QD Type Double Girder Overhead Crane 
Brief Introduction:
The QD type Double girder Overhead Crane is a kinds of heavy duty overhead crane to lift and transfer materials and goods.
The Double Girder Overhead Crane are widely used for Hydro Power Station, Power Plant, Steel Mills, Paper Mill, Storage and kinds Factory Workshop. 

The Double Girder Overhead Crane consists of Main Girder, End Carriage, Lifting Trolley and Electrical Parts. Generally, the power supply System for trolley and crane are festoon system and Bus Bar system.
Basic parameter:
1. Capacity: 5t-500t
2. Span: 7.5m-45m 
3. Working Class: A3-A8 (FEM 1am-5m)
4. Speed: 17.7-97.2 m/min 
5. Control Method: Pendent, Remote and Cabin Control
5. Power Source and Painting Color as your demands
6. According to your specific usage, specific model and design will be offered.
1.Heavy Duty and High Efficient
2.Suitable for any environment ( High Temperature, Explosion Proof and so on)
3.Long Life Span: 30-50years. 
4.Easy for Installation and maintenance.
5.Reliable structure
Further more, according to different usage, industry and demands, the QD type Double Girder Overhead  Crane have following improved model:
1. QZ Grab Double Girder Overhead Crane
2. QC Magnetic Double Girder Overhead Crane
3. QDY and YZ Foundry and Casting Overhead Crane
4. QB Explosion proof Overhead Crane

6. QL Suspended Beam Double Girder Overhead Crane
7. QN and QS Multipurpose Double Girder Overhead Crane (Hook, Magnet and Grab)
Electric Parts:
Electric Parts are consists by Cabin, Control Box, Control Panel and Power Supply System. The electric parts we use Chinese top brand: Chint, and the Siemens, Schneider, ABB and Yaskawa are optional brand

The speed are controlled by resistor and Inverter to realize single speed or multispeed. The Inverter control (VVVF) are suitable for precise operation, such as: Hydro Station rotor maintenance.

There are Cabin, Remote and Pendent Handle control methods for the QD type Double Girder Overhead Crane, or any two kinds control methods.

Generally, the Trolley use festoon system for power supply, the crane use Bus Bar system for power supply. And the power source could customize according to your demands.
