Waler End Bearers
The aluminium Waler End Bearer (WEB) system has been developed to be used exclusively with the Groundforce range of aluminium Waler Rails to provide lightweight support to non-battered ends of trenches. Reference should therefore also be made to the Hydraulic Waler Frame User Guide.
Used with trench sheets, this system efficiently & safely retains backfill and prevents accidental dislodgement of loose material into the excavation whilst providing a barrier to prevent unauthorised access to the excavation. It also removes the need to improvise with less suitable methods, such as road plates or timber.
Each WEB comprise free-running, telescoping aluminium sections that pin directly into the aluminium waler rail which adjust in length as the hydraulic cylinders are extended.
