Top Running Overhead Cranes: Opportunities & Considerations
Opportunity: Top-running cranes are the ideal solution for industrial buildings with limited headroom. Running on rails mounted atop the runway beam, top-running cranes gain extra lifting height over what is possible with an underhung crane. A double girder top-running crane provides greater hook height than a single girder, as the hoist is positioned between the double girders.
Top-running cranes typically are larger with greater lifting capacities, at 20 tons or more. They’re also easier to install and service. For wheel maintenance, they do not have to be suspended, as do underhung cranes.
Considerations: Top-running systems require more frequent rail alignment inspections and more frequent rail alignment than underhung cranes.
