Description

Low-altitude adjustable cable crane Technical Field The utility model relates to the field of cable cranes, in particular to a low-altitude adjustable cable crane. Background The cable hoisting construction method is a method for hoisting prefabricated parts into a bridge through a cable system. The cable hoisting system can be divided into four basic components according to the working property, namely a main cable, a working cable, a tower and an anchoring device. The working rope comprises a lifting rope, a traction rope, a buckling rope and the like. The working principle of cable hoisting is that the main cable is used for bearing the hoisting weight and serving as a running track of the sports car, and the hoisting device and the traction device on the sports car of the main cable are used for hoisting, lifting, transporting and installing the components. Through retrieving, at the patent document of bulletin number CN217102762U, a low altitude angle adjustable cable crane is disclosed, and the cable crane includes hoist mechanism 1 and is located hoist and mount frame 2 of hoist and mount mechanism 1 below, and hoist and mount frame 2's below is equipped with hoist and mount rope 3, needs to adjust the transportation angle of article, initiatively adjusts the transportation angle of article, improves the security and the stability of transporting.
