The invention aims to provide a platform-retractable hydraulic lift, which mainly comprises three parts, i.e. a chassis, a connecting rod mechanism and a manned platform. A hydraulic driving mode is adopted, the basic working principle is that the hydraulic list moves to a specified position, motive power is provided by a motor to drive a hydraulic pump, and then a hydraulic cylinder works to further drive the connecting rod mechanism to be unfolded to lift the platform. After the platform reaches a specified operation height, power is provided by the hydraulic motor according to operation needs, then gears and a rack are driven to rotate to further extend the platform, and meanwhile, a counterweight platform is driven by the gears and the rack to reversely extend. According to the platform-retractable hydraulic lift, the movement of the whole lift is reduced, the problem of limited horizontal operation space of various kinds of lifting operation in an enterprise is effectively solved, and the operation range of an operator is widened; the counterweight platform driven by the gears and the rack reversely extends, so that center-of-gravity shift is effectively prevented, and the safety and the stability of the manned platform are ensured.
