The BVB Backhoe Manhole Box is a four-sided excavation support system with integral end-return panels, purpose-built for installing pre-cast manhole rings in confined or inner-city environments where standard manhole boxes are too heavy for the available plant.
This lightweight manhole box uses a dig and push installation method, supporting all four sides of the excavation simultaneously and reducing accident risk for operatives below ground. The BVB backhoe manhole box suits working depths up to 2.96m and sustains earth pressures up to 20kN/m2, making it the right choice for shallower manhole and chamber installations where speed and manoeuvrability matter.
Various strut lengths are available for non-square configurations, and closing panels support the open ends of the box where needed. Trench Guard edge protection panels and four-way handling points for safe assembly are available to complete the setup. For four-sided excavation manhole support on inner-city sites with restricted access, the BVB backhoe manhole box delivers a compact, safe, and efficient solution.
