Single Girder Overhead Crane and Double Girder Overhead Crane are a great tool for lifting heavy loads, but they can be expensive. An overhead crane has two major parts: the chassis and the crane head. The chassis is the frame that houses all of the moving mechanisms of the crane, while the crane head is the part that holds the load being lifted. Overhead cranes come in single-girder and double-girder varieties, with each type having its own advantages and drawbacks.
What Are Single Girder Crane And Double Girder Overhead Crane?
A single girder overhead crane is a type of overhead traveling crane that supports the load from one single beam. It can travel in two directions, either along the length or across it.
A double girder overhead crane is similar to a single girder in its mobility and support, but is designed with two parallel beams instead of one. It has less capability for carrying loads than a single girder because it has less surface area available for attachment points on each beam.
Difference Between Single Girder Crane and a Double Girder Crane
The main structural and performance differences between these two crane types are important for selecting the right solution for your facility:
- Single girder overhead crane: Typically used in smaller worksites and being suitable for use in hard to reach areas. Because of the lower number of beams and material required, it's much easier to fit into small spaces and can be assembled more quickly than a double girder crane.
- Double girder overhead crane: Usually larger than single girder cranes because they require two beams and more means to support their load capacity. They have much larger capacities, making them ideal for handling larger loads at once or moving heavy materials across large distances.
Functions of a Single Girder Crane and a Double Girder Crane
Single Girder Overhead Crane:
It is a single beam overhead crane which has one girder. These cranes are designed for lifting and moving heavy loads. Because of its lightweight design, it can be easily installed in a small space. It consists of jibs, beams, hoist motors and control systems. Steel cables or chains run through sheaves at either end of the boom for lifting/moving loads.
Double Girder Overhead Crane:
A double girder crane can lift objects that weigh up to 500 tons. The crane has two girders, which help it lift heavy loads. In order to perform its functions, a double girder crane must be able to move freely in any direction on its base. It must have a hoist system with a minimum capacity of 50 tons, as well as hydraulic jacks and brakes for stability during loading operations.
Cost of Single Girder Crane vs Cost of Double Girder Crane
Single girder crane prices are more affordable:
Single girder cranes are suitable for low capacity lifting. They are ideal for small to medium sized businesses because they can lift a maximum weight of 5 tons and below. Brady & Morris Engineering Co. Ltd is a best single girder eot crane manufacturer in India.
Double girder crane prices are suitable for high capacity lifting:
They are ideal for large businesses that want to lift heavy loads, such as ships or tankers, as they can lift up to 50 tons of overhead material. Brady & Morris Engineering Co. Ltd is one of the leading girder crane manufacturers in India, supplying high-quality cranes to the mining, construction and steel industries for over 60 years.
Conclusion
As we can see above, there are many similarities and differences between single girder overhead cranes and double girder overhead cranes. The main difference is that double girder cranes can lift heavier loads than single girder cranes, but they also cost more to purchase and maintain. If you have a large load to move, then you might want to consider purchasing a double girder overhead crane. Otherwise, if you only need light lifting tasks performed by an overhead crane on a regular basis, a single girder overhead crane would be a better choice.
