Orbit type gantry crane

Abstract

The present invention relates to an orbit type gantry crane, comprising a crossbeam, an outrigger, a saddle beam, a hoisting mechanism and an orbit hanging trolley. The hosting mechanism is installed at the saddle beam. A steel wire led out by the hoisting mechanism is connected with a pulley at an orbit hanging crane hanging tool through a relevant pulley group. The hoisting mechanism is not installed at the trolley but is installed at the saddle beam at the lower part of the outrigger, thus the trolley has simple structure and greatly reduced weight, and the manufacturing technology of the trolley is simplified greatly; at the same time, because the installation position of the hoisting mechanism is placed at the saddle beam which is close to the ground, the hoisting mechanism is very convenient for maintaining; in addition, a novel single beam structure is adopted to the crossbeam, and a double-beam structure in the prior art is not adopted, so the whole crane weight is reduced greatly at the same time, and the borne pressure of the wheels of the crane is reduced greatly.

Description

technical field [0001] The present invention relates to port container crane, more specifically, relates to a type of gantry crane locomotive. Background technique [0002] The strong demand for world container transportation and the continuous growth of container port throughput have put forward newer and higher requirements for container handling technology and equipment. Therefore, it is urgent to develop and design a high-efficiency shoreside container handling system to meet the needs of large-scale and high-speed ships. Demands on crane productivity. Rail-mounted gantry crane is a kind of container loading and unloading technical equipment. See Figure 1. It generally includes girder 10, outrigger 20, rail crane trolley 50, and lifting mechanism 40. Rail crane trolley 50 slides on the height of the crane. The spreader 60 of the crane is connected with the steel wire rope through the pulley block, and the spreader 60 implements the transportation of the goods. When the ...

AI Technical Summary

Problems solved by technology

[0004] 1. The hoisting mechanism 40 is installed on the rail crane trolley 50, which greatly increases the weight of the rail crane trolley 50, making the structure and manufacturing process of the rail crane trolley 50 very complicated

[0005] 2. The girder 10 of the rail-mounted gantry crane is a double-girder structure, and the legs 20 support the double girders of the girder 10, which will increase the weight of the whole machine and the corresponding cost will also increase
