ABSTRACT:
A crane 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 an over-center spring-loaded device for improved accommodation to varying non-level or off-balanced loading conditions. The center or point of balance cable assumes a taut position as a load is lifted and the four outer corner cables then take up the load. Means is also provided for enclosing the C-forks once a load has been positioned on the C-forks.
