Problems solved by technology

[0004] At present, the lifting work of crawler cranes is mainly through the luffing steel wire rope and the rear counterweight to ensure the smooth lifting of the boom. In this way, it is necessary to provide sufficient pulling force and counterweight, which brings great difficulties to assembly, use and cost.

Abstract

The invention provides hoisting equipment and relates to the technical field of hoisting of cranes. The hoisting equipment comprises a crane and a lifting device, wherein the crane comprises a first main body, a traction mechanism and an arm frame, the traction mechanism is fixed to the first main body, one end of the arm frame is hinged to the first main body, a movable end of the traction mechanism is connected with the arm frame and used for lifting a hoisting end of the arm frame, the movable end of the lifting device is used for lifting the arm frame, the movable end of the lifting devicecan move in the vertical direction so that the arm frame can be driven by the lifting device to be lifted. The equipment is advantaged in that the traction mechanism and the lifting device act on thearm frame together, the arm frame can be lifted by both the traction mechanism and can be lifted by the lifting device, two strands of force act on the arm frame at the same time to drive the arm frame to rotate upwards around the first main body, so that a lifting end of the arm frame is lifted.

Description

technical field [0001] The invention relates to the technical field of crane jib, in particular to a lifting device. Background technique [0002] Crawler cranes are widely used in petroleum, chemical industry, electric power, metallurgy and large buildings, bridges, shipbuilding and other industries for hoisting operations due to their advantages of walking with load, wide operating range, strong lifting capacity, and high construction site efficiency. [0003] In recent years, in order to meet the market demand, large-tonnage crawler cranes have developed very rapidly. Large-tonnage crawler cranes have large lifting capacity and high height. Therefore, the boom length of large-tonnage crawler cranes is very long, and the self-weight of the boom is very heavy. In the process of raising the boom, it is necessary to provide sufficient pulling force and counterweight to lift the boom. [0004] At present, the lifting work of crawler cranes is mainly through the luffing steel ...
