Crane Names Explained in This Article
Bridge Crane is another name of overhead crane.
EOT Crane is the abbreviation of electric overhead travelling crane.
Double Girder means two main girders / beams, equal with double beam.
Overhead Travelling Crane equal with overhead crane.
Double Girder Bridge Crane Overview
What is double girder bridge crane? As you know, bridge crane also named overhead crane, just different names in different countries. In crane industry, we usually name cranes after its structure, such as, single girder overhead crane and double girder bridge crane, single beam gantry crane and double beam gantry crane. So, that’s easy to understand the name, double girder bridge crane is double girder overhead crane which has two main girders / beams.
Composition of double girder bridge crane
Double Girder Bridge Crane consists of two main beams, two end carriages, lifting mechanism (electric hoist, electric crab hoist, electric open winch), motors, reducers, electrical box, power feeding system, hook (also can be grab, spreader, lifting tongs, electromagnet etc.) and lots of safety devices (buffers, limiters).
Two main beams mean more strong than single beam crane, so, double girder eot crane is one of the most popular overhead crane types in all industries. Faster speed, higher crane working class make them can create more value for your job.
Why is There a Double Girder EOT Crane?
Before double girder eot crane was created, single beam eot crane was the main role in the lifting tasks. However, with the development of the times, the things that need to be lifted are getting heavier and heavier. For lifting heavy materials that over 20 tons, single girder eot crane is very dangerous, as its beam cannot bear so heavy capacities. “How about two beams? Maybe double beam eot crane can lift over 40 tons.” Crane engineers had the idea.
Another factor that prompted the birth of the double girder bridge crane was efficiency. With the rapid development of society, people's demand for products has increased significantly, forcing the industry to continuously innovate production tools. Single girder crane is light lifting tools, only has A3 or A4 working duty. Compare with single girder eot crane, the working duty of double beam eot crane can up to A6, A7 and A8. A higher working duty means that more items can be lifted within the same time period, which greatly improves production efficiency.
Advantages of Double Girder Overhead Crane
- Double main beams design, more strong
- Large lifting capacity
- Higher working duty
- Higher lifting and travelling speed
- Higher lifting height
- Light weight, light wheel load, reliable performance
Features of Double Girder Overhead Crane

Types of Double Girder Overhead Travelling Crane
Normally, double girder overhead cranes are designed as top tunning type, for some special working conditions, they will be designed as underhung type. Top running double beam overhead crane is the overhead crane travelling on the top of crane rails. Underhung double girder bridge crane has the opposite design, the crane is hanged under the crane rails which are fixed on the ceiling, so you also can all them ceiling mounted double girder bridge crane. Yuantai Crane will design suitable double beam overhead crane according customer’s working condition and space.
