Single and double girder overhead travelling cranes are primarily composed of four main components: the lifting unit, the bridge running unit, steel construction (girder, platform, etc.), and electrical installation. These cranes are typically positioned on the ceilings of closed work areas.
Since these cranes do not occupy space on the ground, they allow for more efficient use of the workspace.
We offer turnkey design, manufacturing, and installation services for all sizes and capacities, taking into account our customer's operational processes, special requests, and the suitability of the installation site.
What is the difference between a single girder and a double girder overhead travelling crane? What are the selection criteria?
• In single girder overhead travelling cranes, the lifting unit is positioned underneath the girder. In double girder overhead travelling cranes, the lifting unit is positioned above the girders. Crane selection is based on the suitability of the distance between the rails on which the bridge running unit will move and the ceiling. The appropriateness of the workspace and the customer's operational process are taken into consideration, and a joint decision is made.
• In cases where high capacity and span are required, and if the customer's operational process is not affected, the use of double girder overhead travelling cranes will generally be more suitable. Otherwise, special design may be done to use a single girder overhead travelling crane.
• The hook coverage area within a factory is much better in single girder overhead travelling cranes compared to double girder ones. If none of the conditions mentioned above create any incompatibility, a single girder overhead travelling crane may be preferred.
