight and range

capacity, accounting for the full range of potential configurations during the entire lift.

• Do not handle loads with the outer boom or fly jib in a negative position. This will shock load the joints or blow a hydraulic hose.

23

SWL of the crane measured in metres of length

25

Load placement

• Do not rest loads on structures of unknown load bearing capacity. • No one shall stand or pass under an elevated load.

Leaving the crane unattended (when leaving the work zone)

• Land the load – do not leave it suspended. • Lower the boom • Disengage the main power source/power take-off (PTO) to prevent

unauthorised use. • Stop engine and secure the key.

Power failure

• In case of power failure, set all brakes and locking devices. • Move all power controls to the off or neutral position. • If load can be controlled, land the suspended load

26

Ending operations

• Prior to transit always fold or stow the crane boom as directed in the operator’s manual.

• Raise the stabiliser legs completely prior to retracting the stabiliser beams completely

• Ensure the stabiliser beam locks are engaged and working properly. • Disengage the PTO, stow chocks and secure all loads and

attachments on truck bed for travel. • Perform final walk-around visual check to ensure the crane is ready

for transit.

In transit (loaded or unloaded)

• The vehicle driver must know the total height, axle loadings and gross

vehicle mass (including crane, ancillary equipment and load). • Ensure bridge ratings are sufficient to handle the weight of the vehicle

travelling across it. • Travel only with the boom fully retracted and in a traveling (stowed)

position. • Disengage the main power source/power take-off (PTO) to prevent

unauthorised use. • Stop engine and secure the key.

Maintenance and service

• Only authorised personnel shall perform maintenance functions on the crane; then only at the direction of supervisor.

• Disengage the PTO before any service repairs are performed.

• Do not disconnect any hydraulic hoses or components while there is pressure in the lines.

• Never tamper with hydraulic valve pressure settings. • Before welding on the carrier truck always; Consult manufacturer or representative for authorisation. Ground the welder as near the welding site as possible. Disconnect all connections to the crane’s remote control power box.

Disconnect the truck batteries.

32

Load hook inspections

• Inspections and record-keeping requirements for hooks are determined by the kind of equipment the hooks are used on. When the inspection requirements for hooks are specified in regulations applicable to your equipment those regulations will take precedence over the information presented here.

• Prior to initial use, inspect all new and repaired hooks to ensure compliance with items listed in the hook inspection checklist.

Load Hooks

33

Latches

• Use a hook equipped with a latch at all times, except when a latch proves impractical or poses a danger in a particular application.

• The latch is used to retain such items as slings and chains under slack conditions.

• Hook latches for loose sling retention are not anti-fouling devices.

They must never be allowed to support any portion of the load. Hook latches must be inspected for damage just as the hook must be inspected. Ensure the latch is in place and properly centred on the hook.

• Hook latches should never be crowded by oversized rope or stiff riggings.

• Make certain the load is properly seated on the “bowl-saddle” before a lift is attempted.

Lift equipment & attachments are checked for serviceability

Scrap Grab: Designed for scrap metal, such as car bodies.

Attachment must be secure, and No obvious signs of hydraulic oil leaks

Wire slings: Used for loads that require long and large

capacity slings.

Sheaves: Lead the rope over the head of cranes and hoists and are used in pulley systems. Must not be fouled in any way, and Allow free movement of wire rope

34

The factor of safety is the ratio between the minimum breaking load and the safe working load(SWL).

Chain Slings: Designed for general use on all types of loads. Factor of safety 4 To 1 Links should not be damaged or stretched.

Must be certified with a metal tag.

Synthetic Sling / Nylon Sling: Used for loads that require flexibility and resistance to abrasion and cutting. Factor of safety 6 to 1 Must not be frayed along the edges, or Ripped, cut or knotted.

No excessive wear or chemical stained

Flexible steel wire rope slings are flexible and resist

damage and kinking. Factor of safety 5 to 1

Brick Forks: Used for lifting palletised loads. These must be certified, and

Have no damage to the lifting eye’s.

Rigging general precautions

• Only the crane operator or other qualified persons shall attach a load to a crane’s hook.

• Never exceed the Safe Working Load or Working Load Limit of each piece of rigging. All SWL’s or WLL’s are rated for a straight vertical lift.

• Visually inspect rigging before each use. Remove from service any items meeting rejection criteria.

• Avoid shock loading. • Do not allow any body parts to get in between the sling and

the load.

• Personnel shall not ride the sling. • When multiple slings are used they should be attached to the

bow of the shackle and the hook to the shackle pin. • Do not pull sling(s) from under a load when the load is resting

on the sling(s).

35

• The centre of gravity is the central point at which the load weight would be evenly distributed to any side; this is also referred to as the balance point.

• Determine a loads' approximate centre of gravity before hoisting. • The load must be rigged over the centre of gravity (placing it directly below the load hook) or the load will shift when hoisted. • If the load has uneven weight distribution

place the rigging over where you think the C of G is and do a test lift. Adjust as necessary.

Basic hitches

Vertical or straight attachment is simply connecting

a sling from a lifting hook to the load. Full rated load of the sling may be used, but never exceeded. A tag line should be used on such a lift to prevent rotation which can damage sling.

Choker hitches reduce lifting capability of a vertical sling because this method of rigging affects the ability of the sling components to adjust during the lift, placing angular loading on the body of the sling and creating a small diameter bend in the sling body at

the choke point. Provides excellent grip and control.

Basket hitches distribute a load equally between the two legs of the sling and capacity is based on the

angles at which the legs are rigged to the load. When using a basket hitch, balance the load to prevent slippage.

Bridle hitches are defined as two or more slings working together and attached to the same collection point. They can be attached to the

hoisting hook by means of a master link or shackle.
