Abstract

The invention discloses a large-tonnage platform crane, which is composed of a column, an operating room, a beam, a hoist, a pulley block, a steel wire rope, a hook and an electrical control system. The two columns are at the same height, and the height of the two columns near the dock door is higher than the height of the two columns away from the dock door. The two ends of the beam are respectively set on the two opposite columns of the same height. The cross-section of the beam is box-shaped and adopts a variable-section welding structure. There is a set of lifting mechanisms on both sides of each beam. The present invention has the advantages of large lifting tonnage, large span, high lift, many lifting points, stable lifting and translation, adopting a beam translation structure, and can adapt to the requirements of various lifting points. features.

Description

technical field

[0001] The invention belongs to the technical field of hoisting equipment, in particular to a large-tonnage crane used for building offshore platforms. Background technique

[0002] Due to the relatively large weight of offshore platforms, the current construction of offshore platforms generally adopts segmented construction, using small cranes or offshore floating cranes to hoist in segments, and then assembled and welded into one. Low, high risk, at the same time, due to the complex offshore operation environment, the segmental hoisting is greatly affected by the environment, and the hoisting is prone to inadequacy when the weather conditions are complex, making the mutual positioning of the segmented platforms inaccurate, causing troubles to the construction, and this Due to the many welding points of the built platform, the welding quality cannot be guaranteed, which affects the overall quality of the platform, and the construction period and construction...
