Four Link Jib Type Container Gantry Crane Mobile Harbour Crane

This jib portal crane has been widely used in port, yard, station, stack and so on. In order to quicken the turnover of the vehicle,
the operation of loading and unloading, transshipment of goods on the shipping and car needs high efficiency. With the advantage of advanced capability, high working efficiency, compact frame, calm movement, comfortable operation, safety and reliability,convenience maintenance, nice appearance and so on, it can make good use of the limited space of the port, yard and other places.

- Electric control equilibrium 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 software. When luffing, the horizontal move of load in ensured, the transmission angle is increased and the pressure angle reduced, by which, the service lift of four bar linkage mechanism is increased.
- The luffing mobile counterweight is adopt so that when operating, the upsetting caused by load is minimized and the service life of revolving support increased.
