Excavation Braces Speed Shore Excavation Braces combine the benefits of aluminum hydraulic shoring with the ruggedness of steel box tubing in the most effective support system ever developed for shaft excavations. Specifically designed for shoring square and rectangular excavations, this perimeter support system provides for an unobstructed shaft, and is generally used to secure pits for pump stations, the installation or rehabilitation of manholes, tanks and vaults, or the operation of trenchless technology equipment. Excavation Braces, used in conjunction with appropriate sheeting, provide the active support necessary to secure safe excavations in less stable soils. Available in a wide variety of sizes and capacities, Excavation Braces are composed of modular sections for ease of assembly and transport. Excavation Braces feature 4-way hydraulic support with high-yield telescoping steel sections, and 4-way hose bridles for simultaneous cylinder pressurization.
