The invention provides an engine packaging box lifting appliance, and belongs to the field of lifting appliance devices. The engine packaging box lifting appliance comprises a lifting beam, a main lifting chain assembly, two inserting plates, four lifting chains and a chain locking device; the main lifting chain assembly comprises a main hook, a first lifting ring and two main chains, and second lifting rings are symmetrically arranged at the bottoms of the two ends of the lifting beam; and when an engine packaging box is normally loaded, the included angle between the two main chains is 60 degrees, and the included angle between the lifting chains located on the inserting plates on the different sides is 60-65 degrees. By means of the arrangement, the residual swing time is shortened, thehigh loading and unloading operation efficiency of the engine packaging box is achieved, the included angle between the lifting chains located on the inserting plates on the different sides is changed by adjusting the lengths of the two lifting chains on the same side through the chain locking device, and angle adjustment is achieved; and meanwhile, the arrangement of the lifting appliance is reasonable, and the residual swinging time is shortened, so that the higher loading and unloading operation efficiency of the engine packaging box is achieved, the labor intensity is also reduced, and the use and the operation are more convenient and quicker.
本发明提供了一种发动机包装箱吊具,属于吊具装置领域。包括吊梁、主吊链组件、两个插板、四根吊链、锁链器;主吊链组件包括主挂钩、第一吊环、两个主链条;吊梁的两端底部对称设有第二吊环;正常负载发动机包装箱时,两个主链条之间的夹角为60°,位于不同侧的插板上的吊链之间的夹角为60°‑65°。通过上述设置降低了残余摆动的时间,从而达到较高的发动机包装箱装卸作业效率,通过锁链器的调节同侧两根吊链的长度,使得位于不同侧的插板上的吊链之间的夹角产生变化,实现角度可调,同时吊具的布置合理,降低了残余摆动的时间,从而达到较高的发动机包装箱装卸作业效率,也降低了劳动强度,使用和操作更加方便快捷。
