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, used primarily 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.
A telescopic folding jib crane, also known as an electro-hydraulic telescopic foldable boom crane, is a lifting equipment that uses electric power to drive the hydraulic system to realize the telescopic and folding action of the jib.
Design
We can design and produce cranes according to the operational scenarios and specific requirements, accept non-standard customization, and allow customers to choose the required functions according to their requirements.

Note: 1. Larger load capacity crane not listed herein can be offered on request;
2. Explosion-proof requirements in the inquiry.
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, and telescopic folding jib crane.
2. Divided according to operational areas (Classification Society Code Naming)
- Ordinary cranes(ship cranes): 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.
