    The hoist is a common appliance for high-altitude operations.
    In order to ensure the safety of high-altitude operations, safety locks are set to prevent accidental falling of the lifting moving parts.
    When the hoist fails, the safety lock can ensure the safety of the operator

    The position of the safety lock in the existing technology is determined according to the working position of the lifting moving part.


    This kind of safety lock for hoist developed by Changzhou One Step solves the problem that the safety lock in the prior art cannot lock the lifting moving parts at any position to prevent them from falling

    The safety lock includes a rack fixedly connected with the lifting moving part and a gear fixedly connected with the vertical column of the hoist.
    The rack and the gear mesh; a ratchet wheel and a check valve pawl, and the ratchet wheel and the non-return pawl mesh
    .


    The ratchet wheel and the gear are installed together on the rotating shaft and the two keep synchronous rotation.
