If your crane is experiencing excessive wear on wheels and rails, has broken wheel flanges, or you’re frequently replacing bridge couplings and axles – you may need to take a deeper look at rail alignment.
The RailQ Runway Survey has been designed to deliver accurate information on the alignment of your crane rail and expert recommendations for any needed corrective actions.
Is your crane traveling correctly on the runway?
Cranes should travel or track along their runway rails with a minimum of skew and without binding. Improper tracking leads to premature wheel and rail wear, resulting in costly repairs and downtime, as well as inefficient and suboptimal crane operation.
There are many reasons why a crane does not travel correctly on the runway:
Rail may be misaligned or worn
Clips may be missing
Pads may be worn
Runway structure is uneven, bent or twisted due to column settlement, overloads or impacts
Improper tracking is normally investigated by performing a traditional runway survey. However, these surveys may result in days of costly downtime, and the results may not be accurate or clear and may not offer corrective actions.
RailQ uses a remotely operated robot to minimize downtime and increase the safety of the survey. It provides information on runway span, straightness, elevation and rail-to-rail elevation.
What’s included in a RailQ Runway Survey?
RailQ can be performed on virtually any runway including those for overhead cranes, port cranes and woodyard cranes. The runway survey includes:
A visual inspection of the crane runway
Measurement of the alignment of your crane runway.
Calculations based on measured data with proprietary analysis and visualization software
3D and 2D visualizations of the runway rails
Identification of straightness, span or elevation issues
Konecranes engineers review all collected data and provide recommendations for corrective actions.
Get a complete view of crane and rail geometry
Konecranes RailQ Runway Survey and CraneQ Crane Geometric Survey work together for a complete view of crane and rail geometry.
Do your cranes suffer from premature wheel wear, rail wear, structural component failures or drive faults? All of these are common results of incorrect crane geometry. Have your crane operators complained about a crane making strange noises or positioning incorrectly? CraneQ™ Crane Geometric Survey can help you find the root cause of these symptoms to avoid major problems and costly downtime.
Designed to provide accurate information on the alignment and square of a crane
With CraneQ, we verify the crane for squareness, meaning the end trucks must be parallel to each other and perpendicular to the bridge girder for the crane to track properly. In addition, the geometry of the end trucks themselves is verified, as is the alignment of the wheels within the end trucks. Finally, the girders for the crane are measured for camber.
Accurate geometric analysis guides corrective actions
CraneQ is based on advanced and traditional measurement methods. Proprietary software and skilled survey technicians provide an extremely accurate geometric analysis of your crane. In addition to the survey results, we share our expertise to help you to plan corrective actions.
