PIT TYPE WEIGHBRIDGE Our steel TRUCK SCALE decks offer higher strength, greater reliability and faster installation than conventional systems. Their simple foundations, fast, bolt-down sitting and innovative box construction have made them the preferred choice of operators across the country. You can choose either a Surface Mounted or a Pit Mounted TRUCK SCALE depending on the space availability. The platform of the truck scale is designed to withstand harsh environmental conditions. These weighbridges are installed in a pit, keeping them flush to the road surface. Because these bridges do not require ramps, they take up less surface area, making them ideal for smaller areas or sites where space is at a premium. Initial civil and foundation work can make pit installations a more expensive option. A pit is also prone to piling of debris and water logging, requiring provision of sump-pumps and manholes for maintenance purposes. Guide-rails are not required for pit mounted bridges.

BENEFITS

Costly Pit construction is eliminated.

Platform above ground level- No water logging during rainy season

Problem of pit maintenance is eliminated.

Easy maintenance since all parts accessible above ground level.

In Pitless weighbridges RCC ramp work must be required at least 3 meters for both sides for easy movement of vehicle

PITLESS TYPE WEIGHBRIDGE This type of weighbridge sits above of the road surface and requires ramps on either end to allow the vehicles to access the platform. The amount of civil foundations work required is reduced for surface mounted scales, but the overall space requirement is more. Before purchasing, check the overall height of the ‘Weighbridge’. Higher decks need longer ramps, which increase the overall footprint of the weighbridge as well as the turning circle for vehicles approaching the bridge. Generally, surface mounted weighbridges require guide rails fixed on the sides of the platform, which help vehicles to be aligned centrally on the bridge. This type of installation is better suited when the bridge may need to be shifted, or for temporary (sometimes called ‘portable’) installations. In most cases the site conditions, such as availability of space, will dictate the type of weighbridge available to you. Both surface and pit mounted weighbridges require a firm surface with load bearing capacity, the details of which will be specified in the ‘Plan of Foundation’ drawings provided by the weighbridge supplier. It may be advantageous to choose a weighbridge which has a common structural design for surface and pit mounting, this will allow future flexibility for changing the type of weighbridge

BENEFITS

Costly Pit construction is eliminated.

Platform above ground level- No water logging during rainy season

Problem of pit maintenance is eliminated.

Easy maintenance since all parts accessible above ground level.

In Pitless weighbridges RCC ramp work must be required at least 3 meters for both sides for easy movement of vehicle

LOW PROFILE MODULAR WEIGHBRIDGE: (FOUNDATIONLESS)

Modular Truck Scale needs no foundation, just smooth hard surface on which the load cell plates rest. This saves lots of cost and time. Pit / Pitless weighbridge foundation and installation takes 2-3 months while Modular Truck Scale can be installed in 2 hours. The modular design helps in easy cost-effective transportation and re-installation.

Main feature of Modular Weighbridge is “Ease of Erection”. Modular Weighbridge can be dismantled easily and again erected with ease at any other location. This is a new and revolutionary concept that offers high level of accuracy and lowest level of maintenance than major of the other weigh bridges. Available in both pit and surface mounted variants; modular weighbridge provides a very cost-effective solution for a wide range of applications.

All the weighbridges available today whether pit or pitless requires civil foundation costing at least Rs. 4 lakhs to Rs.6 Lakhs. This could be minimized to a great extent by installing our weighbridge. Our weighbridge could be installed as a pit mounted or pitless type permanently in a site if need arises. We hope that your choice of adapting a latest technology in weighing solution is much brighter and hence, we kindly request you to consider our offer favorably.

RAMPS: In the case of surface mounted weighbridges, approach ramps are required which can be of concrete or steel structure. Remember that ramps take the brute force of being hit by a vehicle as it mounts the ramp. Concrete can offer longevity, while steel is ideal if the weighbridge is likely to be moved.

Most suited for temporary sites Mobile Weighbridges We offer clients a wide range of mobile weighbridges. These are fully certified, totally mobile and self-contained unit that can be set up at virtually any location within minutes. Further its innovative designs also allow it to be towed by truck-tractor unit, or by tractor using a front trolley, thus reducing the involved transport costs.

