Overhead EOT cranes

Overhead EOT cranes are one of the most common lifting solutions in industry. The Electronic Overhead Travelling crane as its name implies is an electricity operated crane that is designed to move overhead with the support of two steel rails that are parallel to each other. The EOT crane also known as the bridge crane is used extensively in many industries including construction, engineering, loading and offloading industries. The coil transfer cart is often used in place of the overhead crane, however it is important to note that the EOT crane has quite a number of advantages over the coil transfer cart.


The electronic overhead crane has two types which are the single girder and the double girder cranes. Basically, they perforn almost the same tasks however the intensity of the task dertemines which crane is to be used. The single and double girder designs are the major contributors when it comes to the complexity and cost of the crane system. If your company is considering one of these, you would do well to equip yourself with knowledge on the differences of these two and the advantages of one over the other.

Single Girder Overheard EOT Crane


The Single girder overhead electronic crane system consists of one beam that is supported on either side by an end truck. One very popular misapprehension is that a single girder overhead electronic crane is not as hardwearing and its quality is poor as compared to the double girder crane. That however is just a misconception. The strength of the single girder crane lies on its intended function. If it is used for the function for which it is designed it can be the perfect lifting solution, probably the best. One advantage that the single girder crane has over the double girder one is that it can be installed in places where space is limited and still not be an inconvenience. This actually is one other reason why an overheard crane is more preferred even to the coil transfer cart. Apart from being able to fit in tight spaces, single girder cranes are cost effective. They use way less material in comparison to the double girder cranes, are compact and above all they are insubstantial. The one disadvantage that the single girder crane has over both the double girder crane and the coil transfer cart is its limit in terms of capacity and the height of the hook. Hardly would you find a single girder crane that can carry more than 15 tons working at more than 65 feet above the ground. If used within its weight and height limits, the single girder can be the most efficient and economic solution.

Double girder Electronic Overhead Crane


In this type of crane, two parallel running overhead girder beams make up the bridge on which the crane is suspended. Both beams are supported on either side by an end truck. In most cases, the hoist and the trolley are designed to run on a rail that is on top of the girders. Double girder overhead cranes can either be top running or under running. The top running crane system will have quite an advantage over the under running one as it provides more overhead space. The greatest hook height can also be achieved when the crane is top running. When it comes to heavy duty applications, the double girder crane is the most recommended. Due to the double beam system in this type of crane, the weight of the load can be evenly distributed across the crane. In comparison to the coil transfer cart, both of these heavy duty machines can carry extensive loads, however the coil transfer cart still has a disadvantage over the double girder crane because it operates on the ground and hence can be an inconvenience in places where saving space is essential. The best part about using double girder cranes is that they can be used both indoors and outdoors, which makes them effective for many engineering operations, mining as well as construction. The double beam crane has a number of advantages over the single girder cranes. These among others include that:

1.They can ferry heavier loads in comparison with the single girder crane
2.They have a greater hook height than the single girder crane
3.They are suitable for use in more industries than the single girder crane
4.The double girded cranes have more features which are not available in the single girder including the walkway.

Although they are quite the ideal overhead cranes, they still have some disadvantages including the fact that they are more costly and need high maintanance. Between Overhead cranes and coil transfer carts there is definitely a lot to consider. However a choice should always be made after considering space, function and above all the costs involved in purchasing the crane.
