The invention discloses a chassis supporting structure of hoisting machinery, comprising a chassis and a cargo boom. First hydraulic rods are fixedly mounted at the two ends of the chassis; second hydraulic rods are fixedly mounted at the bottoms of one ends of the first hydraulic rods; a landing support base is fixedly mounted at the top of the left end of the chassis; a chute is formed in one end of the landing support base; the landing support base is slidably connected with a landing support plate; and a buffer spring is fixedly mounted at the bottom of the landing support plate. In the invention, the first hoisting hydraulic rods and the second hoisting hydraulic rods drive the cargo boom to move at the same time, so that the cargo boom rotates more quickly in a more labor saving mode; meanwhile, the first hoisting hydraulic rods and the second hoisting hydraulic rods are "spare tires" for each other; and when one hoisting hydraulic rod breaks down, the other hoisting hydraulic rod can drive the cargo boom, the use of the crane cannot be affected, and the left end of the cargo boom cannot be suddenly lowered to avoid dangers.

    本发明公开了一种起重机械的底盘支承结构,其技术方案是:包括底盘和起重臂,所述底盘两端固定安装第一液压杆,所述第一液压杆一端底部固定安装第二液压杆,所述底盘左端顶部固定安装着陆支撑座,所述着陆支撑座一端开设有滑槽,所述着陆支撑座滑动连接着陆支撑板,所述着陆支撑板底部固定安装缓冲弹簧,本发明中第一起重液压杆和第二起重液压杆同时带动起重臂运动的方式,使得起重臂的旋转更为快速,更省力,同时第一起重液压杆和第二起重液压杆互为“备胎”,当其中一个发生故障时,另一个还可以驱动起重臂,不会影响起重机的使用,并且不会致使起重臂左端骤降,避免危险的发生。
