Steel Walers

About Steel Walers

A heavy duty steel waler system where stronger support is required.

Walers are compact, easily installed hydraulically-expandable shoring units designed for 2-sided support of trench runs typically up to 4m wide x maximum 6m deep. They are used in conjunction with trench sheeting in single frame (propped cantilever) or multi frame configurations.

Support schemes using walers should be designed by a competent engineer. Each waler unit comprises two horizontal rails, expanded against the sheeted trench walls by (typically) two externally interconnected 63.5mm bore hydraulic rams. The rams are expanded and pressured between the walls of the trench by a manually operated hand pump.

Benefits

  • Provides continuous close trench support when used with trench sheeting
  • Hydraulic cylinders allow variable trench width adjustment
  • Ideal for use where services and utilities exist
