The invention provides a lifting appliance device and hoisting machinery, and relates to the technical field of hoisting machinery. The lifting appliance device comprises a lifting appliance upper frame, a lifting appliance and a first damping structure. The lifting appliance upper frame is movably connected with the lifting appliance, and the lifting appliance can selectively move close to the lifting appliance upper frame or move away from the lifting appliance upper frame until a first preset gap is formed between the lifting appliance and the lifting appliance upper frame. One end of the first damping structure is connected to the lifting appliance upper frame, the other end of the first damping structure is connected to the lifting appliance, and the first damping structure is used for providing damping force for the lifting appliance and the lifting appliance upper frame when the lifting appliance and the lifting appliance upper frame approach each other. The invention further provides hoisting machine machinery which adopts the lifting appliance device. According to the lifting appliance device and the hoisting machinery, the technical problem that in the prior art, electrical elements are prone to failure and damage due to the fact that the anti-seismic effect of the electrical elements on the lifting appliance upper frame is poor can be solved.
本发明提供了一种吊具装置及起重机械,涉及起重机械技术领域。该吊具装置包括吊具上架、吊具和第一减震结构。吊具上架和吊具活动连接,且吊具能选择性地靠近吊具上架移动,或者远离吊具上架移动至与吊具上架之间形成第一预设间隙。第一减震结构的一端连接于吊具上架,另一端连接于吊具,且第一减震结构用于在吊具和吊具上架相互靠近时向吊具和吊具上架提供阻尼力。本发明还提供了一种起重机械,其采用了上述的吊具装置。本发明提供的吊具装置及其中机械能解决现有技术中吊具上架上电气元件的抗震效果不好导致电气元件易失效损坏的技术问题。
