The BV100 Standard Manhole Box is a four-sided mechanical manhole excavation support system, ideal for installing pre-cast concrete manhole rings, small chambers, and tanks where ground movement is non-critical. With six sizes available to suit common pre-cast manhole ring dimensions, the BV100 manhole box delivers a fast, safe, and precise alternative to using sheets and frames in trench runs.
Unlike standard two-sided trench boxes, the BV100 manhole box incorporates integral end return panels, providing additional ground support on all four sides. The system assembles and installs quickly without requiring an operative to enter the unsupported excavation, significantly reducing risk during setup. For manhole box hire operations on deeper excavations, the base module combines with two box tops and a variety of strut types to reach depths up to 5.3m.
A Trench Guard edge protection system is available for use with this product, and four-way handling points aid safe assembly. Bottom cutting edge design allows for dig and push or excavate and place installation, and a Ladder Access System is also available for compliant operative access.
