Description
Double girder gantry crane is composed of bridge frame, long traveling mechanism, trolley, winch and electrical equipment, etc.The bridge adopts box-type double-beam welding structure, and the operation mechanism of the trolley is driven separately, and all the mechanisms are operated in the driver’s cab.
Double Girder Gantry Crane Main Component
- Main Girder
- Flexible Leg
- Ground Beam
- Rigid Leg
- Lifting Trolley
- Heavy Duty Trolley Festoon System
- High-strength Alloy Forged Hook
- LT Wheel Mechanism
- LT Power Supply Cable Reel Drum
- Maintenance Platform
This setup enables efficient and secure heavy load lifting and movement, making the double girder gantry crane a reliable solution for various industrial applications.
Double girder gantry crane is suitable for open warehouse, yard, railway freight station, port dock cargo area, such as loading and unloading and lifting.Can also be matched with a variety of spreaders for some special work.
Design
- Double Girder Gantry Crane Systems are designed in accordance with ISO, FEM and DIN standard.
- In double girder gantry crane, mechanism selections are made in accordance with the desired lifting and running speeds and working class.
- The use of box-shaped double beam welding structure, increase the working space and easy to transport, installation and maintenance.
- The car adopts the opposite rail cable conductive device.
- Standardization, serialization and generalization of parts and components.
- There are two kinds of cable coil type (divided into left and right end) and sliding line type (divided into left and right end) for users to choose.
- The driver’s cab has a wide field of vision and a linkage console, which makes the operation flexible, balanced and comfortable.It can also be equipped with fan, hot air device, air cooler, air conditioner, walkie-talkie, etc.
Advantages
- Steel structure: Q235B/Q345B carbon structural steel with seamless once forming technology more strong and elegant. Suitable for different operation temperature;
- Lifting mechanism: Reducer, drum, motors protection class F class, China or World top quality motor brands, such as Jiamusi, SEW, ABM, etc;
- Hook: Finest steel forged hook, long using life;
- Wheels: Vacuum casting, with compact structure, convenient maintenance, high transmission efficiency and long service life;
- Travel mechanism: With China or world famous crane motor, reducer supplier, such as ABB, SEW etc;
- Electrics: ABB, Schneider or Siemens etc.
