Drag Box

Drag boxes are designed to act as moveable shields to provide local support as trench drag boxes in ground conditions that are reasonably stable or self-supporting in the short term. Drag boxes are intended to be pulled along as the excavation progresses and come in various specifications including lightweight options.

Drag box trench support

Drag boxes are not meant to be used for full panel height support of trench walls like a trench box but they do increase safety for pipe laying operatives. Some drag box types may permit the use of a top extension box so will need to be used with an excavator for safe handling of drag box shoring equipment.

3m Light Duty Drag Box

The Light Duty Drag Box is designed to act as a shield for pipe laying gangs when working in self-supporting ground. They can be used in up to 3m deep trenches by adding a top extension box to the base box. They are usually delivered to site ready assembled.
