The Single Acting Manhole Brace range consists of a series of non-modular, (single piece) hydraulically adjustable legs which are connected together to support square or rectangular excavation sizes ranging from 1.15m to 3.0m.
The range consists of 5 individual legs, each incorporating a single acting hydraulic ram unit that provides on-site length adjustment in each leg. Note: these legs are relatively light duty in terms of load capacity and the single acting hydraulics necessitate manual retraction after pressure release.
