Gantry crane is a variant of bridge crane, also called gantry crane. Its metal structure is like a door-shaped frame, with two supporting feet installed under the main beam, which can walk directly on the track on the ground, and the two ends of the main beam can have outhanging cantilever beams. Mainly used for outdoor cargo yard, stock yard cargo, bulk cargo loading and unloading operations. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and are widely used in port freight yards.
Double girder gantry cranes is suitable for the handling and loading and unloading of international standard containers. The container adopts the form of traction trolley, which makes the whole machine structure light, advanced performance, high production efficiency, good maneuverability and low sensitivity to ground unevenness. The whole machine is powered by a cable reel.
MG Double Beam Gantry Crane with Hook
MG type double beam gantry crane with hook is mainly composed of mast, crane trolley, cart operating mechanism, driver's cab and electrical control system.

The operation method adopts a closed cab, with adjustable seats, insulating mats on the bottom plate, tempered glass windows, fire extinguishers, electric fans, heating and cooling air conditioners, buzzers, walkie-talkies and other auxiliary equipment can be configured according to user requirements.
MG Gantry Crane for Subway Construction
The MG type gantry crane for subway construction is a special gantry crane developed on the basis of the general gantry crane according to the requirements and working conditions of underground construction. It is specially used for turning over soil and lifting objects during underground construction.
The crane is composed of a trolley, a mast, a cart operating mechanism, a hydraulic turning mechanism, a cab and electrical equipment.
The trolley is equipped with a hydraulic turning mechanism, which is composed of a hydraulic work station and a slag turning hook.
There is a hook in the middle of the hanging beam for lifting general objects.
The operating mechanism of the cart adopts 8-wheel 4-drive form. The motor fixed on the trolley drives the wheels through a vertical reducer, and is equipped with a windproof rail clamp. When the crane is working normally, the clamp of the rail clamp leaves the track. When the crane stops working, the operator puts the clamp down , Clamp the track to prevent the crane from sliding.
The direction of soil dumping depends on the construction site.
MG Double Beam Truss Gantry Crane
The MG type double beam truss gantry crane is mainly composed of a gantry, a crane trolley, a cart operating mechanism, a cab and an electrical control system.
The portal frame is a truss structure, which has the advantages of light structure and strong wind resistance. Including main beams, upper beams, outriggers, lower beams, walking trolleys and walking platform railings, etc. The main beam adopts a triangular truss structure with tracks laid on it for the crane trolley to move laterally in the direction of the main beam. The outrigger is a truss structure, which is assembled and welded by section steel. The walking platform is used for placing electrical equipment and for maintenance purposes, and there is a protective railing on the outside.
The operation method adopts a closed cab, with adjustable seats, insulating mats on the bottom plate, tempered glass windows, fire extinguishers, electric fans, heating and cooling air conditioners, buzzers, walkie-talkies and other auxiliary equipment can be configured according to user requirements.
ME Shipbuilding Gantry Crane
ME type shipbuilding gantry crane is a gantry crane with large lifting capacity, large span and large lifting height, which is specially used for large-scale hull section transportation, docking and overturning operations in the dock.
