The embodiment of the invention provides a control method and device for mast rotation of a crane, and the crane, and belongs to the field of cranes. The control method for the mast rotation of the crane comprises the following steps: an included angle value between a mast and a rotary table and a distance between the mast and a mast jacking support are obtained; and the mast rotation is controlled according to the included angle value between the mast and the rotary table and the distance between the mast and the mast jacking support. According to the invention, by means of the included angle value between the mast and the rotary table and the distance between the mast and the mast jacking support, the mast rotation can be controlled in time by combining the action of the mast and the state of the mast jacking support, so that the situation of cracking or deformation of a longitudinal beam of a mast is effectively reduced.

    本发明实施例提供了一种起重机桅杆转动的控制方法和装置及起重机,属于起重机领域。所述起重机桅杆转动的控制方法包括:获取桅杆与转台的夹角值、桅杆与桅杆顶升支架的距离;根据所述桅杆与转台的夹角值以及桅杆与桅杆顶升支架的距离,对桅杆的转动进行控制。本发明利用桅杆与转台的夹角值以及桅杆与桅杆顶升支架的距离,可结合桅杆动作和桅杆顶升支架的状态,及时对桅杆的转动进行控制,有效的减少了所述桅杆纵梁开裂或变形的情况。
