12 Ton Single Girder Gantry Crane 30m Span for Heavy Industrial Lifting

Single Girder Gantry Cranes are used for material handling  (loading, unloading or grabbing materials) processes in small production units and operated on floor mounted rails. The head room of single girder gantry  cranes is normal or low and these can be fitted in different floor areas. Single girder gantry cranes are fitted with crane duty motors and are suitable & compatible for frequent starting, reversing and braking.

 Our single girder gantry cranes designed by qualified engineers and manufactured by qualified boilermakers, electricians and fitters. What’s more, we can design  according to your requirement, also can supply you the technology to weld the  girder in your country. Single girder gantry cranes consist of main girder, a  two legged A-frame support, possible cantilevers, bottom end beams, electric hoist and electric control. The cranes are modular design and have the advantages of easy installation and maintenance with reliable operation, fuse less circuitry, ducted wiring and compact terminals. Ramhoist can design and  fabricate all types and sizes of gantry cranes as we know the rated load, crane’s span and lifting height, like full gantry cranes, semi-gantry cranes  and portable gantry cranes, including, single girder, double girder, single leg, double leg, and cantilever styles for indoor or outdoor service.

 Single Girder Gantry Cranes are self propelled cranes running on rails and traveling  along the rails installed at ground level or set into the floor, they are  rail-operated or track travelling small and medium-sized lifting equipment, the utility model is an ideal choice for indoor and outdoor lifting  operations. They also can be used together with other lifting appliance for special purpose. 

 Referred to as portal cranes, gantry cranes are so named because they are constructed on top of a gantry – a structure designed to support a bridge. Different from  overhead cranes, which don’t have supporting legs, sing girder gantry cranes are outfitted with supporting legs and don’t need support from the building structure or other steel supporting columns. The gantry cranes used for workshop material handling can be portable, mobile, or stationary, which means there are workshop portable  gantry crane and fixed gantry crane. As portable gantry cranes, they can be produced with steel or aluminum or with  both of them, and they can move freely within the working area during the operations to lift and move materials.

 According to different situations, single girder gantry cranes have three types: MH  single girder gantry crane, truss type single girder gantry crane, L single  girder gantry crane. The differences of these three types are explained in the back in details.

 Single girder gantry cranes with the runway located on the floor can be used where the  overhead crane or bridge is not practical or isn’t installed; overhead runways structure are unavailable, columns cannot be accommodated in open areas, existing factory structure cannot bear the wheel loads of the overhead crane; or loads needs to be handled outside the crane span and when the relocation of  the crane is required after the work at a certain site is completed.

 Single girder gantry cranes are widely used to indoors and outdoors with application such as open ground, warehouse, workshop, steel plants, engineering industry, cable industry, granite industry, cement pipe industry, cement plants, highway, ports, container depots, pulp & paper, bulk storage areas, open yard, shipyards, precast yards, rail yards, mining maintenance, hydroelectric power station, bridge construction, infrastructure. It is also a ideal choice for use in a rented factory or in multiple work place.
 Single girder gantry cranes also called single girder door cranes, goliath cranes, single beam gantry cranes,  single girder electric gantry cranes, single girder electric hoist gantry cranes, single girder electric hoist gantry cranes, single beam electric hoist gantry cranes, long traveling single girder gantry cranes, rail mounted single girder gantry cranes, single girder mechanical gantry cranes, portal cranes, electric hoist hanging type gantry cranes, Single girder semi gantry crane, Single girder travelling gantry crane, overhead gantry crane, small gantry crane, adjustable gantry crane, mobile gantry crane, rubber tyred gantry crane, rail mounted gantry crane, harbor freight gantry crane.
