Product Information
QD electric double-girder bridge crane with hook is the widely used hoisting machinery currently. It is mainly comprised of box-shape bridge, crane crab, trolley travelling mechanism and electric control system. The load handling device is the hook.
On the girder laid rails for crane crab to transversely move. The girder is weld with the box- shaped end girder. At the middle of the end girder are joints which are fastened with bolts for fragmented transportation of bridges. The platform is used to place trolley travelling mechanism, electric equipment and used for repair.
It has three operation modes: ground handle, wireless remote control and cab. There are two kinds of cab: open cab and closed cab, where there are adjustable seat, acoustic alarm and interphone which can be furnished as required by users.
The crane can be furnished with load handling devices such as motor grab, electromagnetic chuck to meet the requirements of hoisting varied types of materials.
The crane, of a classification group of A3-A7, has a commonly used lifting load of 3-250t, so that it is suitable to work in factories, warehouses and freight yards where the ambient temperature is -10 degree—40 degree and the relative humidity is not more than 85%. It is prohibited to wok in the environment with inflammable, explosive and corrosive gas.

Advantages of QD Double Girder Bridge Crane
1. Use optimized computer design box type girder as main support girder.
2. Motor protection class is IP54, F class insulation and equipped with overload protection equipment. (Optional)
3. Specially designed gearbox for crane, adopts oblique gears, self-lubrication.
4. Control stick could be connected with trolley, freely move on main girder separately and can also control the travelling speed according to the different depth of buttons.
5. Longer utility life-span and higher working efficiency.
6. Travelling speed adopts no polar speed adjustment control which result in stable travelling and small sway of crane.

4. Hardness test is available.
5. Customized crane wheels meet differrent requirements.
Single girder VS Double girder overhead bridge crane
1. Girder Stength: A common misconception is that double girder bridge cranes are more durable. Based on the CMAA (Crane Manufacturers Association of America) specifications, both single and double girder cranes are equally rigid, strong, and durable. This is because single girder cranes use much stronger cross girders than double girder cranes, and single girder cranes have lateral bracing.
2. Hook Height: The principle difference between single and double girder cranes is hook height (how far above the floor your hoist will lift). Double girder cranes provide better hook height.
3. Cost Considerations: Single girder cranes may cost less for several reasons:
a. Only one cross girder is required
b. The trolley is simpler
c. Fright expenses are reduced
d. Installation is faster
e. Runway beams are lighter
