Skid Resistance and Friction Tester

Pendulum skid resistance and friction coefficient tester for road surface test ApplicationThe apparatus is used to measure antiskid performance of high grade roads and airport pavement both in lab and in-situ. It is convenient in operation, and with precise testing results, stable performance.Structure1. Foundation: composed by T type legs, levelling screws, and bubbles.2. Upright column: composed by one column, one lifting unit, one guiding rod and one handle.3. Releasing switch: fixed on the cantilever, used to remain level of pendulum rod and release pendulum.4. Steering system: including one tightening handle, one pendulum shaft, one knuckle and one bearing, the whole system connects the pendulum, secures its position and ensure free oscillation in the plane.5. Scaling system: Including needle felt gasket, clamping cap, needle adjusting screw and dial gauge. BPN is read directly from what the needle points.6.Pendulum: composed of upper and lower connectors, oscillation rod, spring, lever, lifting handle, hammer shell, slipping chunk and rubber chunk(76x25.4x6.35mm).
