4 Way Hydraulic Brace System
A 4 Way Hydraulic Brace System is constructed from 3” aluminum cylinders, 6” square HSS sections and a corner bracket. The system is generally for manhole pits, utility pits, and small-bore pits. The system is intended to be completely assembled and lifted into place from outside the excavation.
The frames can generally be lifted in with backhoes and boom trucks; however, extreme caution should be used to make sure that allowable lift configurations for the equipment are not exceeded. Additionally, larger length, width, and depths may be achieved using a design by an engineer.
