Pendulum Skid Resistance and friction Tester/Pendulum Coefficient Testing Machine

Use

It is used to measure the friction coefficient of highway, city road, airport runway and so on

structure

1. Base: it is composed of t-leg, leveling wire and leveling bubble, which can level and support the instrument.

2. Column: composed of column, lifting mechanism, guide rod and instrument handle, it is used for lifting and fixing the position of swing head.

3. Release switch: the switch installed on the cantilever is used to maintain the horizontal position of the pendulum rod and the effect of releasing pendulum falling.

4. Steering system: including fastening handle, pendulum shaft, steering knuckle and bearing, connecting pendulum and fixing position to ensure free swing in the swing plane.

5. Indicator system: including pointer felt ring, pressing cover, pointer adjusting nut and dial, the pointer can directly indicate the pendulum value.

6. Swing head: it is composed of upper and lower joint, swing bar, spring, lever, lifting handle, hammer shell, sliding block and rubber sheet (76mm*25.4mm*6.35mm), which has a specified torque on the swing center and a specified pressure on the road surface.The moment balance between front and back, left and right is the measure of road friction coefficient.

 Main technical parameters

1. Pendulum mass: 1500 ±30g

Center of gravity distance: 410 ± 5mm

2. Positive static pressure of rubber sheet on road surface: 2263g

3. The number of times when the pendulum is freely lowered from 5 degrees of inclination to the swing stop shall be no less than 70.

4. The swing center distance of the outer edge road of rubber sheet is 510mm.

5. The total weight of the instrument is about 12Kg.
