Single and Double Girder EOT Cranes Applications - Techmech

Selecting the right Electric Overhead Traveling (EOT) crane ensures operational efficiency, safety, and cost-effectiveness in material handling processes. Single and double-girder EOT cranes are the two main types of EOT cranes, and each is suited for specific applications. Here's a concise guide to help you make the right choice.

LOAD CAPACITY

Single Girder EOT Crane: Best suited for small to medium size loads, normally not more than twenty-five tons. These cranes are well suited to applications such as assembly lines, maintenance work, and in small to medium sized warehouses.

Double Girder EOT Crane: Designed specifically to suit high utilization profiles, double girder cranes can transport loads of up to 25+ tons, with the possibilities of reaching 250+ tons. These cranes are appropriate for steel industries, cement Industries, power plants, ship builders and industries dealing with heavy machineries.

SPAN AND LIFTING HEIGHT

Single Girder: Suitable for shorter spans which go up to 40 metres and limited lifting going up to 30 metres. The hoist is mounted beneath the girder, slightly reducing the lifting height.

Double Girder: Designed for wider spans going well over 40 metres and applications requiring greater lifting heights. The crab assembly hoist is fixed across the girders and this enables the enhancement of the vertical lifting capability.

OPERATIONAL ENVIRONMENT

Single Girder: Ideal for light-duty environments, such as workshops, small manufacturing units, and standard warehouses.

Double Girder: Designed for demanding use and unfavorable conditions. They can also include supplementary hoisting gear, corridors, and floors, which makes them appropriate for applications such as with power stations and large-scale warehouses.

COST AND MAINTENANCE

Single Girder: More economical in terms of initial investment, material cost, and maintenance. It is a cost-effective option for lighter and less frequent operations.

Double Girder: While they may initially cost something more compared to other overhead cranes of similar size, double girder cranes will prove to be more durable and efficient for use under these circumstances. They may cost more initially to install than their counterparts because they can carry more load and last longer.

Customization and Features

Single Girder: Option of choice is small for this variant and primarily geared up for basic needs.

Double Girder: Highly customizable, and comes with added functionalities like auxiliary hoists, walks, service platforms, and high adaptability to complex operations.

Long-Term Considerations

However, if you feel that in the future there may be more production demands or loading capabilities needed, you are better off with the double girder crane. Thus, the business model brings the opportunities of scalability and the flexibility of future development.

Safety and Standards

Single and double-girder EOT cranes, though used as different products, must conform to specific safety codes depending on the geographical location or the sector and its particular requirements. Self-constructed cranes such as the double girder cranes are, however, very useful mainly when it comes to more intensive use of the crane since they offer more safety measures.
