Four-link Portal Crane is widely used in ports, docks, yards and other places to complete the loading, unloading and transshipment operations of ships and vehicles.
Product overview:

The Four - link Portal Crane is a highly efficient and versatile piece of heavy - duty machinery that has found extensive application across a variety of industrial landscapes, with ports, docks, and yards being among its primary arenas of operation.


In ports, which serve as crucial gateways for global trade, the Four - link Portal Crane plays an indispensable role. As large cargo ships arrive, brimming with goods from around the world, the crane is quickly mobilized. Its unique four - link mechanism allows for a high degree of precision and control during the loading and unloading processes. The crane's sturdy boom, supported by the four - link system, can reach far out over the ship's deck. With specialized lifting attachments, it can securely grasp different types of cargo, such as standard shipping containers, pallets of consumer goods, or even large pieces of industrial equipment. Once the cargo is firmly in place, the crane smoothly hoists it up and transfers it to the dock. This seamless transfer ensures that the goods can be efficiently processed for further distribution, either to storage facilities within the port or directly onto waiting trucks for land - based transportation.


Docks, whether they are small - scale local operations or part of larger port complexes, also benefit greatly from the presence of Four - link Portal Cranes. For smaller vessels like fishing boats or coastal barges, these cranes are used to unload fresh catches or local supplies. Their ability to handle diverse cargo weights and sizes makes them ideal for such operations. The crane can precisely position the cargo onto the dock, facilitating easy sorting and transfer to storage areas or vehicles. During the loading process, it can carefully load cargo onto these smaller ships, ensuring that they are properly equipped for their voyages.

Product Details
Application Scenario

Four-link Portal Crane is widely used in ports, docks, yards and other places to complete the loading, unloading and transshipment operations of ships and vehicles. Its design, manufacture and inspection implement DIN, FEM, IEC, AWS, GB and other domestic and foreign advanced standards and the latest national standards. 


Four-link Portal Crane is divided into two types: single boom and four-link boom type according to the structure of the boom. The four-link portal cranes use the combined arm frame system to achieve the horizontal movement. It has the characteristics of small horizontal gap, stable variable amplitude, and low power consumption.

Key Applications & Use Cases

  1. Ports & Shipping Terminals – Efficiently moves shipping containers, heavy cargo, and bulk materials with high precision.

  2. Construction Sites – Lifts steel beams, prefabricated structures, and machinery with superior stability.

  3. Warehouses & Logistics Centers – Handles pallets, large equipment, and stored goods with a wide-span gantry design.

  4. Manufacturing Plants – Supports assembly lines, heavy component transfers, and industrial production with smooth load control.
