The Many Uses of a Double Girder Overhead Crane

When choosing an overhead crane, the first thing to consider is definitely the load. You will have to determine a maximum girder load, which should be greater than the body weight of the load. A crane girder is put through vertical and horizontal loads, which can be dynamic and generate vibration. The vertical load is resisted with the entire beam and the lateral load is resisted through the compression flange. A double-girder overhead crane can do carrying a disproportionately large load.

A crane girder was designed to have a load, with all the lateral load placed at the aim of minimum hook approach. To calculate the utmost reaction of the crane girder, the body weight of each and every wheel is multiplied by 25 %.

High quality

A double girder overhead crane is the start of a series of exceptionally heavy-duty cranes. The components of these cranes are primarily comprised of a gantry frame, hoist trolley, and girders or beams that run parallel to the ground. These cranes are generally employed for general material handling and lifting work, and might be made to incorporate special lifting devices. They may be custom-designed to meet specific needs, and offer work class A6 and work classes.

A large-duty crane usually comes with a double-girder structure that can lift around 450 tons. Their sturdy structure, high durability, and ideal safety make them a fantastic choice for warehouses, heavy workshops, and also other heavy-duty applications. These cranes offer convenient bridge-mounted service platforms, which allow technicians to access all parts from the hoist and crane. Just one-girder crane, however, does not permit a bridge-mounted service platform. The 10 ton overhead crane, 15t bridge crane, 50 ton overhead crane all can be double girder machine.

Special applications

When a double girder overhead crane can be used to lift heavy loads, it really is more complex when compared to a single girder model. The constituents are heavier and also have more support columns to help the crane stay level. These cranes are standard in ports and steel production facilities, but they are also commonly used in other industrial settings. The benefits of double girder overhead cranes get them to highly valuable in the development industry.

These cranes have two hooks, the key hook is used to lift heavy objects, even though the auxiliary hook is used for lighter objects. The auxiliary hook will help the main hook in tipping the workpiece or turning it over, if necessary. Both hooks should never lift the same object, along with the weight from the object cannot exceed the ability of the main hook. The double girder overhead crane is accessible with an under running hook for maximum headroom and side approach capabilities.

Higher duty class

A double girder overhead crane has three different classes of service, each of that is explained by its capacity. The light-duty class, also known as an easy-service crane, can be used for light warehousing or repairs. This particular crane has a capacity of two to five lifts hourly. In contrast, a huge-duty class crane is commonly used for industrial facilities for example power houses, transformer stations, and machine shops, the location where the equipment is constantly at 50 percent of its capacity. The heaviest-duty class can be used in cement mills, scrap yards, as well as other industries which need a crane using a capacity of 20 or even more lifts an hour.

A double girder overhead crane has a higher capacity than an underhung crane and is capable of doing moving objects and loads up to 20 tons. It features radio and pendant controls to guarantee safe operation. Double girder overhead cranes are designed for heavy objects, and they are typically utilized in manufacturing plants. The working class of your double girder crane is usually A4 or A7. These people have a range of capacities from five to 550 tons, and are able to accommodate various working conditions.


Should you need a large span or high capacity overhead crane, you may be considering a double girder design. This particular overhead crane is produced with two beams, one at every end, which gives strength and stability. The most expensive type of double girder is the rigid welded steel box girder, which requires significant increases in material and labor charges. Furthermore, double girders require special fabrication and tend to be more costly. This type of crane is suited for heavy industrial applications like aerospace, mining, and steel fabrication. It may also be employed in clean room applications including nuclear reactors.

The normal price of a double girder overhead crane is $29,000 or higher. These cranes are commonly found in warehouses, storage facilities, workshops, and power stations. Some types of double girder overhead cranes use a duty cycle rating of 600 tons, while some are equipped for specific tasks. The price of a double girder overhead crane depends on the specifications of your project. You need to know that double girder cranes have longer spans than single girder cranes, and might move loads over greater distances. Many top bridge cranes producers
