All units are designed for quick and easy assembly, installation and extraction by one or two people from outside the trench. All units are fitted with mechanical lock-off valves for additional security and to further simplify the installation and extraction process. If the non-battered ends of the excavation require additional support, aluminium Waler End Bearers can be used to provide light weight support.

Hydraulic Waler Frames: Typical Installation Methodology

Waler frames provide 2-way support to trenches and are used in conjunction with trench sheeting. Each unit comprises 2 No. aluminium or steel rails strutted apart by two hydraulic cylinders. The latter are available in a range of different sizes depending on the trench width. This sequence explains the method for installing a Hydraulic Waler System, complete with optional End Bearers within a trench.
