The Drag Box is a custom designed shoring system for special project requirements. A Drag Box is lowered into a pre-excavated trench and pulled horizontally by a large hydraulic excavator. Workers are protected by the box walls against the dangers of the trench collapsing. Back filling of the trench takes place behind the box. Typical applications are cross country pipelines in depths up to 16.5' / 5.0m and with pipe diameters of maximum 9.9' / 3.0m. Depending on the pipe length the Drag Box can be up to 26.4' / 8.0m long.The width of the box can be extended by adding flanged extension bars.
