Electronic Weighbridge

The Eagle Make Pit Type Weighbridge is a heavy-duty weighing system designed for accurate and reliable measurement of trucks, trolleys, and commercial vehicles. Built with a robust pit-mounted structure, this weighbridge sits flush with ground level, allowing easy vehicle movement from all directions and requiring minimal approach ramps.

Manufactured using high-grade steel and advanced fabrication techniques, Eagle’s pit type weighbridge ensures long service life, excellent load-bearing capacity, and consistent weighing performance even in harsh industrial environments. The platform is equipped with precision load cells, a digital indicator, and optional software for data recording and reporting.

General Introduction :

• This type of weighbridge / Truck scale is most suitable where the excavation work for foundation is difficult or construction of pit is expensive. Since the structure is above ground level, vehicles can approach the weighbridge only from two directions where the ramps are provided. This type of weighbridge requires more space.
• In Pitless Type Weighbridge RCC ramp work must be required at least 3 meters for both sides for easy movement of vehicle.

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.

Robust Load Cells and Digitizers : The most important components of an electronic weighbridge are the load cells and digitizers. Eagle has made both of them very robust and hence, the best available in the country.

Advantage :

• A truck to be weighed is directly driven to the platform of a weighbridge and hence, the platform is subjected to the entire load and vibrations created by a moving truck. Our weighbridge platforms (made of steel) are designed very carefully to withstand these loads without damage and is highly durable. The girders and plates used in our platform are selected very carefully and undergo stringent quality checks as per ISI & IS 2062 Grade.
• The next most important component is the mounting assembly for load cells. This transfers the load from the platform to the load cells. This is a cradle assembly which is free to move in the horizontal axes and hence takes all side loads generated due to the vehicular movements on the platform. The mounting assembly consists of three parts namely, the Bottom Plate, Rocker assembly and Top Bracket.
• The signal from the load cells (in milli-volt) is carried to the digitizer, in the control room, through a 4 - core shielded cable. The cable has a very low electrical resistance and hence, no loss of signals. The cables from different load cells, in a weighbridge, meets in weather proof junction box. The junction Box is of fully molded type and houses the necessary terminal blocks for interconnection of load cell out puts. The Junction box also carries a set of surge arrestors, to protect the entire system from lightning and electrical surges.

Civil Work :
If you opt for our mobile weigh bridge with inbuilt steel foundation plates you don’t require any civil foundation work. For the erection of the weighbridge only a well leveled hard surface is required. The savings accrued because of this are :

• Savings in the cost of civil foundation works is approx. Rs.1,50,000/- in Small Size
• Savings in time to the tune of 20 days @ Rs.2500/- per day. This savings is recurring for every relocation of the weighbridge.

Details :

• Reduction In Load Distance - As Eagle weighbridge can be easily dismantled and re erected within a short span of time, it can be constantly relocated near to area of operation. This will help enormously in reducing lead distance, reduction of handling cost, manpower, and appreciable improvement in productivity.
• Accuracy - Eagle is a highly consistent system, as we use state of art electronic and structural design. Consistent accuracy is a basic necessity of any weighbridge. Even little inconsistent measurement will result in loss of several hundred kilograms of materials everyday, which can amount from Rs.1000/- to 10,000/- to any amount depending the value of material.
• Maintenance - As Eagle is a rugged design and the system has surprisingly ease of operation under most harsh condition. The down time due to break down is almost nil and hence the loss due to break down is also almost nil.
• Rattling - As Eagle weighbridge is a modular design which comprises of a fully welded modules rattling of the system due to loose fasteners is totally avoided. Such rattling leads to inconsistency and inaccuracy in weighing.
• Warping of Plates - The top deck plate is fully welded and well supported by longitude beams within a span of 1 meter; hence they are rigid and sturdy avoiding warping or bending of plates. This avoids replacement. Top deck plate, saving lot of time, money and work output. Since it is rugged the life span is also very high.
• Flexibility In Operation - Being a modular design the length of the weighbridge can be extended or reduced suiting the site conditions and hence no need to keep separate weighbridges. This flexibility help in reduction of inventories and capital cost.
• Our weighbridges can be easily dismantled and re-erected in a new location in a Short span of time. Transportation of the modules can be arranged through a normal Truck.
• Our weighbridges are modular type. Hence they have the advantage of future up-gradations by simply adding a module or two to have a longer platform. This is not possible in conventional type of weighbridges.
• Conventional type weighbridge has 2 main longitudinal members. Whereas the modular type weighbridge has 4 main longitudinal members. Structure is more strong, yet sleek.
• Our Weighbridges are fitted with load cells which supports the structure through a special arrangement. This ensures the structure swings in order to avoid the shock loading transferred directly to the load cell, on a dynamic force created by a moving truck over the platform and thereby load cell accuracy is sustained for a longer period.
• In our weighbridges, the chances of getting rusted is less as the modules are seamlessly welded and rain water and slush cannot find their way to the under chassis of the weighbridge which will definitely reduce the maintenance cost.
• Our Weighbridge is modular in structure, fully welded and strong to take care of the designated load. The loose parts such as girders, plates and transoms in a conventional weighbridge and the main girders in a surface mounted type have a relative movement due to cyclic loading of truck weighing, though they are held by fasteners. In the long run, this effect leads to wear and tear of the parts and the same need replacement. Our weighbridge comprises of modules which are fully welded and have no loose parts, hence the effect of cyclic loading does not cause any problem and thereby keeping your maintenance cost to a minimum.
• The conventional weighbridge with Girders and Plates or a surface mounted type has a 4 load cells support in its corners and the girder has long span and hence is subject to bending in the middle. This bending tilts the load cells out of its vertical position, resulting in load loss due to angular force over the load cell.
• In a typical surface mounted type, the structure is supported with load cells through rocker assembly which holds the structure rigidly and thereby the shock load due to dynamic force created by a moving truck is directly transferred to the load cells which not only reduces the life span of load cell, but also leads to erratic performance of load cells in due course.
• This weighbridge does not require an elaborate civil foundation work as in the case of a Conventional weighbridge. Our weighbridge could also be installed permanently on a hard surface with a concrete mat or on M.S. Plates under the load cell points and the ramps.
• 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.

