Abstract

The present disclosure provides a high-safety electric capstan including a hoisting mechanism, an electric motor configured to drive the hoisting mechanism to rotate, a user controller and an engagement assembly, and further including a control section electrically connected to a signal receiving actuator. The electric motor and the signal receiving actuator are electrically connected to the engagement assembly, respectively. The control section is configured for a user to send a trigger signal to the signal receiving actuator, the signal receiving actuator is configured to control an operation of the electric motor responsive to instructions from the user controller for a period of time when receiving the trigger signal, after the period of time, the signal receiving actuator is not responsive to instructions from the user controller. The solution of the present disclosure is advantageous for improving safety in use of an electric capstan.

Claims (6)
