FAQs

What is the difference between a conventional Trench Box and a Rolling Strut Trench Box?

The Rolling Strut Trench Box differs from a conventional fixed strut position trench box in that the rolling struts enable both plates to move independently of each other during installation and removal. This means that plates can be pushed down to different levels for stepped trench excavations.


What is the benefit of using a Rolling Strut Trench Box?

During the installation process, parallel plate movement vastly reduce the potential for horizontal soil movements compared to more conventional box strutting systems.


What applications are best suited to using a Rolling Strut Trench Box?

Because Rolling struts allow for parallel plate movement and variable strut positions, they are ideal for the installation of large diameter pipes or culverts.


What is the maximum under strut clearance of a Rolling Strut Trench Box?

The construction of the Rolling Strut Trench Box enables greater under strut clearances of up to 3.1m in comparison to conventional trench boxes.


Are top boxes available for the Rolling Strut Trench Box?

Yes, top extension boxes can be added to increase the height of a base box.


What size excavations can Rolling Strut Trench Boxes be used for?

They are suitable for use in trenches up to 6.6m wide x 6m deep (with a top box).


Do Rolling Strut Trench Boxes have any limitations?

In general, Rolling Strut Trench Boxes are not recommended for use in unmanaged, waterlogged ground.


Do Groundforce offer training courses?

Groundforce Training Services offer industry leading accredited safety training primarily for those working in utilities, construction and civil engineering. From short duration health and safety awareness to more complex or specialist safety consultancy solutions.

Trench Boxes: Typical Installation Methodology

This quick and easy method ensures ground stability within a trench and helps minimise the excavation area to avoid damage to neighbouring structures and utilities in the ground. This methodology is best suited for trench boxes with shorter struts, if you use a trench box with long struts then other methods may be more suited, if you have any questions on different methods you can use contact our technical department.
