| description | Pneumatic ram road surface coefficient of friction measuring device is a stationary device that measures the coefficient of friction of a particular spot on a road surface using a known and precise amount of resistance force supplied from a pneumatic ram and a calibration valve. Pneumatic ram road surface coefficient of friction measuring device comprises a testing tire and wheel mounted to a carriage plate that is slideably attached to a framework that pivots around the front end of the framework and is supported by a jack mechanism at the rear end. Pneumatic ram provides resistance to the sliding action of the carriage plate that may be varied using the calibration valve. Pneumatic ram road surface coefficient of friction measuring device further comprises a sliding gauge indicator and coefficient of friction graduations that provide the coefficient of friction reading. |
