MQ5070Ca Portal Crane is single jib support, applicable to lifting operation for ship building enterprise. The main hook can make the displacement track of hook close to horizontal during the luffing process using rope drum compensation method, rotation bearing uses slewing bearing, realizing 360 degrees full circle slewing for crane through the driving mechanism.

This crane is comprised of main & aux hoisting, luffing, slewing and travelling mechanism. Because of using single jib and steel rope luffing, especially for the typhoon frequently area and coastal wharf, in order to resist the typhoon, jib can be put down to wharf surface, and easily to maintain.
