Description of Overhead Travelling Crane

One of the most common misconceptions about single girder cranes is that they are not as durable or of the same high quality as double girder cranes. If properly designed, a single girder crane can be the perfect solution for a business that needs a light to medium duty crane, or for a facility where headroom and/or floor space is limited.

Single girder bridge cranes are often the most cost-effective lifting solution for various applications and industries. Single girder cranes use less material and are more compact and lightweight than a double girder crane, which results in a significant cost-savings in material, freight, and installation. Also, because they only require one bridge beam, these systems typically have less deadweight, meaning they can utilize lighter runway systems and tie into the existing building support structure.

Part of the application analysis for a crane system is to determine when to use a single girder crane vs. a double girder crane. In most cases, a single girder crane is less expensive than a double girder crane; however, the cost is not the only deciding factor as both have their merits and shortcomings for particular applications.

The basic construction of an industrial overhead bridge crane consists of, and trucks with wheels running along the length of the runway system and the bridge crane girder fixed mounted to the end trucks with the hoist trolley suspending the hoist and traversing across the bridge.

Technical parameter of Overhead Travelling Crane

Advantages of a Single Girder Design:

Less expensive due to a simpler trolley design, reduced freight costs, simplified and faster installation, and less material for the bridge and runway beams
Most economical option for light to medium-duty cranes
Lower loads on the building structure or foundations due to a reduced deadweight. In many cases, it can be supported by existing roof structure without the use of additional support columns.
Better hook approach for both trolley travel and bridge travel
Easier to install, service, and maintain
Ideal for workshops, warehouses, material yards, and manufacturing and production facilities
Lighter load on runway rails or beams means less wear on the beams and end truck wheels over time
Great for facilities with low headroom
