Double Elevator Brake ensures safety of home elevators.

February 1, 2011

Intended for home elevators, Model RNB0.4WB-01 consists of 2 identical brakes mounted on one adaptor flange. Since brakes are holding only, both operate simultaneously when they are required to come on. In event of one brake failure, other unit is still capable of handling torque load required. Both brakes are equipped with limit switches that indicate when brake is either engaged or disengaged. Read More
