Steel Walers
Steel Walers are for use in medium and heavy duty trench support applications in conjunction with trench sheets or piles.
- Each unit comprises 2No. steel rails and a 2No. hydraulic cylinders of varying lengths.
- Cylinders are pressurised against the walls of the excavation using a small hydraulic hand pump.
- A choice of mechanical or hydraulic struts can be used with some models.
- Higher load capacity than the equivalent sized aluminium walers.
- Can accomodate trench widths from 0.85m up to 4.30m wide.
- Used in conjuction with trench sheeting .
