Backhoe Trench Box

The Backhoe Trench Box is a robust piece of equipment, which acts as a safety shield to provide a safe working area below ground level. For use when working on excavations and pipe laying operations. The backhoe trench box can sustain working earth pressures of up to 20kN/m2. Users should check that the excavation will not impose greater pressures than this.

Installation is easy through the ‘Dig and Push’ method. This ensures that the side walls of the excavation are supported, and minimises the likelihood of an accident. The Panels are 3m long by 2m deep with a width range of 600mm to 2400mm which can be altered using telescopic struts, these are secured in place using the ‘Pin and Clip’ system, which connects all components. Backhoe box tops can be used to obtain 3m in depth.
