Maxi LadderSafe

The Maxi LadderSafe is a modular trench access system specifically designed for use with the Groundforce range of trench boxes. The system comprises a number of components, including the handrail/access head unit, clip on ladder extensions and stabilisers. A safety chain is provided at the entry/exit point for additional security. The system fits to most Groundforce box systems via various bolt on connection spigots.

Mini LadderSafe

Mini LadderSafe is a lightweight, temporary, gated access platform that uses a conventional ladder to gain access/egress to shallow excavations up to 4m deep. The system can be used on most trench sheet and steel pile profiles up to 25mm thick and on trench box panels up to 120mm plate width.

Trench Box

A trench box is generally the first choice for the rapid shoring of trench runs due to the speed and simplicity of installation. They are typically suitable for use in trenches up to 4.9m wide x 6.6m deep in reasonable ground conditions, they are not recommended in unmanaged, waterlogged ground. Groundforce offer a wide range of trench box sizes with various strut types, providing a safe solution on site. A trench box is versatile, cost-effective and provide an excellent way of protecting workers from excavation wall collapse while carrying out groundworks. They can easily be stacked and used in multiple runs, which also makes them the ideal shoring method for continuously supporting an extended length of trench. Some of the key benefits are:

Manhole Box

A manhole box is similar to a trench box in it's basic function, but they incorporate integral end return panels for extra ground support when placing pre-cast manhole rings, as an alternative to sheets and frames. There are five available sizes catering to common manhole ring sizes. They can be quickly assembled and installed without an operator needing to enter the unsupported excavation, supporting trenches up to 5.5m using the base module and various struts. Ideal for most ground conditions.
