Abstract

The utility model discloses combined lifting equipment, which can be used for lifting heavy component equipment by using a combination of a roller, a fixed pulley and a movable pulley through a lifting rope, and is convenient to install above a position to be lifted. A combined lifting device comprises a first roller assembly. The first roller assembly comprises a traverse unit, a lifting rope is wound on the traverse unit, and the traverse unit is connected with a first speed reducer for controlling rotation; the device further comprises a lifting support. The lifting support is installed at the position needing to be lifted, a first pulley assembly is installed at one end of the lifting support and comprises a first fixed pulley, and the lifting rope penetrates through the first fixed pulley in a surrounding mode. A first driving assembly is mounted on the rear side of the first pulley assembly; the first driving assembly comprises a second speed reducer, a first winding drum is installed on an output rotating shaft of the second speed reducer, and the lifting rope penetrates through the first winding drum in a surrounding mode. A second pulley assembly is installed on the rear side of the first driving assembly and comprises a second fixed pulley, and the lifting rope penetrates through the second fixed pulley in a surrounding mode.
