ABSTRACT:
A sliding strap for lifting loads wherein a strap is connected to a shackle providing a hook engaging loop and the strap at one end is fed into a rotatable assembly provided with two juxtaposed carrying pins spaced to provide a passage therebetween, and a receiving pin. The carrying pins passage permits the strap to pass therethrough. The receiving pin is aligned with this passage to allow the strap to loop around the receiving pin and pass through the passage. Rotation of the assembly serves to wrap the doubled strap around the three pins. Flanges are provided fixed to the rotatable assembly. A series of holes are provided in the flanges and in the shackle to permit the insertion of a locking pin when a pair of flange holes are aligned with a pair of the shackle holes.
