Knuckle Boom Marine Crane

Degree of Rotation :0-400°
Certificate: CCS, ABS, BV, RS, DNV, LR, NK, ISO9001, CE,
A marine crane is a special crane that performs transport operations in the marine environment. It is mainly used for transporting and transferring cargo between ships or ships and shore, replenishing at sea, placing and recovering underwater operating equipment, and other important tasks.
Knuckle Boom Marine Deck Cranes have double arms powered by electric motors or diesel fuel. These arms drive hydraulic cylinders to extend and retract, controlling the movement of the lifting boom to achieve cargo transfer. Many knuckle boom cranes are fully cylinder-driven and can telescope with a load. They are mainly used for general cargo loading and unloading, fishing net loading and unloading, etc.
Working Principle
The control system coordinates these mechanisms and works together to complete the lifting task.
1. Lifting mechanism: most of them are composed of a hanging system and a winch, there are also lifting and lowering of heavy objects through the hydraulic system.
2. Running mechanism: generally consists of motor, reducer, brake, and wheels, used for longitudinal horizontal transport of heavy loads or adjusting the working position of the crane.
3. Luffing mechanism: To make its operation more flexible, the knuckle boom crane may have two luffing mechanisms, changing the amplitude of the lifting arm to meet the lifting needs of different distances.
4. Slewing mechanism: enables the lifting arm to rotate around the slewing center, thus adjusting the lifting direction of the heavy load.
Applications
Service Cranes, Supply and Cargo Cranes, Fishing Cranes, Grab Cranes
The folding, telescopic, and articulated features of the jib are especially suitable for workplaces with limited space, short lifting distances, and frequent operations, such as harbors, wharves, cargo ships, passenger ships, railway stations, power stations, workshops, and so on.
We can design and produce different cranes according to different requirements and accept non-standard customization.
