摘要： Disclosed herein is a ratcheting, self-aligning load-lifting device featuring a ram, responsive to a pressurized medium, having at least one rack of teeth and a keyway slot, and a ratchet mechanism encircling the ram. The ratchet mechanism has at least one pawl for engagement with the rack of teeth during elevation of the ram, a set screw extending into the keyway to maintain proper alignment of the mechanism, a spring plunger radially positioned for engagement with the keyway slot after the ratchet mechanism has been rotated and the pawl has been released from the elevated rack of teeth, and a biasing means positioned within and attached to rotate the ratchet mechanism thereby urging the re-engagement of the pawl with the lowered rack of teeth.
