Description
MQ Four Link Portal Jib Crane is mainly used for loading and unloading of general cargo or bulk cargo in port, jetty, river terminal. It consists of lifting mechanism, luffing mechanism,slewing mechanism,gantry traveling mechanism;Lifting mechanism, luffing mechanism and slewing mechanism could work independently or work together. It can carry load luffing and make horizontal displacement. The crane can rotate 360°free with the combined action of lifting and luffing, and it runs smoothly. This model adopts two types luffing method:Rack and pinion luffing and Wire rope luffing (compensation for multiple pulley blocks).
