Marine crane is a special crane that performs transport operations in the marine environment, mainly used for transporting and transferring cargoes between ships and ships, or ships and shore, replenishing at sea, and placing and recovering underwater operating equipment and other important tasks.

Telescopic-knuckle Boom Marine Deck Cranes are powered by electric motors or diesel fuel, which 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 load. They are mainly used for general cargo loading and unloading, fishing nets loading and unloading, etc.

Working Principle

These mechanisms are coordinated by the control system and work together to complete the lifting task.
1. Lifting mechanism: most of them are composed of an angling system and a winch; there are also lifting and lowering heavy objects through the hydraulic system.
2. Running mechanism: generally consists of a motor, a reducer, a brake, and wheels, used for longitudinal horizontal transport of heavy loads or adjusting the working position of the crane.
3. Luffing mechanism: By changing the amplitude of the lifting arm to meet the lifting needs of different distances, the knuckle boom crane may have two luffing mechanisms to make its operation more flexible.
4. Slewing mechanism: enables the lifting arm to rotate around the slewing center, thus adjusting the lifting direction of the heavy load.

Application

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 harbours, 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.

Important

Cooperation

We start from meeting each other, visiting factories, discussing requirements, giving solutions, confirming orders, discussing details, and completing deliveries. We became not only business partners but also friends in life. It was a pleasant and meaningful journey.

FAQ:    

1. Are you a manufacturer?
 Yes, we operate a factory staffed with skilled technicians on-site, complemented by our trading company.

2. Are your products customized?      
 Yes, because of the different working conditions, all our products are customized depending on detailed requirements! So if you give us more information about the lift capacity, span, lift height, power source, and other specs, we will give you a very quick quote!   

3. What information should I provide when inquiring?    
The more information you provide, the more accurate solution we can prepare for you! The information, such as the lifting capacity, span, lifting height, power source, or other special features you give us, will be appreciated. It would be better if we had drawings.

4. What are the MOQ and payment terms?
Our MOQ is just one set, and we accept T/T and L/C at sight, with other terms open for negotiation.

5. How do you guarantee the quality?
Before shipment, we will do a series of inspections and tests, and have a detailed tracking report. You can also go through the domestic testing company agent testing, or you personally send a delegation to track the testing process, it is ok.

6. How can we install the crane?     
Our senior engineer can be on your side to provide the installation guide service and training.

7. Can you provide the serious lifting tools?     
Sure, we can provide any lifting tools such as lifting sling belts, lifting clamps, grab buckets, Spreader beams, magnets, or other special tools as your requirement!
