[0002] Beam lifting machines are widely used in the field of lifting and handling. Although the beam lifting machines currently developed in China can meet the basic movement requirements, some performance requirements cannot be met well, especially in the operation and maintenance of large beam lifting machines. When the staff need to transport the equipment to the beam or gantry, it is more difficult. The staff generally have to transport it through the ladder on the side of the beam lifting machine, or transport it by hoisting with a crane. When transporting through the ladder on one side of the beam lifting machine, the staff needs to repeatedly go up and down the gantry that is dozens of meters high, which is time-consuming and labor-intensive, and has high safety risks; when transporting by hoisting with a crane, the transportation cost of the crane is high, which causes great interference to the construction site and has high safety risks for personnel. For this reason, we propose a traction lifting device for beam lifting machines to solve the above problems. Utility Model Content
