The invention discloses a novel double-trolley and double-lifting-hook tower crane. The tower crane comprises a cargo boom frame, a lifting assembly is fixedly installed in the cargo boom frame, a tower frame is fixedly installed at the bottom of the lifting assembly, a first variable-amplitude trolley is installed at the bottom of the tower frame in a sliding mode, and a second variable-amplitude trolley is installed on one side of the first variable-amplitude trolley in a sliding mode. According to the tower crane, the lifting assembly is fixedly mounted in the cargo boom frame, so that the mode that a first guide rail and a second guide rail are arranged on the cargo boom frame can be utilized, and meanwhile, the second variable-amplitude trolley and a second lifting hook are additionally arranged, a first lifting winding drum and a second lifting winding drum are arranged to be matched with a first variable-amplitude winding drum and a second variable-amplitude winding drum, and the winding drums driven by an output driving shaft of a speed reducing motor are changed, so that the single-action and linkage effects of the winding drums are formed, the single-action or linkage of the variable-amplitude trolley body and the lifting hook body is controlled, and hoisting of different double points at different intervals is realized.

    本发明公开了一种新型双小车双吊钩塔机,包括起重臂架,所述起重臂架的内部固定安装有起升组件,所述起升组件的底部固定安装有塔架,所述塔架的底部滑动安装有第一变幅小车,所述第一变幅小车的一侧滑动安装有第二变幅小车。本发明通过在起重臂架的内部固定安装有起升组件,能够利用通过在起重臂架上设置第一导轨和第二导轨双导轨的方式,同时增加一个第二变幅小车和第二吊钩,同时设置两个第一起升卷筒和第二起升卷筒搭配第一变幅卷筒和第二变幅卷筒,在通过改变减速电机输出驱动轴所带动的卷筒,形成卷筒单动和联动的效果,从而控制变幅小车本体和吊钩本体的单动或联动,实现不同双点不同间距的吊装。
