Abstract
A ratchet block comprised of a frame, movable sheave assembly, ratchet assembly, ratchet assembly and cam wherein the ratchet automatically engages under load permitting rotation of the sheave in only one direction, and disengages when the load is removed permitting rotation in both directions. This automatic engagement and disengagement of the ratchet to increase or reduce friction when a rope or wire is run through the sheave does not require the user to disengage the ratchet mechanism with a conventional switch.
