The Challenge
GO Transit's Bridge Inspection Unit underwent extensive stability testing over three months. While the unit performed adequately on level ground and standard rail configurations, it encountered significant operational limitations on steeper super elevations. Since the unit's purpose was strictly for bridge inspection rather than crane operations, Objective Engineering Inc. recognized an opportunity to recalibrate the stability parameters according to ANSI A92.8 standards (Vehicle Mounted Bridge Inspection and Maintenance Devices).
The Solution
Following the modifications, the unit underwent rigorous testing on a 6-degree rail slope, including operation under a bridge—the exact scenario that had previously caused difficulties. The successful completion of these tests led to:
Issuance of a new Stability Report
Recertification with updated National Safety Mark documentation
Comprehensive updates to the operator's manual with new stability charts and information
This demonstrates the importance of equipment-specific engineering in specialized applications. By recognizing that bridge inspection units operate under different parameters than standard cranes, the engineering team was able to implement targeted solutions that enhanced both safety and operational efficiency.
The reconfigured Bridge Inspection Unit now allows GO Transit maintenance crews to safely inspect bridge infrastructure across their entire rail network, regardless of track geometry or elevation challenges.
