What Is An Electric Overhead Traveling Crane Anyway?

EOT Cranes | Electric Overhead Traveling Crane | Overhead Shop Crane Functions

The abbreviation EOT stands for electric overhead traveling crane. Even though it has the word electric in its name, it can be operated manually as well. It is for the purpose of moving around specified amounts of weight within a limited area. These are used for handling the weight as well. They are very common in many workplaces which require the moving of load. These areas may either be large factories, research facility centers, and production plants as well. It has a major requirement in industries where it is common that there is a heavy material which needs to be lifted.

Electric Overhead Traveling Crane | Details

Talking about its structure, we can understand how it can lift heavy loads. It has a traveling bridge involved in spanning of the gap, which is connected to parallel runways. The traveling bridge also has a hoist which basically travels on the bridge. The electric overhead traveling crane has a three-step working mechanism. In the first step, the hoist is driven by the motor, which generates power. This power is sent over to the reducer in its high-speed shaft area, which after processing it, sends it to the reducer to reduce the power to the required amount, and then the output is received from the low-speed shaft of reducer. This is how the objects are lifted.

In the second step, the trolley’s crane is driven with power by the motor. The power is again sent to the reducer’s high-speed shaft, from where it goes to the reducer again after being processed. The reducer reduces the power to required amount and output is received through the low-speed shaft of the reducer. Then, through the half gear joint with the trolley. This is how the materials and objects are driven on the crane in the lateral position.

Lastly, the trolleys’ crane is driven again by the motor. Just like as in the second step, power is sent to the reducer; from there it is processed by half gear coupling and sent back to the reducer. The reducer again lowers the power of the motor to the required level and the output is received by the low-speed shaft of the reducer. Here’s the difference between the second and the third step. In the third step, after the output is received by the reducer’s low-speed shaft, it is then received by the full gear coupling joint. In this way, the wheels of the crane move and transportation of the materials is achieved.

Double Girder Overhead Traveling Crane

These cranes have two different models. The single girder electric overhead traveling cranes and the double girder overhead traveling cranes! Whenever there isn’t a heavy load to be lifted, the single girder electric overhead traveling crane is used. Whereas for the process of lifting heavy objects and materials, the double girder is perfect! The reason is that a single girder EOT doesn’t have enough power and space to carry a lot of material and any material that is heavy since it only has a single girder. It has its applications in lightweight lifting work. Although it does have the ability to lift less than a hundred kilogram of load and a maximum load of a few tones. The double girder Electric Overhead Traveling crane can definitely lift a lot more and a lot heavier materials. They have the double girder which helps spread the weight of the load evenly on the machine allowing it to lift more weight.
