STATIONARY WHEEL INSPECTION
The Dapco Stationary Wheel Inspection System was adapted from the wayside wheel inspection technology deployed at TTCI and at the Union Pacific Railroad.

The Stationary Wheel Inspection system is an off-line application for inspecting rail wheels/wheel sets for possible sub-surface cracks.  The system is typically located in a maintenance/wheel shop facility.  We offer the system in multiple configurations to meet the client’s needs.  We also have the ability to directly integrate the ultrasonic inspection system into wheel truing/profiling machine operations, saving time and reducing operating costs. 

Integrating the Dapco Ultrasonic Wheel Inspection system into the profiling operation allows the end user to inspect the wheel either before or after the profiling operation. Having this added feature provides the rolling stock engineering groups with the flexibilty needed to find the type of defects that cause broken wheel derailments. We have recently installed multiple systems for Amtrak and have formed a Strategic Partnership with Simmons Machine Tool Corporation for use with the Simmons Stanray and Hegenscheidt U2000-400 underfloor wheel profiling machines.
