Port or harbour portal crane is used for loading and discharging cargos from ships or shipbuilding. It is suitable at various of ports and shipyards with the help of hook, hanger, grab, container spreader etc. 

► Electric control eauilibrum system is applied to avoid overload of switching and lift mechanism,as a result of which,the outage rate can be reduced.

► The four bar linkage mechanism is optimized by dynamics siftware.When luffing ,the horizontal move of load is ensured,the transmission angle is increased and pressure angle reduced,by which,the service lift of four linkage mechanism is increased.

► The luffing mobile counterweight is adopted so that when operation,the upsetting moment caused by load is minimized and the service life if revolving support is increased.
