Details of outdoor use double girder gantry crane

The wheels of crane crab, main beam and end carriage are produced in casting workshop. This makes our wheels more elastic, and outer surface hard-wearing and durable.

The trolley are assembled with motor, reducer brake, trolley frame, drum hook, pulley, rain cover and other parts. It includes lifting mechanism and cross traveling mechanism. The trolley is strictly designed according to the application and working environment.

Main beam is painted with zinc rich epoxy primer. It is cut by plasma numerical control cutting machine. The butt weld of tension flange shall undergo ultrasonic or x-ray flaw detection as specified.

Outrigger consists of rigid outrigger and flexible outrigger. All connection points are connected by high-tension bolt. The ladder is used by operator to enter into cab or arriving at winch. When the span is more than 30m, it needs a flexible leg to reduce the lateral thrust of the trolley to the rail when the girder lifts materials.
