Cartesykj Weight dummy Calibration bracket for roller brake tester
Product Overview
The Weight Dummy Calibration Bracket is a specialized support device designed for use with standard weight dummies during the calibration of roller brake testers. It ensures the precise and stable placement of weight loads on the test rollers to simulate actual axle loads, allowing for accurate calibration of braking force measurement systems. This bracket is essential for applying consistent and repeatable loads without damaging the equipment or compromising safety.
Key Features:
Compatible with various types of weight dummies (e.g., 100 kg, 200 kg blocks)
Durable steel structure with anti-slip surface treatment
Easy alignment with roller centers
Adjustable or fixed-position design for different roller sizes or testing lanes
Equipped with safety locks, handles, or guiding slots for secure and efficient operation
How to Use
1. Preparation
Power off the roller brake tester and ensure the rollers are clean and dry.
Confirm that the roller tester is in calibration mode or maintenance mode.
2. Position the Bracket
Place the calibration bracket over or alongside the rollers according to the test system design.
Ensure that the bracket sits firmly and does not shift during weight application.
3. Load the Weight Dummy
Carefully place the designated weight dummy (e.g., 500kg equivalent in modular blocks) onto the bracket.
Align the dummy over the center of the roller contact zone to simulate axle load.
4. Start Calibration Test
Activate the roller tester’s calibration program.
The system will detect the simulated axle load and brake force response.
Record the braking force output and compare it to expected values based on the known load.
5. Analyze and Adjust
If deviations are observed beyond the allowed tolerance (e.g., ±3% force deviation), recalibrate the force sensors or software scaling parameters accordingly.
Repeat the test to confirm consistency.
Why Calibration Is Necessary
1. Ensure Brake Testing Accuracy
Roller brake testers evaluate the braking force of each axle. Calibration using standard weights ensures that the sensors correctly measure braking force relative to axle load, preventing false pass/fail results.
2. Meet Legal and Regulatory Requirements
Many national vehicle inspection standards (e.g., GB21861 in China, EU 2014/45) require periodic verification of braking force measurement accuracy. Using calibrated weight dummies and brackets ensures compliance.
3. Validate Sensor Linearity and Performance
Calibrating with known loads helps detect any drift, non-linearity, or mechanical bias in the brake tester sensors or software, ensuring long-term measurement stability.
4. Build Test Confidence and Traceability
A properly documented calibration using certified weights and brackets provides traceable evidence of the system’s performance. This is especially important for inspection stations, government audits, and quality assurance records.
