Automotive Free Roller
The free roller is a supporting device used for brake performance testing or speedometer calibration of vehicles equipped with dual rear-axle drive systems. During the test, while the test axle rests on the rollers of either the brake tester or the speedometer tester, the non-test axle should be placed on the free roller, allowing the wheels to rotate freely. This setup ensures that the vehicle remains in a state where it can be driven for testing purposes. When used in conjunction with a brake tester, the free roller significantly expands the operational capabilities of both the brake and speedometer testing equipment. The free roller itself is driven by the rotation of the vehicle’s wheels, accurately simulating real-world driving conditions on the road. As such, it serves as a specialized tool that works seamlessly with speedometers, brake testers, dynamometers, and other automotive inspection devices, enabling comprehensive safety assessments of multi-axle vehicles. This equipment is an essential component of modern automotive safety and integrated performance testing lines.

Automotive Dynamometer (Small Roller)
The automotive dynamometer (also known as a chassis dynamometer) is a core piece of equipment specifically designed to measure a vehicle’s output power and fine-tune its performance—making it especially essential in motorsports and the automotive performance tuning industry. In countries with well-developed aftermarket industries, such as the United States, Australia, and the United Kingdom, dynamometers are incredibly common in tuning shops. To meet the demands of advanced modifications, modern dynamometers are now typically equipped with robust auxiliary tuning features, including power data recording, constant-speed testing, and real-time display of power and torque outputs.
