minimum distance between structure beam & overhead crane

How to Measure Span and Runway Length for an Overhead … An overhead crane’s span is essentially its width across the bay—or the measured center-to-center distance between the runway beams. It’s important because it determines how much material is required to build the bridge girders and most significantly affects the cost of the overhead crane .

Crane Structure Service – Crane 1 Services As an example, a runway system can be designed to support a 10-ton crane along with two 5-ton cranes. Depending on the runway design, there may or may not be restrictions to the allowable distance between the loaded cranes.

European Double Girder Overhead Crane – FineWork Cranes European double beam series bridge crane can effectively make use of factory space, and make the headroom lowest and the limit distance between hook and two sides walls minimum. European design concept reduces the weight of the whole crane, and can greatly save the cost of the plant. How to Measure Span and Runway Length for an Overhead … An overhead crane’s span is essentially its width across the bay—or the measured center-to-center distance between the runway beams.

Endtruck: Advantages and Disadvantages of Single Overhead Bridge Cranes 5/6/2018 · Overhead cranes that operate with a minimum of two overhead runways built into a building’s support structure are more commonly referred to as “bridge” cranes. The bridge serves two purposes – first, it’s a load-bearing beam running the entire width of the work area and second, it’s the structure connecting the runways on which the hoist moves.
