Double Girder Bridge Crane 10 Ton Overhead Bridge Crane
Product Information
When heavy loads and wide spans are required, double girder overhead cranes show their strength.
1. Double girder overhead crane with trolley series use fixed wire rope electric hoist as lifting mechanism (Main hook and Auxiliary hook). fixed on bi-rail trolley, fitted with double girder bridge.
2. This overhead crane is heavy duty class overhead crane, the capacity from 5ton to 50 ton. The span from 10.5m to31.5m, the working grade is A5-A6. working temperature within -25 to +40 centigrade.
3. This overhead crane (bridge crane) is characterized by more reasonable structure and higher strength steel as a whole, the main beam and end carriage are made by U-section steel plate.
4. Widely used in machinery fabrication, metallurgical plant auxiliary workshop, storage, stock ground, and power station.
5. It is also can be used as regular double-girder overhead crane in Textile industry or food industry.
6. It is forbidden to use in inflammable, explosive or erosion environment.
7. It mainly consists of strong bridge girders, trolley-traveling mechanism, crab and electrical appliances, and could be classed into several working grades, for instance: A5,A6, according to the working frequency and time.

Advantages of QD DoubleGirderBridgeCrane
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.
Safety Features of QD DoubleGirderBridge Crane
1. Overload protection device
2. Top quality long time bearing polyurethane materials buffer
3. Crane traveling limit switch
4. Voltage lower protection function
5. Emergency stop system
6. Lifting height limit device
1. Main beam and end beam packed by plastic cloth and plastic film.
To protect the crane from scraped, chipped, the sea erosion the painting.
2. Other small parts wil packed by wooden case, and every small parts will be marked.

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
