Abstract
A rigid high load lightweight block (1) has unidirectional high strength moulded fibre bundles (4a, 4b) in the side plates (3a, 3b) for the carrying of the major operating tensile loads within the block(1), thereby minimising the weight and maximising the load of the assembly.
Claims41
A rigid block having:
- at least one sheave mounted between opposed side plates for rotation about at least one corresponding axis,
- at least one of the side plates comprised of a portion of at least one elongate substantially unidirectional and substantially continuous fiber bundle, the portion passing around the corresponding axis and being molded in a rigid resin with lengths of the at least one fiber bundle extending from either end of the portion,
- whereby a tension load applied to said at least one sheave is transferred via the at least one portion to the lengths of the at least one fiber bundle extending from either end of the portion.

An elongate tension member comprising:
- a rod comprising at least one first bundle of unidirectional and substantially continuous fibers molded in a rigid resin at at least one end to form the rod, and
- an end terminating eye piece having an eye therein, said eye piece connected to the rod, said the eye piece comprising at least one second bundle of unidirectional and substantially continuous fibers molded in a rigid resin about the eye, said eye piece connected to the end of the rod,
- whereby
- tensile loads applied to the tension member are transferred via the rod end and the eye piece.
