Details

The size of the system required for your trench ground support depends on your maximum trench depth requirements and the size of the pipe sections you are installing in the ground. Our lightweight trench box system is generally most suitable for trench depths of up to 13.7ft and trench widths of around 12.1ft if used in conjunction without variable trench box struts.

All of our trench boxes come with strut pins to suit. As standard, our ground pins are 1.1in diameter round bar and 6.3in long, they have a shear SWL of 228kN and weigh approximately 2.2lb.

The lightweight trench box system is also incredibly easy to assemble and install. There are two main methods of installing the trench box in place: the first is to use the "dig and push" technique, the other simple approach is to simply dig out the excavation and then lower the lightweight trench box into place.

The lightweight nature of these trench boxes makes them perfect for smaller excavations and when your site equipment has a low lifting capacity, meaning you don’t have to rely on hiring expensive machinery to carry out your ground excavation works.

Our lightweight trench boxes are manufactured using high-quality steel. When it comes to safety, we don’t compromise on quality.
