The invention relates to the technical field of aerial work machinery, in particular to a scissor type aerial work platform and a scissor lifting assembly thereof, the scissor lifting assembly comprises a scissor frame, a lifting mechanism and a weighing mechanism, a rotary connecting rod is transversely arranged on the scissor frame in a penetrating mode, and the rotary connecting rod can rotate around the central axis of the rotary connecting rod; the hoisting mechanism comprises a driving base and a push rod extending out of the driving base; the lower end of the driving base is rotationally connected with the shear fork frame, and a rotary sleeve is fixed to the extending top end of the push rod and fixedly sleeves the periphery of the rotary connecting rod; the weighing mechanism is arranged on the rotary sleeve and the rotary connecting rod and can measure the bearing capacity of the rotary connecting rod. The weighing mechanism can measure the bearing capacity of the rotary connecting rod, a manufacturer determines that the maximum bearing capacity of one rotary connecting rod corresponds to the maximum bearing capacity of the shear fork frame, and the weighing mechanism can enable a user to see whether the actually-measured bearing capacity exceeds the specified maximum bearing capacity or not in a manner of externally connecting a display screen and the like. And safety accidents caused by overload are avoided.
本发明涉及高空作业机械技术领域,具体涉及一种剪叉式高空作业平台及其剪叉起升总成,剪叉起升总成包括剪叉架、起升机构和称重机构,剪叉架上横向穿设有回转连杆,回转连杆能够绕自身中心轴线转动;起升机构包括驱动底座、从驱动底座中伸出的推杆;驱动底座下端与剪叉架转动连接,推杆的伸出顶端固定有回转套筒,回转套筒套设固定在回转连杆外围;称重机构设置在回转套筒和回转连杆上,并且能够测出回转连杆的承重量。称重机构能够测出回转连杆处的承重量,厂商确定有一个回转连杆处的最大承重量,对应到剪叉架的最大承重能力,称重机构可以通过外接显示屏等方式让使用者看到实际测出的承重量是否超出规定的最大承重量,避免超载引起安全事故。
