Preferably, the sheave assembly at least includes a sheave installation beam installed on the longitudinal beam, the sheave installation beam has a back-shaped structure with upper and lower ends open, and the sheave installation beam is installed with a rope wheel.

The utility model has the advantages of setting oblique supports on the car frame and the longitudinal beams and enhancing the stability. Compared with the existing technology, the utility model includes at least two car frames arranged at intervals before and after, and arranged in left and right rows between the two car frames. There are multiple longitudinal beams, and also includes a car platform for carrying. The lower end surface of the car platform is fixedly installed on the bottom of the car frame. Two load-bearing beams are connected with diagonal stay rods on the load-bearing beams, and the diagonal stay rods are fixedly connected with the car frame. Diagonal support rods are respectively arranged on the left and right sides of the car frame. The beam is fixedly connected. The utility model can strengthen the stability of the longitudinal beam and the car frame by being provided with the inclined support rods, and effectively strengthen the overall strength.
