POWER TRANSMISSION CONTROL METHOD AND DEVICE FOR CRANE, AND CRANE

摘要

Disclosed are a power transmission control method and device for a crane, and a crane. The method comprises: setting maximum working displacements of a secondary component corresponding to various gears of a crane; obtaining a current gear state of the crane and a specific gear; and determining, according to the current gear state, the working mode of the secondary component, and setting a maximum displacement allowed by the secondary component to be a maximum working displacement corresponding to the specific gear. According to the method, maximum displacements of the secondary component with respect to different gears are controlled, power impact can be reduced, by adding a buffer mode, the influence of instant power loss on the whole vehicle when energy is released can be avoided, vehicle bouncing due to unstable power when the vehicle is at a low speed or the system is abruptly disconnected is prevented, the comfort and safety of a driver is improved, the rotation speed of the secondary component is restricted, and the service life and energy recovery efficiency are increased.
