20t 7~30m Hydraulic Portal Crane Port Crane
This type of portal crane is a new type of port loading and unloading equipment,which is self-researched and developed by our company.
It is combined with portal crane and traditional marine deck crane.
So it has the advantages of light weight, low cost, low energy consumption, small wheel pressure, etc.
It can be widely used in small terminal and inland port.
