Unintended car movement can result from failures in the driving machine motor, brake, shafts, gearing, control system, or other critical elevator components. The A300-UCM actively monitors the elevator’s status and, upon detection of unintended motion, immediately triggers an electric or hydraulic rope gripper to stop and hold the car safely in place. This protects passengers, keeps the elevator within safe operating limits, and ensures compliance with ASME A17.1 Section 2.19.2 and NYC Appendix K 3.8.4.1.

By continuously monitoring for unintended movement and critical safety signals, the A300-UCM delivers a reliable, proactive solution for existing elevators. It minimizes risk, reduces liability, and provides peace of mind for building owners, contractors, and tenants alike.

All units include fully revised prints showing exactly how to connect the UCMP to the controller, live phone support in English and Spanish, and a 3-year warranty.
