Waler Frames provide two way support to trenches and are used in conjunction with trench sheeting. Various specifications of Waler Frames are available varying from lightweight aluminium to super heavy duty steel rails.

    Each unit comprises 2 No. aluminium or steel rails complete with two hydraulic cylinders. The cylinders fit directly on to the rails and are pressurised by a manually operated hydraulic hand pump, giving an uninterrupted column of strength between the trench walls. 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.

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.
