Problems solved by technology

[0003] The jib and balance arm of the common flat-top tower cranes on the market are directly connected to the slewing tower body, so that it is independent from the pointed tower crane, and it is impossible to change only the horizontal part without changing the vertical part. Next Convert a pointed tower crane into a flat tower crane on the construction site

Abstract

The invention discloses a hinge assembly of a flat-top tower crane. The main body structure of the hinge assembly of the flat-top tower crane is a steel structure which is formed by welding a square steel tube, a seamless steel tube, a formed square steel tube and a steel plate in a combined manner, wherein the square steel tube is manufactured by squaring of angle steel; the steel structure is fastened with a revolving tower body, a balance arm and a crane boom by a pin roll and an opening pin in a connected manner, respectively; and a transitional segment is a key part of the hinge assembly. The hinge assembly of the flat-top tower crane has the advantages of being high in efficiency, low in cost, good in safety, good in reliability, less in material dosage, light in weight and convenient to install.

Description

Technical field [0001] The invention belongs to an essential component of a flat-top tower crane, and is used to connect the vertical part and the horizontal part of the flat-top tower crane. Background technique [0002] With the continuous acceleration of the urbanization process, the transformation of large cities and the new construction of small and medium-sized cities, the market demand for tower cranes is increasing. Due to the increasing number of high-rise buildings in the city, due to the constraints of the construction site, the traditional pointed tower crane has been unable to meet the changing construction technical requirements. Due to its special structure, the flat-top tower crane has a pointed tower crane. The advantages that cannot be replaced: ①On the construction site of a group of towers, the height of the self-supporting is reduced, and the height of the tower cranes installed on the construction site can be reduced correspondingly, thereby greatly reducing...
