The overrun brake simulator operates the brake mechanism on the coupling of a caravan or trailer. A 4m rail to lock the simulator is standard supplied. The simulator locks itself into the rail through air pressure. The rail needs to be concreted into the floor.
The mechanism in the brake simulator, which is activated by air pressure, causes force through the coupling device on the overrun brake. A sensor measures this force. The force is presented on the console of the roller brake tester.
The overrun brake simulator can be used in combination with the RT9001 or RT9002 roller brake tester with an integrated weighing system.
