The invention provides a lifting appliance lifting device for a metal pipe. The lifting appliance lifting device comprises a lifting appliance and more than two groups of lifting mechanisms, the lifting mechanism comprises a fixing seat and a lifting rod, the lifting rod is a long-strip-shaped assembly extending in the vertical direction, the lifting rod is arranged in a limiting mechanism of the fixing seat in a penetrating mode and is in relative sliding fit with the fixing seat in the vertical direction, and the lower end of the lifting rod is fixedly connected with the lifting tool; the first driven chain wheel is fixedly arranged at the upper part of the lifting rod; the second driven chain wheel is fixedly arranged at the lower part of the lifting rod; the driving chain wheel, the first driven chain wheel and the second driven chain wheel are arranged in a coplanar mode in the vertical direction. The tensioning mechanism is arranged on the other side, opposite to the lifting rod, of the driving chain wheel; the tensioning mechanism is further provided with a first pull rod and a second pull rod. One end of the chain is fixedly connected with the first pull rod, and the other end is fixedly connected with the second pull rod. According to the invention, the phenomena of horizontal movement, low end and high end during hoisting of the metal pipe can be avoided; the device is simple in structure, reliable in performance and easy to popularize and use.
