Product Description

Deck crane or ship crane, is a type of large deck machinery on board ships, mainly used for loading and unloading cargo.This equipment is easy to operate, flexible in operation, and can adapt to the operation of various types of goods. Therefore, it has been widely used in ship operations. Ships equipped with cranes are popular among shippers and lessors in the shipping market. The structure of a deck crane mainly includes a base, rotating rod, boom, wire rope, and pulley system. According to the form of the boom, the crane can be divided into three types: straight arm, telescopic arm, and folding arm.

Marine Deck Crane, by electric or electro-hydraulic control,can rotate 360 degrees and can change amplitude within the length of the boom. Full hydraulic drive, electric motor, hydraulic pump, hydraulic motor, valve block, fuel tank, reel and other components are arranged in a cylindrical rotating barrel, the internal space structure is compact, so that the ship has more deck area can be used.
There is no tedious preparation work before Marine Deck Crane operation. The hook can be attached with a grab bucket to load and unload bulk goods, which has good adaptability to the goods and is widely used.

Telescopic arm type:
The telescopic arm cranes offer a diverse product line for application in the Luxury Yacht, Oceanographic, Workboat, Oilfield, Coast Guard etc. These cranes can also be further customized for use in these most demanding of work environments.
All of the cranes in the Telescopic Boom line offer several key features that make them powerful solutions for the marine work environment. The most notable of these features include: Extended boom reach with the dexterity for accurate, safe, and efficient material handling.It can be extended and retracted as needed to adapt to different lifting distances and heights, thereby improving work efficiency; Enabling the crane to perform lifting operations in narrow spaces and improving operational flexibility; Adopting advanced engines and hydraulic systems reduces noise and energy consumption.
 

Straight arm type:
As a common type of marine lifting equipment, the marine straight arm crane consists of three main mechanisms: lifting, slewing, and slewing. This makes the operation more intuitive and simple, easy to operate and maintain, and reduces maintenance costs; The rotary hydraulic system can achieve 360 degree full rotation, with flexible operation and the ability to adapt to different working environments and cargo loading and unloading needs; In the design and manufacturing process, stability and safety were fully considered, and advanced technologies such as closed design and large-diameter outer tooth manganese steel turntable were adopted to ensure smooth operation even in harsh sea conditions.
 

Folding arm type:
The design of the folding arm allows it to flexibly extend and fold within a limited space, adapting to narrow installation spaces;
Lightweight, but capable of lifting large masses, adaptable to complex layouts on ships, able to lift goods from multiple angles and directions, and improve operational efficiency;
Adopting special anti-corrosion treatment and sturdy structural design, it can resist the erosion of seawater and harsh marine climate conditions. Having good stability and resistance to wind and waves;
Suitable for tasks such as inland waterway transportation, sea supply, and the deployment and recovery of underwater equipment, capable of stable operation in complex environments.
