Problems solved by technology

[0003] When the cranes in the prior art are applied to large-tonnage cranes on engineering ships, due to the limitation of the working range, the crane needs to be combined with the luffing action to complete the operation. It is necessary to install the luffing mechanism on the crane, which increases the cost and the operation. Trouble, low work efficiency

Embodiment Construction

[0014] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0015] like figure 1 and figure 2 As shown, the marine electric cantilever crane of this embodiment includes a base 1 connected to the deck of the ship. A cantilever 2 is welded on the base 1. The cantilever 2 is in a right-angled structure. Elevating hoist 3 is located on base 1 and is also equipped with an electric rotary reducer 4 that controls the rotary work of the crane.

[0016] The electric hoist 3 is connected with the wireless button box through an electric signal.

[0017] During actual use, the electric lifting hoist 3 is activated through the button box, and the electric lifting hoist 3 can walk to the corresponding position. Easy to operate.

[0018] The above description is an explanation of the present invention, not a limitation of the invention. For the limited scope of the present invention, please refer to the clai...

Abstract

The invention relates to a marine electric cantilever crane. The marine electric cantilever crane comprises a base connected with a ship deck, wherein a cantilever is welded on the base; the cantilever is in a right-angle structure; an electric lifting hoist which slides along the cantilever is mounted at the bottom of the horizontal part of the cantilever; and an electric rotary speed reducer for controlling the crane to rotate to work is further mounted on the base. The marine electric cantilever crane has a compact and reasonable structure, is convenient to operate and can be widely applied to engineering ships; and the crane has high working efficiency, wide application range and long continuous working capability. The cantilever is a horizontal cantilever; when small-radius work needs to be carried out, only the electric hoist needs to be operated to walk to a corresponding position, and the troublesome operation that a marine crane in the prior art can be operated by lifting the cantilever is avoided; and the marine electric cantilever crane has a compact structure and small occupying area and is also suitable for fields with compacted spaces on the engineering ships.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a marine electric jib 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] When the cranes in the prior art are applied to large-tonnage cranes on engineering ships, due to the limitation of the working range, the crane needs to be combined with the luffing action to complete the operation. It is necessary to install the luffing mechanism on the crane, which increases the cost and the operation. Trouble, low work efficiency. Contents of the invention [0004] Aiming at the above-mentioned shortcomings in the existing production technology, the applicant provides a marine electric cantilever crane with a reasonable structure, thereby improving work efficiency and occupying a small area. [0005] The technical scheme adopted in the present invention is as follows...
