Crane Runway Alignment

Material Handling Systems provides an in-depth crane runway alignment service that is in accordance with CMAA requirements.

To meet the rigorous performance demands within the material handling industry, a properly aligned crane is imperative. Poor alignment can cause problems, including: skewing or binding, uneven rail and wheel wear, and strain on motor drives and other equipment. In addition, excessive stress to the runway beams and supporting structures can occur.

Our certified technicians will evaluate the crane and runway conditions, and determine the best method for correcting any discrepancies, through the use of transit and laser equipment.  If out of elevation, the runway is shimmed so that it's all level.  In the case of under-hung cranes, we recommend "floating one runway."  Normal tolerance of beams will cause the wheels to bind as they pass down the runway. Using special sway hangers eliminates this binding. In the case of top running cranes, alignment procedures typically consist of shimming the beams, and adjusting rail hook bolts or rail clips to align the crane rail.  The beams would go up/down to level through the use of shims and the crane rail would be adjusted side-to-side.
