Drag Boxes
Drag boxes are large protective shields which allow operatives to lay pipes within their confines in safety. As an excavation progresses, the drag box is pulled along the trench line by the excavator to allow a continuous pipe laying operation to proceed. Drag boxes are best suited to open field situations with reasonable ground conditions and where there is no requirement for active support of trench sites.
