Abstract

The invention provides a stable motion type tower crane which comprises a base, a tower body, a rotating table, a tower top, a cargo boom, a balance arm and a hoisting mechanism, wherein the hoisting mechanism comprises a walking frame, rollers, a mounting box, a speed adjusting device, a haulage cable, a balancing device and a hook; the rollers are mounted at the upper end of the walking frame; the mounting box is mounted at the lower end of the walking frame; the speed adjusting device is mounted in the mounting box, and comprises a wire guide roller, a C-shaped brake rack and a plurality of brake blocks; the balancing device comprises two conical heavy blocks, a connecting rod, a rotary disc and a plurality of wind shields; the hook is mounted at the lower end of the balancing device; the haulage cable penetrates through the wire guide roller to be connected with the upper end of the balancing device; and a moving track for allowing the rollers to move is arranged on the balance arm. The stable motion type tower crane is convenient to use, and the stability and safety of the tower crane are effectively improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a motion-stabilized tower crane. Background technique [0002] Tower crane (tower crane) referred to as tower crane, also known as tower crane, originated in Western Europe. A rotating crane with the boom mounted on the top of a tall tower. The working space is large, and it is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes tower body, jib and base etc. However, the current tower cranes are difficult to ensure the stability of the transported objects due to high-altitude operations, and because the weight of the transported objects varies greatly, the speed of object transportation is also difficult to control. Contents of the invention [0003] Based on the technical problems ex...
