ROTATABLE ENGINEERING MACHINERY AND METHOD AND DEVICE FOR CONTROLLING ROTATION THEREOF

摘要

Disclosed are a method and a device for controlling the rotation of rotatable engineering machinery, used for solving the problem of low stability when there is a change in the rotational speed of a crane in the prior art. The method comprises: saving the rotating set information comprising the target rotating tangential acceleration (A1, A2, A3, A4) corresponding to the operating radius (R1, R2, R3, R4) of the engineering machinery respectively; after receiving a rotation activation command, determining the present target rotating tangential acceleration according to the present operating radius of the engineering machinery and the rotation set information; and controlling the rotation of the engineering machinery according to the present target rotating tangential acceleration. The method and the device aid in preventing the influence of additional rotating dynamic bending moment on the stability of the whole machine, such that the operating safety of the engineering machinery is improved.
