Run Down Fixtures for Torque Testers

Run-down-fixtures or Joint Simulators are required for accurate torque measurement of power torque controlled tools (electric, hydraulic or pneumatic). They simulate real-world application conditions, allowing the power tool motor to ramp-up to freely rotate several times before building resistance to rotation. The resistance will increase until the torque that the tool's clutch is set at is achieved and the tool stalls or shuts off.
