Problems solved by technology

[0002] As we all know, the structure of tower crane products is closely related to the needs of building construction. At present, the development of buildings in my country is tending to the development of high-rise super high-rise buildings, and the application of large-scale fabricated components is becoming more and more extensive. Solve the lifting problem, but for the port area, it is difficult to meet the requirements of such a large lifting capacity, lifting height and activity space

Abstract

The invention discloses a twin-tower type crane which comprises a primary tower body, a crane boom, an auxiliary tower body, a rubber-tyred chassis and a supporting frame, wherein the primary tower body is fixed on the supporting frame; the auxiliary tower body is fixed on the rubber-tyred chassis; a primary tower body standard segment, a primary tower body rotating mechanism and a lifting mechanism are arranged on the primary tower body; the crane boom is arranged at the upper part of the primary tower body; a winch drum, a pulley, a variable-amplitude trolley and an auxiliary tower body rotating mechanism are arranged on the crane boom; a lifting hook is arranged on the variable-amplitude trolley; an auxiliary tower body standard segment is arranged on the auxiliary tower body; and the auxiliary tower body rotating mechanism is connected with the auxiliary tower body. When the twin-tower type crane rotates, the primary tower body is fixed on the supporting frame without movement andprovides the rotating power, so that the crane boom and the auxiliary tower body do not infinitely rotate and only can rotate around the primary tower body within a larger circular arc; and the auxiliary tower body and a part of lifting weight are supported by the rubber-tyred chassis. The twin-tower type crane is suitable for large lifting capacity and large lifting height and has high strength and rigidity.

Description

technical field [0001] The invention relates to a double-tower crane, which belongs to the technical field of lifting and transportation. Background technique [0002] As we all know, the structure of tower crane products is closely related to the needs of building construction. At present, the development of buildings in my country is tending to the development of high-rise super-high-rise buildings, and the application of large-scale prefabricated components is becoming more and more extensive. Solve the lifting problem, but for the port area, it is difficult to meet the requirements of such a large lifting capacity, lifting height and activity space. Contents of the invention [0003] In view of the above-mentioned deficiencies, the present invention provides a double-tower crane, which solves the problems of lifting height, lifting load and working space through the common support of the main tower body and the auxiliary tower body. [0004] The present invention is ac...
