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.
A portable hoist lifting frame kit comprising cantilever arm assemblies and a cross beam, the cantilever arm assemblies being adapted for mounting to a bracket support system from which a load to be raised will be supported, a hoist which is mountable to the cross beam, protrusion blocks for spacing the cantilever arm assemblies horizontally from the bracket support system, and extension arms for spacing the cantilever arm assemblies vertically from the bracket support system, the protrusion blocks and extension arms each being adapted for mounting to the bracket support system.
A portable hoist lifting frame kit comprising cantilever arm assemblies and a cross beam, the cantilever arm assemblies being adapted for mounting to a bracket support system from which the load to be raised will be supported, the kit including a hoist which is mounted to the cross beam, the kit further including clamping means for the cross beam which are arranged to permit the position of the cross beam to be adjustable relative to the cantilever arms.
A portable hoist lifting frame kit comprising cantilever arm assemblies and a cross beam, the cantilever arm assemblies being adapted for mounting to a bracket support system from which a load to be raised will be supported, an adjustable H frame, protrusion blocks for spacing the cantilever arm assemblies horizontally from the bracket support system, and extension arms for spacing the cantilever arm assemblies vertically from the bracket support system, the protrusion blocks and extension arms each being adapted for mounting to the bracket support system.
