First: Check the deflection of the wheels (Side slipe tester).
This unit consists of a gauge plate and a relaxation plate and ensures quick control of wheel alignment to determine if a more accurate check is needed.
This test drive identifies lateral wheel slip, which means lateral movement compared to an ideal straight track.
The width of the relaxation plate is to release any lateral forces already acting on the wheels thus ensuring the reliability of the results.


Second: Suspension tester
The SIRT202 Vibrational Suspension Tester is designed to determine the degree of vehicle suspension efficiency by measuring the grip using the EUSAMA method.
This is based on analyzing the pattern of force that is transmitted from the frame to the test panel during the vibration test, giving a value of 100 for the static weight and measuring the percentage of force change during the vibration cycle with the suspension acting as a damper.
The grip reading indicates the suspension’s ability to keep the wheels in contact with the road surface in the most severe conditions.
These units are suitable for testing the following:
• Weight of individual wheels and axle.
• Percentage of holding single wheels.
• The difference in the grip ratio on the wheels of one axle.
The system’s resonant frequency (corresponding to the state of the minimum force transmitted to the ground)
Third: Inspect the brake system and the brake system (the roller brake tester).
These units are suitable for testing the following:
• Rolling resistance on one wheel.
• Brakes on a free wheel and the percentage difference.
• Maximum braking force on one wheel, on the overall axle.
• The maximum percentage of defects in the brake force.
• The percentage of efficiency of the braking system.
• Handbrake efficiency ratio.
• Split braking capacity between the front and rear axles.
