The RT5204AB truck roller brake tester is a dual roller bed and can therefore be installed on the left and right side of an inspection pit.

In addition to measure the brake forces per wheel and the difference between the left and right side of an axle, the operator can determine the important quantities rolling resistance, actuation force, ovality (out-of-roundness) and brake fading for each wheel.

Special attention has been given to prevent damage to the tires. The rollers quickly stop when slippage occurs, even during the start-up of the motors.

The RT5204AB is standard equipped with both rollers raised and with a power box with a double soft start. Soft starters gradually increase the power to the brake tester motors during start-up. This reduces the mechanical stress on the motor and other mechanical components and therefore extends the lifespan of the system. This makes this unit suitable for testing in the applied parking brake test mode up to 30 kN.

Also standard are the electronic motor brake and automatic slip detection. The chassis is hot dip zinc and all moving components are equipped with quality bearings. This reduces the maintenance on the brake tester to a minimum.

The brake efficiencies (decelerations) of the vehicle are calculated automatically after manual vehicle weight input or by means of the (optional) weighing facility. These efficiencies can be compared with the legal requirements for the service-, parking- and emergency brake systems.
