The invention relates to the technical field of engineering machines, in particular to a super lifting device, a crane and a control method of the crane. A mast, a traction rope guiding piece, a winchand a linear drive piece are included, wherein the winch and the linear drive piece are arranged on the mast. The traction rope guiding piece is arranged on the linear drive piece, and accordingly the traction rope guiding piece is driven by the linear drive piece to move in the direction away from the winch in the first direction. The first direction is the length direction of the mast. According to the purpose, for the problems that when a current hoisting arm hoists a heavy object, a traction rope is often in a tightened state, and the bending moment of the hoisting arm is difficulty shared through the traction rope and a super lifting mast, the super lifting device, the crane and the control method of the crane are provided.
本申请涉及工程机械技术领域,具体而言,涉及一种超起装置、起重机及其控制方法,包括桅杆和牵引绳导向件,以及安装在所述桅杆上的卷扬机和直线驱动件;所述牵引绳导向件安装于所述直线驱动件,以通过所述直线驱动件带动所述牵引绳导向件沿第一方向向远离所述卷扬机的方向运动;所述第一方向为所述桅杆的长度方向。本申请的目的在于针对目前起重臂起吊重物时,牵引绳往往难以处于紧绷状态,进而难以通过牵引绳和超起桅杆很好的分担起重臂的弯矩的问题,提供一种超起装置、起重机及其控制方法。
