Automatic cable-handling control system for electric excavators

An automatic cable-handling control system for electric excavators comprises a first sensor, a motor controller and a second sensor; the first sensor is used for detecting moving speed and direction of a travelling motor of an electric excavator and transmitting detection data to the motor controller; the second sensor is used for detecting speed of a cable drum and feeding back detection data to the motor controller; the motor controller processes the data collected by the first sensor and the second sensor and outputs different electrical signals, according to the moving speed and direction of the electric excavator, to drive the motor to rotate at different speeds, and the cable drum is driven to handle a power cable at the corresponding speed. The automatic cable-handling control system has the advantages that the automatic cable-handling control system allows a power supply system of the electric excavator to be better, handling of the power cable is facilitated, the flexibility and maneuverability of the excavator is greatly improved, and safety of the power supply system is also improved.
