ABSTRACT:
A forklift-type lifting apparatus comprises a pair of C-shaped claws or forks and integral frame structure and is adapted to be initially supported from a center spring-loaded cable. The center or point of balance cable assumes a taut position as a load is lifted and four outer corner cables take up the load. Alternatively, after the load is being supported by the outer four cables, the center spring-loaded cable may be detached.
