Problems solved by technology

[0003] Small ships in the prior art, especially some fishing boats, have a lot of equipment on board this type of ship, and the installation space for the crane is limited. This type of ship also has higher requirements for the crane, and has a longer working radius. It should be small, so the previous telescopic cranes are difficult to meet the use requirements, the use flexibility is poor, and the work efficiency is affected

Abstract

The invention relates to a marine multi-section arm telescopic crane. The crane comprises a base seat, a tower body is arranged on the bottom seat, an arm support is hinged on the top part of the tower body, wherein the arm support is composed of a plurality of sections of arm supports, a luffing oil cylinder is arranged between one side of the tower body and the bottom of the arm support, the bottom of the arm support is provided with a lifting winch, the lifting winch is connected to a lifting hook through a steel wire rope; the top part of the arm support is provided with a plurality of telescopic oil cylinders, and a plurality of swing oil cylinders is arranged on the bottom seat. The marine multi-section arm telescopic carne has the advantages of impact and reasonable structure and simple operation, adopts a multi-section arm telescopic movement mode, which is controlled by a plurality of telescopic oil cylinders, thus reduces the size of the arm support, and satisfies the long-distant hoisting function.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a marine multi-section telescopic crane. Background technique [0002] A marine crane is a large deck machinery on a ship, and it is a device for loading and unloading cargo on a ship. [0003] Small ships in the prior art, especially some fishing boats, have a lot of equipment on board this type of ship, and the installation space for the crane is limited. This type of ship also has higher requirements for the crane, and has a longer working radius. It needs to be small, so the traditional telescopic cranes are difficult to meet the requirements of use, and the flexibility of use is poor, which affects work efficiency. Contents of the invention [0004] Aiming at the shortcomings in the above-mentioned existing production technology, the applicant provides a marine multi-section boom telescopic crane with reasonable structure, so that the multi-section boom is teles...
