More About Buying Ratchet Cranks Available in 14mm and 17mm square drives, these safety ratchet cranks are spring-operated and fitted with a folding handle. The load is securely held in the pushing and pulling direction at every height. The SIFEKU cranks also boast a silent operation and heavy weather/temperature resistance thanks to their enclosed design. No ratchet is required and a braking effect is achieved at both ends. These cranks have a 250mm radius for use on jacks up to 5000kg capacity. They are also recoil-proof and maintenance-free.
