PIT TYPE WEIGHBRIDGE
This type of weighbridge is most suitable for places with limited space e.g. non-hilly areas where the construction of pit is not a costly affair. Since the platform is in level with the ground, vehicles can approach the weighbridge from any direction. Most public weighbridges prefer this design.
Benefits
- Lesser Space Required (As it has no ramps)
- Rickshaws & Tractor Trolleys can also be weighed as platform is in flush with ground Level.
- No Ramp require for truck movement because it is installed in land surface level
- Costly Foundation
Robust Load Cells & 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.
Technical Specifications
| TYPE OF SCALE | PIT TYPE |
| Cost | More expensive due to additional construction work required |
| Service & Scale Repairs | In some cases, more costly due to confined area restrictions |
| Clean Out | Done manually and very time consuming |
| Scale Ispection | Must be performed from inside the Pit |
| Restrictions Or Hazaeds | Some states require specified clearances underneath scale.Must also deal with OSHA and confined space hazards regulations. |
| Approaches | 10′ Flat and level |
| Ramps | None |
| Electricity Needed | Must have electricity for pit lights and sump pump if no gravity drain is present |
ADVANTAGES
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 undergo 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 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.
