This utility model relates to the field of crane technology and discloses a novel lightweight gantry crane, including a crossbeam. A first threaded rod is rotatably connected inside the crossbeam, and a moving block is threadedly connected to the surface of the first threaded rod. A fixed pulley is fixedly installed at the rear end of the crossbeam, and a driving structure is provided on the upper surface of the crossbeam. This utility model utilizes a second motor. The rotation of the output shaft of the second motor drives the rotation of a first gear. The meshing between the first and second gears causes the first threaded rod to rotate inside the crossbeam, which in turn drives the moving block to move left and right. Because the fixed pulley and ball bearings share the weight of the load lifted from the lower part of the moving block, this device uses the first threaded rod to drive the movement. The cooperation between the fixed pulley and the slide rail, and the rotation of the ball bearings inside the mounting strip, converts sliding friction into rolling friction, thus enhancing the service life of the device.
