U-shape Lead Systems - GeoQuip Power Systems

A u-shaped lead, also known as a box lead or steam lead, is a lead formed in the shape of a “U” to provide guiding rails for the hammer in the open portion of the lead. This can be used with continuous flight auger (CFA) for projects where a hole needs to be excavated and concreted is injected under presser as the auger is being retracted.

The leads can be furnished with side mounted auger tracks for installation of continuous flight augers (CFA).
