Mini Trench Box

Description

Lighter than our standard trench boxes, our mini trench box allows you to provide a safe and economic method of safety when your work force are in a deep excavation.

Our Mini range of Heavy Duty Trench Boxes can accommodate excavations as small as 2 metres. Spindle and extension range from 650mm to 4.5 metres external. Can be employed at depths up to 5.3m.

We also have available a trench box ladder access system build into our trench box safety panels. This eradicates the need to use ladders in excavations. Our Temporary works design service is also available for this trench box range.
