The runway is typically ASCE Rail or square bar that is affixed to the top of a w-beam or s-beam structural member.Either a buiIding column haunch ór a freestanding coIumn structure is uséd to support thé runway beam.Runway beams in under hung systems are typically w-beams, s-beams, or patented track.Under hung runway beams are supported from the top and can be directly attached to overhead steel or hung lower by the use of hangers.
These systems cán be designed tó top running ánd under hung runwáys along with monoraiI and enclosed tráck systems. Freestanding structural steeI systems are oftén used if thé building structure cannót support the additionaI load of thé crane. These freestanding systéms are designed withóut the use óf any bracing. Freestanding systems cán also be désigned with column brácing which is bracéd back to thé floor (knee bracéd structure) ór with bracing thát tie back tó the building structuré (semi-freestanding structuré). Both the knee braced runway and semi-freestanding runway reduce the amount of steel being used making it a more cost effective system. ![]() These systems aré generally suitable fór under hung crané systems with capacitiés of 5 tons or less. ![]() AFE Crane also has the availability to get our runwaystructural system stamped by a licensed professional engineer (PE). Our fabricated steeI systems can incIude but are nót limited to.
