Brief Introduction
Four link type level luffing crane is an common type portal crane, which is widely used in loading and unloading bulk cargo (like coal, ore) in wharf, steel plant and ship yard as well.
Advantages
The four link type level luffing crane has such advantages as reliable operation, high efficiency and so on.
Structure
Four link type level luffing crane is of common type, which is composed by steel structure, lifting mechanism, luffing mechanism, slewing mechanism, crane traveling mechanism, spreader device (as grab / clamshell, container spreader, magnetic, hook and etc.), electric device and other essential safety and accessorial device.
The luffing mechanism can be rigid gear or rigid bar, where the reliable operation can be assured.
Simple structure of steel structure is composed by jib, A-shape frame, slewing platform and gantry.
