Advantages, Pros and Benefits of Double Girder EOT Cranes

1. Advantages, Pros and Benefits of Double Girder EOT Cranes Electric overhead travelling crane or EOT as they are called are the most commonly used overhead or bridge type of crane. From warehouse to workshops, from constructions to ship buildings, rail yards everywhere this type of cranes finds its use. As the name suggests itself this types are operated by electricity. According to the number of girders present EOT can be of two types namely, single girder and double girder. Structural specifications of double girder type The basic function of EOT remains same irrespective of its types. However according to the number of girders the shape and functionality differs to a certain extent. A Double Girder EOT Crane has two girder beams made up of either rolled steel or are incorporated into steel boxes. These two girders actually make up for the bridge of the crane which is in the end supported by two trucks on its two sides. The bridge of the crane is the main strength giver for the setup while the additional steel boxes fabricated provides additional strength to the machine. The trolley and hoist that are present can be top running or under running. If the crane has stop running trolley and hoist that gives provision for maximum room of the hook. If the hoist is placed between or on top of the cross girders then there is an extra expansion in the depth of hook of about 18-36’’. Additional auxiliary structures like inverter drive, radio controls, protection roofs, anti-collision switches etc. can also be added to the main setup as per requirements.

2. Benefits and pros The main benefit of a Double Girder EOT Crane is its efficiency. Running on electricity and overhead bridge nature attributes to its utmost efficiency, proving up to 2-3% more efficient. These types of cranes are best for lifting heavy loads. These overheads can lift comes with abilities like 0.5ton to 100 ton lifting capacity, 3m to 30m span of wings, and 0.5 to 35m lift. Their maximum work capacity and longevity is almost infinite. These overhead cranes can be used not only in outdoors but indoors as well. Although bit cost expensive these EOT double girders find their extensive uses in construction, mining, rail yards, shipping, docks yards etc. Their designs are complex due to their heavy functionality and therefore while choosing manufacturers for EOT cranes it is best to go for the best sellers. A manufacturer having tie ups to big conglomerates, giving guarantee of performance longevity and quality of materials used with experience over decade are the ones to opt for.
