The invention discloses a lifting appliance for lifting an air spring. The lifting appliance comprises a buckle disc assembly, a clamping assembly and a lifting assembly, the buckle disc assembly comprises a buckle disc and a buckle hook part arranged on the periphery of the buckle disc; the clamping assembly comprises a first clamping arm and a second clamping arm which are symmetrically arrangedon the buckle disc, the lower end of the first clamping arm and the lower end of the second clamping arm are located below the buckle disc, and the first clamping arm and the second clamping arm canbe oppositely opened and closed; the lifting assembly comprises a lifting rod, and the lifting rod is connected with the clamping assembly; and when the air spring is lifted, an air pressure spring onthe upper portion of the air spring is temporarily fixed to the position below the buckle disc through the buckle hook part, meanwhile, the first clamping arm and the second clamping arm clamp an auxiliary spring on the lower portion of the air spring, and the air spring can be lifted and transferred by lifting the lifting rod. The lifting appliance has the advantages that safe and stable liftingis achieved, and the air pressure spring and the auxiliary spring can be synchronously stressed for lifting; and the operation is extremely simple and convenient, the clamping assembly can automatically clamp the auxiliary spring, and the more tightly the auxiliary spring is clamped during lifting.

    本发明公开了一种吊装空气弹簧的吊具,包括扣盘组件、夹持组件和提吊组件;扣盘组件包括扣盘和设置在扣盘周边的扣钩部件;所述夹持组件包括对称设置在扣盘上的夹臂一和夹臂二,夹臂一的下端和夹臂二的下端位于扣盘的下方,夹臂一和夹臂二能够相对开合;所述提吊组件包括提杆,提杆与夹持组件连接;当对空气弹簧实施吊装时,通过扣钩部件将空气弹簧上部的气压簧临时固定在扣盘下方,同时,夹臂一和夹臂二将空气弹簧下部的辅助簧夹持住,提起提杆即能实现对空气弹簧起吊转移。其优点在于:实现安全稳妥吊装,气压簧和辅助簧能够同步受力起吊;操作极为简便,其夹持组件能够自动夹紧辅助簧,且起吊时还能越夹越紧。
