With a ratchet handle, the model MR hand winches can be hoisted and unwound with left and right reciprocating motion. You can work directly on the wall or floor even in a narrow space where you cannot rotate the handle. This model can also be used as a rotating winch like the model GM.
The Type-SI is fit for schools, public facilities, places accessible to unidentified numbers of people, or other places where the winch may malfunction if its stopper arm, which is able to release the brakes, protrudes from the system itself.
With the stopper mechanism contained in a hermetically enclosed special clutch cover, you can work to wind up and down the target equipment without the risk of malfunction.
The Type-SI can be manufactured for all stainless steel ratchet hand winch models.
When ordering, please specify, for example, ERSB-5-SI, RST-5-SI.
