Mobile four link portal crane
Working condition of four link traveling portal crane Four link fixed portal crane mainly consists of steel structure, lifting mechanism, luffing mechanism, slewing mechanism, long traveling mechanism, spreader device, electrical equipment and other necessary safety and auxiliary equipment. The four-link portal crane adopts a combined boom system to realize the horizontal movement of goods during the luffing process, and has the characteristics of small horizontal drop, stable luffing and low power consumption.
APPLICATIONS
Port Handling
Core application: Four-link gantry cranes play a vital role in ports for loading and unloading cargo from ships. Its unique combination boom system enables horizontal movement of cargo with smooth luffing and small horizontal drop, making it ideal for efficient operations in port environments.
Advantage: The four-link structure enables the crane to maintain high stability and safety during loading and unloading, while reducing power consumption and improving operational efficiency.
Terminal operations
Widely used: In addition to ports, four-link gantry cranes are also commonly used in various types of terminals, such as cargo terminals, container terminals and so on. In these places, cranes need to frequently carry out cargo loading, unloading, transshipment and other operations, the four-link structure can meet the needs of these complex and efficient work.
Functional characteristics: through the synergistic effect of the four links, the crane can easily cope with various shapes and weights of goods, to ensure that the loading and unloading process is carried out smoothly.
Yard Management
Important tool: In yard management, four-link gantry cranes are used to unload cargoes from transportation means (e.g. trucks, trains) and stack them neatly at designated locations. Their efficient working capacity can significantly improve the cargo turnover and storage efficiency in the yard.
Advantage: The four-link structure makes the crane more flexible in moving and operating in the yard, and it can adapt to different yard layouts and operational needs.
Shipbuilding and ship repair yards
Special application: Four-link gantry cranes also play an important role in shipbuilding and ship repair yards. They are used for heavy duty tasks such as handling large hull components and installing equipment. The stability and safety provided by the four-link construction is key to accomplishing these tasks.
Other industrial fields
Diversified applications: In addition to the above fields, four-link gantry cranes can also find applications in other industrial fields such as metallurgy, mining and construction sites. In these fields, they are used to complete a variety of heavy materials handling and loading and unloading tasks.
It is economical and flexible material handling machines on rails. They are based on the well proven mobile harbour crane technology and can be easily integrated into existing or planned terminal infrastructures. It is suitable for long shoreline wharves, such as shipyards, outfitting wharves and 10,000t berth bulk and miscellaneous compensation wharves etc. It’s widely used in ports, docks, storage yards and other places to complete the loading, unloading and reloading operations of ships and vehicles, building material shops, construction works , energy & mining.

1. The rope stabilizing device of grapple has good stabilizing effect, which significantly inhibits the swinging of spreader;
2.The hinge point of the boom moves upward, which makes the wire rope winding smoothly, prolongs the service life of the wire rope, and is easy for maintenance;
3.Container spreader automatic slewing following technology improves operation efficiency and safety;
4.Electricity feedback technology saves energy and protects the environment;
5. windy alarm, safety dynamic scanning and other safety measures are complete.
