Dragboxes provide a safe and rapid means of pipe laying in good, dry, stable ground. They should only be used when the ground will stand to the depth of the fully excavated trench and they are intended to act as a shield in the event of trench wall instability. The normal method of operation is for the excavator to drag the box forward by pulling on the front strut.
