Single vs Double Girder Gantry Cranes

Cranes stumbled on make work easier for industries and warehouses, and choosing to acquire a crane to produce operations smoother is a simple decision. What might not be easy is choosing between the options. That said, there are 2 popular cranes for lifting heavy weights and transporting bulky materials: The one girder and double girder gantry cranes. What’s the visible difference between the two? This is a comprehensive comparison of the single vs the double girder gantry cranes:

Design

This aspect is rather obvious, mainly because it depends on the names of these two forms of equipment. In design and construction, the single girder features one bridge beam and 2 end trucks on each side. The hoist trolley traverses from a single end towards the other on the lower side of your bridge girder. On the other hand, the double girder has two bridge beams as well as two end trucks on each end.

Moreover, the hoist trolley travels on rails which are usually attached to the the surface of the bridge(atravesar grandes áreas). This will make the later hold bulkier materials, developing a more complicated structural framework, as the former is lightweight and suitable for small to medium weight projects.

Cost

Undoubtedly, the main difference in construction automatically alludes into a difference in price. As a result, a double girder crane is much more expensive than a single girder crane. This does not necessarily mean that each and every industry ought to go for that more costly one, for increased performance. Both machines have their own merits and demerits and thus, are right for different industrial applications.

Duty Classification

Though most believe that the double girder is some heavy-duty equipment as well as the single one light-duty, the converse is valid. The structural aspects of the device, are what classify the machine as heavy or light duty. In spite of this, a single and double girder gantry crane(diferencia entre estas grúas) could possibly be the exact same duty, despite having different structural components. And also this reaches durability and longevity. You are unable to imagine that one lasts longer than one other since they vary in fabrication.

The main difference rather depends on the application form. Typically, the double girder crane is utilized for D+ (Very High Quality) or E (Severe Duty) applications. This is due to its heavy-duty motor, open winch having a separate split gearcase, and may be configured to future a bridge-mounted platform for increased stability in handling bulky goods. However, the one girder crane cannot stably support this type of platform, hence handles lighter-duty materials.

Headroom Limitations

Since the hoist trolley travels on top of the double girder crane, it requires more clear height over its elevation. Inside the single girder crane, the hoist hook height is improved by a wide margin. This will make the one girder design quite practical in most runways because they have insufficient clearance space.

End Up

Due to difference in fabrication, therefore cost and headroom limitation, both machines are suitable for different applications. The single girder is preferable employed for light and medium-duty applications whilst the double girder is great for heavier duty class and special applications such as double hoisting systems and die flipping. One that suits you best depends on your industrial specifications!
