Description
The A&D Rolling Resistance Test Rig (RRTR) is a high-accuracy drum-based rolling resistance test machine. The RRTR offers world class repeatability and accuracy through its rigiddesign and a customized loadcell developed using our Model-Based Sensor (MBS) technology. Built with consideration for ease of use, maintenance and calibration, it offers automated and manual test scheduling along with a user-friendly operator interface. The RRTR is available in a variety of configurations and sizes for passenger car (PC) and truck and bus (TB) tires, so that customers choose the machine that best fits their needs. Customization is possible depending upon customer needs.