Foundationless Movable Weighbridge :

• Mobile weighbridge needs no foundation, just smooth hard surface on which the load cell plates rest. This saves lots of cost and time. Standard weighbridge foundation and installation takes 2-3 months while mobile weighbridges can be installed in 2 hours. These weighbridges can also be shifted to another site easily. The modular design helps in easy cost effective transportation and re-installation.

Concrete Platform Weighbridges :

• With ever-rising steel prices, it makes great economic sense to install concrete platform weighbridges. Apart from low costs, it offers high strength and is virtually maintenance free – requiring no painting every year. Its life is 100 years as compared to that of 15 years of a typical steel platform. Due to the advantages of concrete platforms, the developed world has been using them for over 30 years. In Europe 95% of electronic weigh bridges are made with concrete platform.
• As the platform gets longer, cost saving increases. Modern day transportation is moving towards using longer trucks and trailers. MNC truck manufacturers, such as Volvo, who have started manufacturing in India, are introducing longer models which are capable of carrying heavier payloads. The concrete platform weighbridge can bear heavier loads. That is why all modern bridges that one sees on the city roads are either concrete or composite.
• A heavily loaded truck entering the weigh bridge gives heavy jerks on braking. Vibration thus caused, reduces the life and accuracy of the load cell and thus needs to be reduced to minimum. Vibration is much more in the case of steel as compared to concrete as it absorbs vibration.

Advantage :

• Cost - The cost of material required for construction of concrete platform is approximately 40% less than that of steel platform.
• Material quality - Quality of steel is always a suspect owing to the presence of a number of local companies which make cheaper and inferior quality steel, thereby decreasing the life & performance of steel components over time whereas the onsite construction of concrete weigh bridges helps monitor quality capacity.
• Enhancement - The construction of the concrete platform is designed so as to carry a load upto 100+ tons by using heavy duty load cells. Hence the capacity of the weighbridge can easily be enhanced up to 100 tons, if required, without incurring any extra cost whereas in the case of steel platform weighbridge, the capacity cannot be increased with the existing steel structure. Joints & plates of higher proportions would be required. Add to all this the cost of the cells which will need to be replaced.
• Maintenance - Due to rattling of steel structure, nuts & bolts get loosened thereby requiring periodic tightening. Also steel gets rusted due to changes in the environment over a period. Being a totally RCC structure, there is no rusting of components in concrete platforms hence they are totally maintenance free.
• Design - Steel being flexible tends to bend & rattles when the truck comes onto the platform. Due to this there is a lateral pull of the load cells wherein ideally the load should be transferred vertically. The concrete platform is a rigid monolithic structure. As soon as the vehicle comes over the platform, the load gets distributed to all 6-load cells.
• Strength - Steel structure being lighter by weight than the gross load of the vehicle coming on the platform, a cantilever effect takes place with inverse forces taking place at the ends thereby having a tendency to twist the steel structure & causing weighing errors. The concrete platform being a heavy mass has more stability. Hence, no inverse forces take place in the platform.
• Lightening - Steel structured weigh bridges are prone to electro-static charge & high electric field caused by strong winds & lightening which may damage the weighing instrumentation & load cells. The platform of concrete structure is totally immune to such environmental harshness, thereby the system more stable & maintenance free.
• Life - The steel platform/girder structure gets weak due to rusting & loosening of nuts etc. The top plate & joints have a bending effect after few years. The concrete platform has a very long life and no bending effect takes place.
• Transportation - The steel structured weighbridge is fabricated at works & is transported to site by truck for installation on the foundation thus incurring heavy transportation costs. The construction of the concrete platform is cast on the foundation, at site, thus saving on transportation.
