The Weight Dummy Calibration Bracket is a precision support device engineered for roller brake tester calibration. It provides stable placement of standard weight dummies on test rollers to simulate actual axle loads, ensuring accurate braking force measurement system calibration. This essential equipment delivers consistent, repeatable loading while protecting equipment integrity and maintaining safety standards.

• Compatible with standard weight dummies (100kg, 200kg, 500kg blocks)
• Durable steel construction with anti-slip surface treatment
• Precise alignment with roller centers for accurate load simulation
• Adjustable or fixed-position design for various roller sizes and testing lanes
• Integrated safety locks, handles, and guiding slots for secure operation

1. Preparation: Power off the roller brake tester and ensure clean, dry rollers. Confirm calibration or maintenance mode activation.
2. Position Bracket: Place calibration bracket over or alongside rollers according to system design. Ensure firm, stable positioning without shifting during weight application.
3. Load Weight Dummy: Carefully place designated weight dummy (500kg equivalent in modular blocks) onto bracket. Align over roller center contact zone to simulate axle load.
4. Start Calibration Test: Activate roller tester calibration program. System detects simulated axle load and brake force response. Record braking force output and compare to expected values.
5. Analyze and Adjust: If deviations exceed tolerance (±3% force deviation), recalibrate force sensors or software scaling parameters. Repeat test for consistency verification.
