Learn about the different types of Overhead Cranes available in the Indian market today. There are four different categories of cranes we will discuss here.
The EOT in EOT Cranes stands for “Electric Overhead Travelling”. These types of overhead cranes are stationary and allow for lateral movement across two planes. Not only do they move backwards and forwards but can also move up and down with the load. These cranes are perfect for indoor work. Factories, assembly lines, big warehouses, mining corporations, etc. can make good use of EOT cranes. Low maintenance and ease to operate makes these cranes a good investment, especially if you have trained operators and experience frequent need for heavy load lifting. The only thing to keep in mind is that they are not to be used in explosive and corrosive environments.
Here, the HOT in HOT Cranes stands for Hoist One Track. HOTs are a stationary overhead crane and allow for lateral movement across two planes as well. They are less common as compared to EOT crane as they do not allow for as much movement as the EOT cranes. They are more commonly used for maintenance purposes. They have a hoist attached to the bridge which can be operated using an electric pendant. They are low maintenance and a sound investment if you frequently need a lot of maintenance and repair in your enterprise.
Single-Girder & Double-Girder Cranes
These are variants of the cranes mentioned above. They are both used for heavy-lifting with the double-girder cranes specifically built for maximum load capacity. Due to their need to lift excessively heavy loads, the EOT crane design principles applied are a bit more complex compared to simple EOT cranes. The EOT crane parts such as the hoist and the trolley are more intricate in their design and function as they have to withstand heavier use. Single-girder cranes usually have a load capacity of not more than 15 tons and can span up to 65 feet. While double-girder cranes have no limits in either aspect. So, if your need is of lifting a light to medium weight load then a single-girder crane is the better option.
Lastly, Gantry cranes are specialized types of cranes which come with a self-support structure attached. These cranes have two vertical structural components that bear most of the weight of the crane as well as the load. Used for their sturdiness and ability to withstand wear and tear, these are highly efficient cranes more apt for outdoor use as there is a limitation of supporting structures when working outside. They also usually have wheels attached to the legs, making them mobile. A useful feature, indeed!
