Spring loaded safety crank SIFEKU

The bi-directional self-braking crank is the safety upgrade to the traditional pawl-and-ratchet of yesteryear.  The safety benefits are two-fold; to the load it is cranking and especially to the operator whose hands and other body parts are at risk.

• Cow hoof trimming chutes and crushes
• Conveyors and loading decks
• Manually gear operated jacks
• Manually operated winches
