More Information
Summary:An elevator brake comprises an electromagnetic brake and a control circuit, wherein the electromagnetic brake is used for deceleration of a lift car, and the control circuit is connected with the electromagnetic brake and controls the electromagnetic brake to work. The control circuit comprises an input unit, a control unit and an output unit, wherein the input unit, the control unit and the output unit are connected in sequence. The input unit comprises an order module and a safe module, wherein the order module is connected with a control panel in the lift car, and the safe module is connected with a sensor detecting speed of the lift car. The elevator brake is not improved, a control device controlling the brake is only improved, and the electromagnetic brake having controllable braking force is utilized simultaneously. Therefore, on the basis that enough braking force is effectively supplied, the elevator brake has stable deceleration, detects the lift car and a tractor in real time, and accurately suppli
