55 - 65 Tons Quayside Crane For Ship Loading And Unloading Harbour Portal Crane
Harbour Portal Crane introduction:
The quayside container crane (referred to as the quayside crane) is the main equipment for loading and unloading containers between the container ship and the front of the wharf. Some wharfs also use the large span and large back extension of the quay crane to directly carry out the yard operations. The loading and unloading capacity and speed of the quay crane directly determine the productivity of the terminal operation, so the quay crane is the main equipment for port container handling. Along with the vigorous development of large-scale container ships and technological progress, quay cranes are constantly being updated, and the technology content is getting higher and higher. Low energy consumption and environment-friendly development.