TYPE OF LOAD CELLS: The load cell is the part of any scale that measures the weight or force being applied. The cells convert the force of the load into an electrical signal, which is further processed by a digital indictor. A weighbridge can have 4 / 6 / 8 / 10 / 12 or even more load cells. In basic terms, the load cell is the part of any scale that measures the weight or forced being applied. The cells convert the force of the load into an electrical signal, which is then read and displayed by a weight indictor. Load cells come in a range of different sizes, shapes, capacities and performance parameters. However, in the context of truck weighbridges, the basic distinction is ‘analogue’ and ‘digital’ load cells. Generally speaking, both analogue and digital cells use the same strain-gauge technology – but differ in terms of output of the load cell and therefore offer different benefits depending on the usage. ANALOGUE TYPE LOAD CELL: Analogue load cells are the most common solution. The output of analogue load cell is a continuous millivolt (mV) signal proportional to the applied load. Further processing and Analogue-to-Digital (A-to-D) conversion is done in the indicator. Analogue load cells can easily be paired with a variety of digital indicators across multiple brands. The load cells are further differentiated by design e.g. Compression, Shear-beam type.

The information can be transferred more effectively over longer distances between load cells and the indicator. However, the in-built electronics that offer these benefits makes these cells more costly as well as more complicated to repair. It is therefore important to check that your service provider is able to deal with a cell before taking the plunge.

Despite A-to-D conversion inside the load cell itself, a digital indicator is still required for calibration, display and stamping aspects. Many weighbridges that use canister cells position the cell low in the ‘bridge, close to the ground. Look for stainless-steel digital cells with a verified IP69K rating which offers protection against the dirt and water that can build up under the weighbridge.

DIGITAL TYPE LOAD CELL: Digital canister load cells are a popular choice in weighbridges. Unlike conventional analogue load cells, which rely on external wiring, junction boxes and A to D circuitry, digital cells offer additional protection from the unwanted electrical interference that can affect analogue load cells. Digital load cells can be pre-linearized, which allows faster installation and calibration, as well as featuring built in Diagnostic tools. Generally speaking, with digital cells, COMPRESSION TYPE LOAD CELL: Also known as canister type due to shape of its housing, these are the most popular choice for weighbridges in India. Compression type load cells using self-aligning (rocker) mounting enable the structure to float freely on the load cells. Excellent sealing and environmental protection is feasible. It is recommended to go for IP68 (immersion) and IP69K (pressure cleaning) certified products and with stainless steel construction for longer useful life.

SHEAR BEAM TYPE LOAD CELL : Available as single or double ended shear beam (the latter being more common in weighbridges), this type of load cell can offer slightly lower profile and less sensitivity to side-loads, but often with poorer sealing (potted) and corrosion resistance (alloy steel). These load cells are more advantageous in silo/ vessel weighing where rigid connections and head-room constraints are an issue as compared to a vehicle weighbridge where sealing and protection are very important.

LOAD CELL ACCURACY: Keep in mind that accuracy of a load cell has no relation to it being analogue or digital, compression or shear-beam type. All of these can offer an accurate and dependable solution, provided the load cell fulfils the accuracy criteria as set by the relevant certifying bodies (e.g. OIML R60 for India). Insist on approval certificates rather than conformance assertions. OIML : International Organization for Legal Metrology (OIML) is the highest body governing performance standards of load cells and weighing equipment. India is a member country of OIML. Load cells certified for compliance to OIML R-60 standards are globally accepted as mark of performance & quality.

IP 68 Protection EXPERT Make DOUBLE ENDED BALL AND CUP LOAD CELLS surpass Its Competitors in Terms Of Resistance against Side Forces. It Is a Fact That the Major Reason behind Load cell Manufacturing Is the Horizontal Side Forces Created by the Vehicles during Brakes and Sudden Start-Ups. That is why; Scales with Column Type Load cells require Construction Absorbing Side Forces. However, Such Construction As Rocker Supports, Tensions Rods, Buffers, Etc Need Maintenance And Have An Adverse Impact on Weighing Accuracy. For medium to high capacity applications, the double ended shear beam offers a number of advantages over other designs. Units like the one shown opposite have built-in jacking bolts which can be used to support the weighing structure during installation thus allowing the live load cells to be fitted just prior to commissioning, avoiding damage. The load cell is designed to rock on its mounting base to accommodate misalignment in mounting surfaces whilst still being retained. The mounting arrangement also permits limited movement to allow for thermal expansion and contraction as well as lift off protection.
