Semi pit weighbridges from UltraHawke Scales and Systems are constructed partially in the ground, allowing the weighing surface to be installed at ground level.
This ensures that ramps are not required, reducing space requirements when compared to above ground weighbridges.
Excavating the pit for the installation of foundations for semi pit weighbridges is more expensive than the limited excavations required for above ground weighbridges, however, so this is a more expensive option.
Side walls are generally constructed one metre from the deck to allow for access to load cells.
An alternative to this approach requires the construction of side walls adjacent to the deck, and is a viable option provided access holes are constructed in either the deck or in the side wall adjacent to each load cell.
This ensures regular maintenance and cleaning activities can be carried out.
