Crane (used to refer to smaller tonnage), also known as ship cranes, refers to the maritime environment to perform transport operations of a special crane, mainly used for ship to ship, ship and shore cargo transport, transfer, supply at sea, underwater operation equipment, such as the launch and recovery of important tasks.
Telescopic folding jib crane, also known as electro-hydraulic telescopic foldable boom crane, is a kind of lifting equipment which uses electric power to drive the hydraulic system to realize the telescopic and folding action of the jib.
Main components:
1. Boom system: comprising telescopic and folding boom sections made of high-strength materials to withstand the loads involved in lifting.
2. Hydraulic system: It contains hydraulic pumps, hydraulic cylinders, hydraulic valves and other components, which are responsible for providing power and controlling the movement of the boom.
3. Electric drive system: usually consists of an electric motor, controller, etc., which provides power to the hydraulic system.
4. Lifting mechanism: hooks/spreaders, wire ropes, etc., for attaching and lifting heavy loads.
5. Slewing mechanism: It enables the boom to rotate horizontally, increasing the flexibility of work.
6. Control system: including operating handle, control panel, etc., for the operator to control the crane's various actions and functions.
7. Pedestal: Fixed on the deck, etc., to increase the stability and carrying capacity of the crane.
Features:
Telescopic folding cranes are compact and can be easily installed on all types of vessels; the contraction and folding of the lifting arm makes them light and flexible, taking up little space, and with a large lifting capacity and a wide range of working radius.
Applications
Collapsible telescopic boom cranes are particularly suitable for use on ships, oil rigs and other offshore platforms where space is limited and heavy lifting is required.

Classification of cranes:
1, According to the type of boom can be divided into: straight jib crane, folding jib crane, telescopic crane, telescopic folding jib crane.
2. Divided according to operational areas (Classification Society Code Naming)
- Ordinary cranes(ship crane): operate in ports or sheltered waters where there is no significant movement of the ship under wave action.
- Offshore cranes: Cranes used on ships or platforms that operate in open waters offshore. The sea conditions in these waters can cause significant movement of the vessel or platform.
- Heavy cranes: SWL >160T
3. Divided according to service categories: service cranes, grain and cargo lifting cranes, fishing cranes, platform cranes, grab cranes and so on.
We can design and produce cranes according to the operational scenarios and specific requirements, accept non-standard customization, and customers can also choose the required functions according to their requirements.

Working Principle
Folding knuckle boom marine deck crane provides power through the electric motor, drives the hydraulic pump to generate pressure oil, and then pushes the hydraulic cylinder to realize the extension, contraction and folding of the boom, so as to complete the lifting work of heavy objects.

Certification
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.Is your products customized?
Yes, because of the different working condition, all our products are customized depending on detail requirement! So if you give us more information about the lift capacity, span, lift height, power source and other specials, we will give you a very quick quote!
3.What's the information should I provide when inquiry?
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 specials you give us will be more 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 through the domestic testing company agent testing, or you personally or send a delegation to track the testing process, it is ok.
6.How can we install the crane?
Our senior engineer can be 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 belt, lifting clamp, grab bucket, Spreader beams, magnet or other specials as your requirement!
