The invention discloses a gantry crane lifting appliance, and relates to the technical field of crane lifting appliances. The gantry crane lifting appliance comprises an auxiliary hanger plate, a mainhanger plate and clamp arms, wherein a lifting column is fixedly connected with the bottom of the auxiliary hanger plate, a cross beam is fixedly connected with the middle part of the clamp arm, anda moving groove is formed in the middle of the cross beam. By arrangement of the auxiliary hanger plate and the main hanger plate, the lifting appliance can be connected with two ropes, when the lifting appliance descends, the auxiliary rope is tensioned, the auxiliary hanger plate and the main hanger plate are combined and the clamp arm is in an opening state, when the lifting appliance ascends,the main rope is tensioned, the auxiliary hanger plate and the main hanger plate are separated and the clamp arm is clamped by a mechanical structure, energy consumption caused by driving parts and clamping parts is avoided, and the purpose of saving energy is achieved; by means of the cross beam, a telescopic rod can move transversely, the position of the telescopic rod can be changed after a crank drives a threaded rod to rotate, a clamped object is clamped by a rubber pad on the telescopic rod, and the purpose of improving clamping stability is achieved.

    本发明公开了一种门式起重机吊具,涉及起重机吊具技术领域,包括副吊板、主吊板和夹紧臂,所述副吊板的底部固定连接有升降柱,所述夹紧臂的中部固定连接有横梁,所述横梁的中部开设有移动槽。本发明通过设置副吊板和主吊板,能够使吊具连接两个绳索,在吊具下降的时候使副绳索拉紧,将副吊板和主吊板合并一起,使夹紧臂呈张开状态,在吊具上升的时候使主绳索拉紧,将副吊板和主吊板分开,利用机械结构将夹紧臂夹紧,避免了主动部件夹紧部件消耗的能源,达到了节能的目的,通过设置横梁,能够使伸缩杆进行横向移动,利用摇把带动螺纹杆旋转之后可以改变伸缩杆的位置,使伸缩杆上的橡胶垫将夹装的物品夹紧,达到提高夹装稳定性的目的。
