Spreaders - Trench Box Spreader Sets

4-Pipe and 5-Pipe Sets

There are several variations in the style of common trench boxes. Some are designed to utilize 4 spreader pipe (such as those set up in a 4-pipe repair, also known as 4-pipe independent) which provides maximum pipe clearance through out the trench shield, 4-pipe pull which provide lower front spreaders to allow excavator boom clearance) and others are designed to utilize 5 spreader pipe.

The most commonly used spreader pipe on Pro-Series trench shields are the 8" schedule 80 spreader pipe. No matter if the trench box is set up to accept 4-pipe or 5-pipe, it is stated on our engineer stamped certification sheets that a minimum of 2 spreader pipes are required on each end with the approved pins and keepers. In general, the 5th spreader is used as a means to rigidity to larger, deeper trench boxes.

For specially designed trench shields that require 5 or more spreader pipe, or pipe of a different specification (i.e. 10" sch. 120), please refer to certification sheet.
