Pendulum Skid Tester

Model: HM-602W
Price: $4,574.00

The Pendulum Skid Tester quantifies the potential of automotive tire skidding using samples prepared on an Accelerated Polishing Machine.  This model also evaluates the skid resistance of surfaces and polishing tendencies of aggregates. Units measure skid resistance when a rubber slider on a 20in (508mm) pendulum arm contacts a test surface. The drag pointer measures friction on a 0—150 scale. A supplementary 0—10 scale and a special baseplate are provided for work using smaller sliders. Adjustments to the arm position and base maintain a true circular path when operated on sloping road surfaces.

Sliders are made with a graded rubber strip bonded to an aluminum backing plate. Gilson supplies both large and small rubber sliders mounted to aluminum plates or as unmounted replacement pads. 3in (76mm) wide Large Sliders are recommended for testing road surfaces.  1-1/4in (32mm) wide Small Sliders are suggested for testing polishing wheel specimens. Base Plate is 25x19x2in (635x480x50mm), LxWxH, including a specimen mounting block.
