Great benefits of double girder overhead crane

Many customers choose double girder crane for their work. Double girder cranes can be either top running or under running in design. A top running double girder bridge crane will provide the most overhead room, as well as the greatest hook height.

Double girder cranes are recommended for heavy-duty applications where the crane has to handle heavier capacities and longer spans. Because of this, the components of the crane system, including the hoist and trolley, are more complex in design—making double girder cranes more expensive than a single girder crane.

They also require more material for the bridge beams and the runway system, so extra consideration should be given to the building’s support structure. Additional tie-backs or support columns may need to be added to handle the additional deadweight on the supports or building foundation.

Double girder bridge cranes are ideal for lifting heavy loads and can be used in more frequent operation than a single girder crane. They can also be used both indoors and outdoors, in a bridge or gantry setup, and are frequently used in mining, iron and steel production, railyards, and shipping ports.

The price details of double girder traveling crane

Except for quality, price is another important factory that influences the purchase. For such heavy duty overhead crane, the price is not low in common. So what are prices of double girder cranes? How to ensure the price and quality of crane?

Crane cost is influenced by many factors, such as the crane manufacturer, the quality, the market, the producing technology, the delivery. And customers’ requirements also influence the crane price. For example, crane with explosion proof hoist is much expensive than common crane.

To get a cost-effective overhead crane, customers should pay more attention to crane suppliers. Reliable and professional crane supplier can provide best products and fist-class service, such as AIMIX Group. Our company wins high praise because of qualified cranes, reasonable price and one-stop service. If you are interested in our cranes, just contact us now!

Consider about crane system design

A crane that requires a high capacity, wide span, or high lifting height will benefit from a double girder design. A single girder design can be an inexpensive option for a light-duty crane in a production, storage, or assembly facility.

Careful consideration should be given to the design of your overhead crane system. A crane that requires a high capacity, wide span, or high lifting height will benefit from a double girder design, but may cost you more money upfront. Lighter duty cranes that don’t have hook height requirements or abnormal capacities or spans can be an inexpensive option that will help improve the efficiency and safety of your production or assembly facility.

Double girder crane and hoist classifications

Class A- infrequent or standby

These cranes are best for precise handling at slow speeds. They are good choices for powerhouses, public utilities. Turbine rooms, motor rooms, and transformer stations.

Class B-light service

This class is ideal for environments with light service requirements and low speed needs. They can handle two to five lifts per hour, and work well for repair shops, light assembly operations, service buildings and light warehousing.

Class C-moderate service

These cranes are built for use in machine shops, paper-mill machine rooms, and other such environments with moderate service requirements. They can handle loads that average 50% of the rated capacity, making five to ten lifts per hour, with not over 50% of the lifts at rated capacity.

Ensure all loose material, parts, blocking and packing have been removed from the load;

Remove any slack from the sling and hoisting ropes before lifting the load;

Make sure that the lifting device seats in the saddle of the hook;

Verify that the load is not heavier than the maximum load capacity.
