The structure of the marine folding crane mainly includes the following key parts:
Boom: The boom is the main part of the crane and is used to extend to lift heavy loads. The boom of the marine folding crane is designed to be foldable to save space and adapt to different working environments.
Hydraulic system: Marine folding cranes are usually equipped with closed hydraulic systems for driving mechanisms such as lifting, luffing and slewing. The design of the hydraulic system includes the pumping station system, the reversing valve system, the hoisting system, the luffing system, the slewing system and the operating system. The closed hydraulic system can effectively improve the efficiency of the system, reduce the vibration and impact of the mechanical structure, and recover the potential energy of the lifting weight.
Luffing Cylinder: Luffing cylinder is used to adjust the angle of the boom to adapt to different lifting heights and working ranges.
Collision avoidance system: Some marine folding cranes are equipped with collision avoidance systems to protect the crane and the working environment.
Surface treatment: In order to adapt to the harsh marine environment, the surface treatment of the marine folding crane needs to be corrosion resistant.
Column: The column is the vertical support structure of the crane, which supports the weight and lifting load of the entire crane.
Hook: The hook is the end effector of the crane and is used to connect and lift heavy loads.
Sheave: Sheave is used to change the direction of the wire rope and reduce the bending stress of the wire rope to improve the lifting efficiency.
Control system: The control system includes electro-hydraulic drive, which is used to operate various actions of the crane, such as lifting, luffing and slewing.
Lifting winch: The lifting winch is installed on the main boom and is equipped with a hydraulic motor, reducer, brake, bearing seat, reel, frame, etc. When the brake is not in working condition, it is usually closed to ensure safety
.
Slewing ring: Slewing bearing is suitable for axial force, radial force, overturning moment and other loads, and can bear the above loads smoothly and reliably.
Swing Ring: The swing ring is the part that connects the boom to the column, allowing the crane to rotate within the horizontal plane to cover a wider work area.
Slewing mechanism: The slewing mechanism is installed on the tower body and is used to control the slewing speed of the crane.
These structural components work together to enable the Marine Folding Crane to carry out lifting operations efficiently and safely in marine environments.
.
As a result of their sophisticated crane geometry work is effortless with articulated boom cranes. They make full use of their strengths and flexibility when loading and unloading equipment. Due to their compact construction they can easily be accommodated on every type of vessel especially where space is limited. Adding various features and options make the articulated boom marine crane a multi-functional tool. YFM articulated boom cranes can be designed according to offshore rules and regulations.
Our company is specialized in making marine cranes, and has 12 years of experience so far. There are various types of marine cranes, marine cranes, and dock cranes. If you are not satisfied with the existing one, you can also customize it according to your requirements. If you have any needs, please feel free to contact us.
