This type of weighbridge is most suitable where the civil work for foundation is difficult or construction of a pit is expensive. Since the structure is above the ground, vehicles can only approach the weighbridge from two directions where the ramps are present. This type of weighbridge usually requires more space.
In a Pitless Type Weighbridge, RCC ramp work must be made at least three meters for both sides for easy movement of trucks or any other vehicles. Additionally, this clearance will give not stress out the engine of the vehicle.
The main advantages of the Pitless type weighbridge are
• Construction of a Pit is eliminated hereby reducing cost
• Since the platform above ground level, there are fewer chances of waterlogging during monsoon
• The nuisance of pit maintenance is eliminated.
• The maintenance is easy since all the parts are accessible above ground level.
