Technical Field

the invention relates to the field of buildings, in particular to a lifting device of a construction machine.

Background

The lifting device is a hoisting machine for vertically transporting people or objects. The device is widely applied to high-altitude installation, maintenance and other operations besides being used for conveying goods with different heights. The characteristic that the lifting device freely goes up and down is widely applied to municipal maintenance, cargo transportation at wharfs and logistics centers, building decoration and the like at present, the working height space is changed, and the lifting device has the advantages of light weight, self-walking, electric starting, self-supporting legs, simplicity in operation, large working area, capability of crossing obstacles to perform high-altitude operation and the like, and can freely rotate for 360 degrees.

However, in high-altitude operation, safety is very important, so that the requirement on the firmness of the traction rope is high, and once the traction rope is scattered, the lifting device falls, which can result in immeasurable consequences.
