The invention discloses a crane power transmission control method and device and a crane. The crane power transmission control method comprises: setting the maximum work displacement of a secondary component, corresponding to each gear of the crane; acquiring the current gear state and the specific gear of the crane; and according to the gear state, determining the work mode of the secondary component, and setting the maximum allowable displacement of the secondary component as the maximum work displacement corresponding to the specific gear. According to the crane power transmission control method and device and the crane, the maximum displacement of the secondary component is controlled in consideration of different gears, power impact can be reduced, a buffering mode is added, the influence of instant power loss produced after energy is released on the whole vehicle is avoided, vehicle shade resulting from unstable power caused when the vehicle is at a low speed or the system is suddenly cut off is avoided, the comfort and safety of a driver are improved, the rotating speed of the secondary component is limited, the service life can be prolonged, and the energy recycling efficiency can be improved.
