Single or double-girder crane?

A common misconception about overhead cranes is that double-girder cranes are perceived to be more durable and of higher quality than single-girder cranes. “Both types of overhead cranes are, however, equally durable and of the same high quality,” says Leon Strydom, Industrial Crane Products Sales Manager for Konecranes Southern Africa.  “On the contrary, single-girder cranes can actually have plenty of advantages over double-girder cranes,” he adds.

Benefits of a single-girder crane

A single-girder crane is more compact and lighter than a double-girder crane, which makes it a preferred choice for facilities where headroom and floor space is limited. Even in situations where items have to be lifted and moved close to the building walls, a single-girder crane can have a better end approach to the building, allowing the hook to move closer to the wall. With only one girder, minimum deadweight is applied to the building foundations, allowing for more cost-effective building designs and runway constructions. On top of that, less steel is required to manufacture the girder, making it an inexpensive lifting solution for various applications and industries.

Understand various lifting needs

A single-girder crane may not, however, be the most suitable choice in every scenario. If a higher lifting capacity, height of lift or a service platform is needed, a double-girder crane might be the better option. It is always important to understand the requirements of the lifting task and the environment where it is planned that the crane will operate, to provide the best lifting equipment for the site.
