Runway Survey is a rail analysis that can potentially increase the lifespan of an overhead crane and its structure. The analysis provides precise information and recommendations for corrective alignment.
In addition to the benefits of increasing the lifespan of the crane, SANS also requires that the crane gantry be within certain tolerances, deviations from these tolerances, leads to increased risk.
Incorrect tracking leads to premature wheel and rail wear resulting in costly repairs and downtime. There is also the possibility that the crane can run inefficiently.
The below are possible reasons why a crane does not travel correctly on a gantry.
- Improper installation
- Corrosion
- Pads are worn
- Rail misalignment
- Rail may be worn
- Structure is bent or uneven due to overloading or geological movement
The analysis is performed by a runway survey.
Morris’s Runway Survey uses a remotely operated Total Station providing a visual inspection on the alignment and condition on your crane rail.
Measurements are 3 dimensional and the following can be analysed from the data collected; span, elevation, straightness and rail to rail elevation. All this data is collected in a single pass of each rail and does not require that multiple measurements are done, resulting in a faster, more accurate survey.
The survey can be conducted on most runways including Overhead Cranes, Port cranes and Portal cranes.
The survey entails:
- Inspection of the crane runway
- Alignment measurements
- Identification of span and straightness
- 2D and 3D visualizations of the rails
- Calculations are focused around measured data and software minimising human error
