Abstract
A portable hoist lifting frame kit has a cross beam 12 that can support an electrically, mechanically, hydraulically or pneumatically operated hoist. The cross beam is secured to or supported by cantilever arms 9 which in turn locate into extension arms 4. The cross beam can move laterally along the length of the cantilever arms. The extension arms locate into protrusion blocks which in turn locate into a wall mounted bracket support system designed to support the load to be raised. The bracket support system is of the mild steel channel type with return lip such as 'unistrut'. The portable hoist lifting frame kit can be assembled in various configurations i.e. it can be used with or without the protrusion blocks and extension arms.
