This kind of gantry cranes is a kind of mobile, full-swing, four-bar combination crane, which has balanced jibs and counterweights and is used for lifting containers by hooks or grabs. Located near berths, wharves, piers or terminals where ships dock.
Four-link gantry crane is mainly composed of steel frame, hoisting mechanism, luffing mechanism, slewing mechanism, crane traveling mechanism spreader device (grab, container spreader, hook and grid plate), electrical equipment and other necessary safety equipment.
The steel structure includes jib and A-frame, slewing platform and gantry frame.
Boom : The boom is a long truss structure that extends both horizontally and vertically.
Jib:The jib is usually an additional support arm or sling that extends from the boom to provide additional strength and support for lifting cargo.
Hoist or hooks/grabs:The tip of the boom is connected to the hook or grab, depending on the type of cargo. For bulk loose cargo, like in bulk carriers, a bucket-like grab is mostly used for operating the cargo, whereas a hook is used for containers. These hooks or hoist blocks are often lowered below the boom tip using tough slings or cables.
Gantry or column or legs:Depending on the crane's configuration, a gantry or pillar-like singular column structure supports the boom mounted atop. If the crane is characteristic of two supports in an overhead beam-like configuration, it is a typical gantry configuration where the boom rests on two truss-like legs, known as a gantry structure.
Platform or foundation: For pillar leg or column-like configurations, the entire structure rests on a bottom foundation that essentially transfers all the oncoming loads from the top
Cabin:The crane must be operated and controlled by a designated operator or personnel sitting in an enclosed room with all consoles and systems. The cabin is always situated above, close to the boom.
Rails,wheels,and chassis:Today, most big cranes run on a set of wheels laid on a rail track. However, smaller mobile harbour cranes are also fitted with normal truck tyres and can move in any direction like a conventional vehicle.
Application
Four-link gantry cranes are widely used in harbor loading and unloading, shipyards and metallurgical industry for material handling.
