The invention relates to the technical field of lifting appliances, and discloses a lifting appliance for a crane, which comprises a connecting mechanism, an inner supporting mechanism and an inflating mechanism. According to the lifting appliance for the crane, the elastic air bag can uniformly act in an inner cavity of a lifted barrel by utilizing the space limiting capacity of the elastic air bag in an expansion state, so that the contact area of the elastic air bag and the inner cavity of the lifted barrel is enlarged, the pressure intensity of the elastic air bag on the lifted barrel in unit area is reduced, and the structural precision of the inner cavity of the lifted barrel is ensured; in addition, the device has an air pressure warning effect, and the optimal air pressure influence on the hoisted barrels with different weights can be deduced, so that the negative influence on the hoisted barrels due to insufficient or overlarge air pressure injection is reduced.
本发明涉及吊具技术领域,且公开了一种吊车用吊具,包括连接机构、内撑机构以及充气机构。该吊车用吊具,利用弹性气囊在膨胀状态时的空间限制能力,使得弹性气囊能够均匀作用在被起吊筒体的内腔中,从而扩大与被起吊筒体内腔的接触面积,以降低单位面积弹性气囊对起吊筒体的压强,从而保证被起吊桶体内腔的结构精度,此外,该装置具备气压警示作用,能够推导出对不同重量的被起吊筒体的最佳气压影响,从而降低由于气压注入不足或者过大对被起吊筒体的负面影响。
