Harbour Portal Crane
Harbour portal cranes are widely used in ports, wharves, yards and other places to complete the loading, unloading and transferring operations of ships and vehicle loads with grabs or hooks. The design, manufacture and inspection are carried out in accordance with DIN, FEM, IEC, AWS, GB and other advanced standards at home and abroad, as well as the latest national standards.
The electrical drive adopts all-digital AC frequency conversion, PLC control speed regulation unique technology, flexible control and high precision.
Port portal cranes are categorized into single boom and four-link types according to the form of jib structure. Single boom portal cranes have simple structure, large lifting capacity and light weight. Four-link portal cranes use a combination of jib systems to realize the luffing process of horizontal movement of goods, with a small horizontal drop, smooth luffing, low power consumption. Both types of gantry cranes can meet the requirements of general cargo, bulk cargo and container loading and unloading operations, with a wide range of applications, high operating efficiency, stable operation of the machine and other characteristics.
