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.
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 weighbridge RCC ramp work must be required atlest 3 meters for both sides for easy movement of vehicle. 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. Highly Durable Girders and Plates: 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 undergoes stringent quality checks as per ISI & IS 2062 Grade. Reliable Mounting Assembly for Load Cells: 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. Low Resistance Cables and Weather Proof Junction Box: 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 a 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. Easy to use Weighbridge Software: EAGLE Weighsoft - user friendly, windows based software for weighbridges. It is highly secure and customizable - password protected different user levels, allows you to create your own fields, depending on your specific requirement. FUNDAMENTAL CONSIDERATIONS

TYPE OF SCALE
|
PIT TYPE
|
PITLESS TYPE
|
|
COST
|
More expensive due to additional construction work required
|
Less expensive due to less construction work
|
|
SERVICE & SCALE REPAIRS
|
In some cases, more costly due to confined area restrictions
|
Less difficult or costly and serviced from above
|
|
CLEAN OUT
|
Done manually and very time consuming
|
Quick and easy, done with a water hose or compressor from the side
|
|
SCALE ISPECTION
|
Must be performed from inside the Pit
|
Can be performed by simply walking around the perimeter or the scale
|
|
RESTRICTIONS OR HAZAEDS
|
Some states require specified clearances underneath scale. Must also deal with OSHA and confined space hazards regulations.
