The invention belongs to the field of steel rope, steel cable or chain hoisting mechanisms, and particularly relates to a lifting appliance and a lifting device. In order to solve the technical problems that in the prior art, a lifting appliance can only adapt to unbalance loading in one direction, and two different lifting appliances need to be replaced according to actual conditions during use, so that the lifting appliance is very inconvenient to mount and dismount, and time is wasted, the invention provides the lifting appliance. Four movable pulleys are arranged on the lifting appliance in the circumferential direction through corresponding rotatable pulley seats, and each movable pulley is provided with a first working phase which is located in the same vertical plane with the movable pulley on the adjacent side in the circumferential direction. The second working phase and the movable pulley on the other side adjacent to the circumferential direction are located in the same vertical plane after all the movable pulleys rotate by corresponding angles. By arranging the rotatable pulley seat, the winding mode can be changed under the condition that the lifting appliance is not replaced, so that unbalance loading resistance in different directions is realized, and the time for mounting and dismounting the lifting appliance is saved.

    本发明属于钢绳、钢缆或链条卷扬机构领域,特别是涉及一种吊具及起吊装置。为了解决现有技术中的吊具仅能适应一个方向上的偏载,在使用时需要根据实际情况更换不同的两套吊具,导致安装和拆卸吊具时很不方便、浪费时间的技术问题,本发明提供了一种吊具,吊具上通过对应的可转动的滑轮座沿周向布置有四个动滑轮,各动滑轮均具有与周向相邻一侧的动滑轮位于同一竖直平面内的第一工作相位,还具有在所有动滑轮均转动相应角度后与周向相邻另一侧的动滑轮位于同一竖直平面内的第二工作相位。通过设置可转动的滑轮座,能够在不更换吊具的情况下变更绕线的方式,从而实现不同方向的抗偏载,进而节省安装和拆卸吊具的时间。
