The invention provides hoisting equipment and a hoisting method, and belongs to the technical field of engineering equipment. The hoisting equipment comprises a portal frame, a transfer chain wheel which is connected to the top of the portal frame in a rotating mode, an electric hoist which is arranged on the portal frame, a chain and a hydraulic pump. The free end of the chain is used for hanginga hoisted object, the middle of the chain passes through the transfer chain wheel and then is wound onto the electric hoist, and the other end of the chain is connected with the hydraulic pump. The chain can be controlled by the hydraulic pump to be flexible or rigid. The hoisting method includes the steps that after the to-be-hoisted object is away from the ground, the to-be-hoisted object can be kept stable by frequently controlling the chain to be switched between the flexible state and the rigid state, and shaking of the to-be-hoisted object is reduced. The hoisting equipment and the hoisting method have the advantage that operational safety can be improved.

    本发明提供了一种起吊设备及起吊方法,属于工程设备技术领域。起吊设备包括龙门架、转动连接在龙门架顶部的中转链轮、设置在龙门架上的电动葫芦、链条和液压泵,链条的自由端用于悬挂起吊物件,链条的中部通过中转链轮后卷绕在电动葫芦上,链条的另一端连接液压泵,链条可通过液压泵控制使其呈柔性或呈刚性;起吊方法包括:在待起吊物件脱离地面后,通过频繁控制链条在柔性和刚性之间切换,使待起吊物件保持稳定,减小其晃动。本发明具有能够提高作业安全性等优点。
