The invention discloses a shear-fork type lifting device for an aerial work platform. The shear-fork type lifting device for the aerial work platform is characterized by comprising a shear-fork type lifting structure and a work platform. The shear-fork type lifting structure comprises upper shear-fork units, lower shear-fork units and a lifting oil cylinder. The multiple upper shear-fork units are sequentially hinged from bottom to top, and the multiple lower shear-fork units are sequentially hinged from bottom to top. A wiring pipeline structure is arranged on the shear-fork type lifting structure. The wiring pipeline structure comprises wiring hard pipes, wiring flexible pipes and control wires used for controlling the work platform. The wiring hard pipes are fixed on the shear-fork type lifting structure. On the premise of guaranteeing the lifting height, by reducing the thickness of the upper shear-fork units, the weight borne by a lifting hydraulic cylinder is lowered, the efficiency and the safety of a device are improved, and the control wires can be well protected in the wiring hard pipes.
