Product Description

Fixed Boom Marine Cranes

More affordable and easier to maintain, The fixed boom pedestal crane is more durable and has less moving parts. The fixed boom pedestal crane is the perfect solution for standard, ordinary lifting & handling needs. A fixed boom marine crane works faster and is mostly used to transport groceries and smaller, more ordinary lifting & handling purposes.
 

Detailed Photos

This crane is hydraulically driven,maximum capacity is 200t/m.the control can be either manual or wireless remote control All hydraulic components used are from internationally renowned brand.

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.
