The invention discloses a lifting appliance, a crane and a lifting method, and belongs to the technical field of lifting equipment. The lifting appliance comprises a lifting beam, a connecting piece, a plurality of main-load lifting belts and a plurality of no-load lifting belts, the main-load lifting belts are connected to the lifting beam and a lifting plate, the main-load lifting belts are movably connected with the lifting beam so that the positions of the main-load lifting belts on the lifting beam can be adjusted, the no-load lifting belts are connected to the lifting beam and the lifting plate, at least one no-load lifting belt is detachably connected, and under the condition that the lifting plate is connected with a hoisting mechanism, the main-load lifting belts can be adjusted. And the lifting beam is lifted through the main load lifting belt or the no-load lifting belt. When the lifting appliance is used for lifting, the position of the main load lifting belt can be adaptively adjusted according to different centroids of lifted objects, so that the lifting appliance can lift the lifted objects with different centroids, meanwhile, in the process of converting a lifting load state into a no-load state, only the no-load lifting belt needs to be connected with the lifting beam and the lifting plate, and the lifting appliance is convenient to use. The position of the main load lifting belt does not need to be adjusted or the balancing weight does not need to be moved, the steps for converting the lifting state into the no-load state are few, time is short, efficiency is high, and lifting is more convenient.
本申请公开了一种吊具、起重机及吊装方法,属于吊装装备的技术领域。本申请吊具包括吊梁、连接件、多根主载吊带和多根空载吊带,主载吊带连接于吊梁和吊板,主载吊带与吊梁活动连接,以使主载吊带在吊梁上的位置可调,空载吊带连接于吊梁和吊板,且至少一个可拆卸连接,在吊板与起升机构连接的条件下,通过主载吊带起吊吊梁或通过空载吊带起吊吊梁。吊具在吊装时能根据被吊物质心的不同对主载吊带的位置做适应性的调整,使得吊具可以吊装具有不同质心的被吊物,同时,从吊载状态转变为空载状态的过程中,只需将空载吊带连接吊梁和吊板即可,不用调节主载吊带的位置或移动配重块,吊载状态转变为空载状态的步骤少、时间短、效率高、吊装更加方便。
