20T Double girder gantry crane with European style wire rope Trolley
Gantry cranes are all types of cranes which lift objects by an open winch which is fitted in a winch and move horizontally on railwys. Gantry cranes are an excellent alternative to permanent indoor overhead cranes, which minimal investment in a new building. In addition, they can be disassembled and moved to a new location easily.
Double Girder Gantry Cranes are with heavy loads up to 700t and spans can be over 50 meters. For fabrication and freight-transfer applications, it can move loads rapidly and smoothly.
Double girder gantry crane is ideal for outdoor applications where lifting facilities are provided without the cost ofa building or any supporting steel work. They are also suited to indoor applications where existing building structures are not suitable to take overhead cranes, Hengyuan can be constructed with a cantilever to allow handling outside the rail centers.

8 . Safety feature
Overload protection. Main lifting motor with thermal protection. Hooks with latch. Rubber buffers. Crane switch and travel end switch. Emergency switch can stop all movement when any dangerous happened. Sub-assemblies characteristic are tested before assembly. All cranes must be pre-assembled and tested before leaving factory and offer the certification of test
The double girder gantry crane have many advantacges , like reasonable structure , favorable performance , smooth starting and stopping , safe and reliable traveling . And low noise , commodious cabin and good view , convenient maintenance, excellent . , exchangeability for parts and components , energy saving,reduce energy consumption , using transducer for travelling or traversing crane to realize step speed or stepless speed change , primer and finishing paint , crane structure: steel box type .
Double Girder gantry cranes are used for loading and unloading of outdoor cargo yard, stock yard and bulk cargo. Can walk directly on the track on the ground, and the two ends of the main beam can have overhanging cantilever beams.Metal structure is like a door-shaped frame, with two supporting feet installed under the main beam.
Gantry cranes have high site utilization, large operating range, wide adaptability and strong versatility characteristics. T和double girder gantry cranes are widely used in port freight yards. Applies to the open warehouse or rail along for general handling and lifting work. Also can equipped with many lifting device for special work. Prohibited for lifting high temperature solution, flammable, explosive, corrosion, overloading, dust and other dangerous operations.
