Overhead Crane Runway Geometry & Alignment: Wheels, Rails and Travel Behaviour

Review bridge geometry and runway alignment together when wheel-flange wear, skewing, rail contact or travel problems appear.

How geometry problems show up

Recurring wheel-flange wear, crane skewing, irregular rail contact, noise and travel-current differences can point to an alignment issue. Findings are recorded for both travel directions.

• Wheel-flange marks
• Rail contact surface
• Bridge skewing
• Travel-motor current

What data defines the survey?

Runway gauge, level, straightness, diagonal dimensions, wheel axes and bridge squareness are compared with the project tolerances. Knowing the existing geometry before wheel replacement or modernization helps avoid repeat wear.

• Runway gauge
• Level and straightness
• Diagonal dimensions
• Wheel and bridge squareness
