Heavy Duty Braces & Frames

The heavy duty braces & frames is designed for use in excavations up to 15 metres square. It can also be used in conjunction with the light duty manhole frame for fuel tank installation where the excavation sizes can be up to 15 metres long but minimal width.

Adjustment is achieved as the legs are extended using a double acting pump and two hoses. Fluid is pumped on both up and down strokes of the handle to make the extension or retraction faster. The hoses and legs are fitted with a combination of male and female couplers which ensure that the connections are always the correct way around. It also means that hoses can be simply connected end to end to allow the pump to be used from ground level on deeper excavations as required. Both hoses from the pump are connected to each leg in turn.
