A double girder overhead crane is a lifting solution that can handle medium to high weights. Double girder cranes provide superior support for the products being handled by utilizing two adjacently positioned beams, allowing for the transfer of a bigger capacity. Hoist crane manufacturers in India usually design double girder cranes for loads of approximately over 10 tons. 

The Double Girder Overhead Crane is a two-girder bridge crane with a hook that can handle and transport fixed cross intercropping indoors or outdoors. Lifting capacities range from 5 to 1000 tonnes, with operating levels categorized as A3, A5, and A6. A3 overhead cranes are used to transport maintenance equipment to power plants and other infrequently used locations. A5 is a double-girder overhead crane that is often employed at the working level in factories, mines, workshops, warehouses, and other locations. A6 is a heavy-duty system that is commonly used in high-traffic areas.

Operations of double girder cranes

The double girder bridge mechanism, traveling mechanism, trolley with the frame, and electrical parts were all included in the Double Girder Overhead Crane. Because the frame of a double girder overhead crane is stronger and more secure than that of a single girder overhead crane, the lifting capability of a double girder overhead crane is greater.

Ground operations, remote operations, and driver’s cabin operating modes can all be used depending on the situation. Because of the broad span, enormous lifting capacity, and high lifting height, the driver’s cabin is frequently used. Each crane operating speed mechanism may be configured as a fixed speed; it can also be constructed as a VVVF inverter and used with hook anti-sway as manufactured by the EOT crane manufacturer

How does a good double girder crane work

Renowned manufacturers employ innovative design systems and thoroughly examine all mechanical, structural, and electrical components utilised in the manufacturing of each double girder overhead crane, resulting in cost-effective, dependable, and safe lifting solutions. These companies can create double girder cranes for any industry or use. They may construct customised arrangements, including open barrel hoist designs, to cater to any demand, even in the most difficult of working situations, such as radioactive or underground.

Advantages of double girder overhead cranes

Because of its various advantages, a double girder crane is utilised in a variety of sectors and recommended by every EOT crane manufacturer in Ahmedabad. The following is a list of some of them.

  • Greater hook height is one of the major advantages of double girder overhead cranes. The ability of the hoist to raise the hook above the floor (usually 18-36″ higher than single girder) The biggest span or capacity has no limits, making it perfect for heavy equipment manufacturing and transportation.
  • It’s perfect for hauling heavy loads on a regular basis.
  • Additional features like walkways and maintenance platforms, cabs, magnetic reels, and lights can all be supported by a twin girder design.
  • Double girder cranes are used in a variety of indoor and outdoor applications, including mining, iron and steel, train yards, and ports.

Disadvantages or limitations of double girder overhead cranes

While double girder overhead cranes have many advantages, it has some limitations as well which are below

  • Double girder cranes are more costly due to the additional material costs. Double girder cranes feature more complicated components than single girder cranes, making them more expensive. Double girder cranes are also more costly due to the additional structural support they give.
  • When compared to single girder cranes, double girder cranes have higher freight and installation expenses, making them more expensive. As a result, not all industries can afford them.
  • Hook approach is reduced on double girder top running cranes for both trolley and bridge travel.
