Introducción del producto
The Harbour Portal Crane is a fully rotary boom crane installed on a gantry base walking along a ground track.
It is widely used in the mechanized loading and unloading of cargo in ports and docks, the assembly of hulls and the maintenance of ships in the shipbuilding process in shipyards, and the construction of dam projects on the construction sites of large hydropower stations. Its application range is very wide, and it is of great significance to reduce heavy manual labor, improve workers’ operating conditions, and increase labor productivity. It is an indispensable and important equipment for the mechanization of industrial processes.
It is mainly composed of a lifting mechanism, luffing mechanism, rotary mechanism, cart walking mechanism, electrical equipment, door frame, etc.
The Harbour Portal Crane has high work efficiency and can complete hoisting operations on multiple places and various types of goods.
Four link portal harbour crane
Four link portal harbour crane, lever-operated counterweight balance, cylindrical body (or four-legged) gantry form, using hooks or grabs for grocery or bulk cargo loading and unloading operations, container spreaders can also be used for container loading and unloading gantry cranes.
Ventaja
- Beautiful appearance, safe and reliable work.
- Advanced performance and easy maintenance.
- Durable and other advantages.
- It can be widely used in loading and unloading operations of major port terminals, and it is an ideal model for multi-cargo terminals in integrated ports.
- This model can adopt AC frequency conversion speed regulation, PLC control, and can install an intelligent “status monitoring and control system”.
- Adopt an electronically controlled balance system to ensure that the opening and closing mechanism and the lifting mechanism are not overloaded during operation to reduce the downtime rate.
- Use dynamics software to optimize the four-link mechanism to ensure the horizontal movement of the load during the luffing process, while increasing the transmission angle, reducing the pressure angle, and improving the service life of the four-link mechanism.
- The application of luffing mobile counterweight to minimize the overturning torque caused by the load during hoisting operations and improve the service life of the slewing bearing.
