Crane Runway Alignment
FHS provides comprehensive crane runway alignment studies in order to make sure that crane tolerances are within the Crane Manufacturer’s Association of America (CMAA) requirements. We will check elevation levels, span, straightness, and the condition of runways and rails.
A Properly Aligned Crane Is Essential
In order to meet the rigorous performance demands within the material handling industry, we provide professional crane alignment. Poor alignment can cause crane skewing or binding, uneven rail and wheel wear, and can put strain on motor drives and other equipment. It can also cause excess stress to the runway beams and supporting building structure.
Through the use of transit and laser equipment, our certified technicians will evaluate the crane and runway conditions and determine the best method for correcting any discrepancies. If out of elevation, the runway is shimmed so that it’s all level. In the case of under-hung cranes, beams would be adjusted while shimming. This might consist of re-drilling holes in order to move the nuts and bolts over. 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.
