The invention discloses a retractable crane for ships, and relates to the technical field of ship hoisting, the retractable crane comprises a rope adjusting mechanism, a self-adaptive labor-saving hydraulic mechanism, a self-adaptive winding mechanism, a hoisting auxiliary mechanism and a rotating mechanism; the rope adjusting mechanism comprises an upper bracket, a lower bracket, a vertical sliding rail, a screw rod and a stepping motor A; the lower end of the upper support is fixedly connected with the upper end of the lower support through welding. The upper end and the lower end of the vertical sliding rail are fixedly connected with the upper support and the lower support respectively. The upper end of the lead screw is rotationally installed in a rotating hole in the upper support, the lower end of the lead screw is rotationally installed in a rotating hole in the lower support, the upper end of the lead screw is fixedly connected with a motor shaft of a stepping motor A, and the stepping motor A is fixedly installed on an extension plate on the upper support; when the device is used, the rope shares the pressure of the hydraulic cylinder by adjusting the angle between the telescopic arm and the telescopic arm, so that the energy consumption is uniformly distributed, and the hydraulic cylinder is assisted to lift goods more easily.
