1 PC New Pendulum Tester Portable Skid Resistance Tester Testing Tool

Description: Portable Skid Resistance Tester 154003 Product Introduction The skid resistance tester is used to determine friction coefficients of road surface, airport runway, marking paint, etc., and to determine the friction coefficients of typical road surfaces to provide a basis for various tire compounds. The tester is characterized by convenient debugging, simple operation, less impact on traffic during measuring, more stable data, and usage in both indoor and outdoor circumstances.

Base support: comprised of T shape leg, leveling screw and level bubble, it’s used for level and support purpose; 2. Column: comprised of column, lifting mechanism, guiding rod, handle, used for lifting and fix the head; 3. Release switch: installed on the pendulum rod, used for keeping the rod horizontal position and to release the pendulum; 4. Steering system: comprised of fixing handle, pendulum shaft, steering knuckle, bearing, it’s used to keep the pendulum can freely swing within the plain; 5. Indicating system: comprised of pointer felt coil, pressing cap, pointer adjusting screw and scale plate, pointer can directly indicate the value; 6. Pendulum head: comprised of upper lower connector, pendulum rod, spring, lever, lifting handle, hammer shell, slider, rubber piece(76mm*25.4mm*6.35mm), it has specific torque to the swing center, also specific pressure to the pavement. 　 Operation Instruction Select points On the test pavement, along with the left wheel running direction, choose 5 representative points, each point apart by 5-10m. Leveling Place the tester on the test point, let the swing direction same with the car running direction; Rotate the leveling screw to let the level bubble in middle position. Zero setting 1)Pointer position calibration: let the pendulum in perpendicular status, dial the pointer to let the upper part closely contact the adjusting screw, now the pointer pointing position should align to the pendulum rod center position, otherwise should adjust the adjusting screw to let the pointer align with the pendulum rod center position, after adjusting should fix the screw thus to fix the pointer adjusting screw position; 2)Release fixing handle, rotate the lifting handle to lift the pendulum and let it be in freely swing status, then screw the fixing handle; 3)Let the pendulum move to right, let the positioning snap ring enter into the on-off slot, let the swing rod locate in horizontal release position, meanwhile, dial the pointer by left hand to let it closely contact the screw on the needle dialer; 4)Press the release switch then pendulum will swing to left, and drive the pointer to move upward, when pendulum move to the highest position then drop, catch the pendulum rod by left hand, now the pointer should be in zero point, if not, can fasten or release the pointer adjusting screw till the pointer is in zero point. Sliding distance calibration 1)Use rubber brush to clean the test area of pavement; 2)Let pendulum freely hang, let the ruler center align to the pendulum rod, let the sliding ruler parallel to the test direction and close to the rubber sheet; 3)Release the fixing handle, rotate the lifting handle to let the pendulum fall slowly and meanwhile let the pendulum to move to right, place slider on ruler right side and let it contact pavement surface and align to the ruler scale, then let the pendulum move to left, and place slide on left side and let it contact pavement surface and align to the ruler scale, then screw the fixing handle and recheck the sliding length, during this process can perform fine adjustment of the sliding length by leveling screw, let the sliding length keep within 126±0.5mm, note that the level bubble should in middle position during regulation. Test procedure Spray some water on pavement, then use rubber brush to brush the road of the mud, then spray water again, and press the release switch to let the pendulum slide on the surface, pointer will then indicate the pendulum value(generally first time not record); when pendulum swing back to right, catch the pendulum rod by left hand, lift the slider by right hand, and let the pendulum move to right, let the positioning snap ring enter into release switch, repeat the operation and test 5 times(every time should spray water) and record each time value, the difference in 5times shall not over 3 units, if not, should check and find out the reason. Test result 1) Each point takes the average value of 5 tests as the friction coefficient; 2)The friction coefficient is calculated by the pendulum value to divided 100, if the pendulum value is 33, then the coefficient is 33/100=0.33. 　 Noted matters 1.Due to the friction coefficient is influenced by whether and temperature, so should record the test date and pavement temperature when testing; 2.Should record the pavement structure type, appearance, period of operation; 3.When pendulum move to left and return, shall catch the rod to avoid to damage the slider and pointer; 4.Within the sliding range shall not have obvious convex and concave shape; 5.When calibrate the Sliding length, should subject to when the rubber is just contact the surface, should not slide forward by the pendulum force, otherwise the calibrated sliding length will have error; 6.To indicate the most harmful condition of the road, should choose the part with lower coefficient and frequent brake, that’s just the left wheel along the running direction. 7.When use new rubber sheet, should firstly test on dry road for 10times then test on wet road for 20times, then can be used. Rubber sheet abrasion long side not surpass 3.2mm, short side not over 1.6mm, otherwise should replace with new one. And if the rubber sheet was polluted should not use again. The rubber sheet effective lift is 12months, shouldn’t use again regardless it was used or not. Because the rubber will aging, the elastic and hardness will change thus will effect the test result. Maintenance & Storage & Transportation 1.It’s kind of precision instrument, users should protect it from any damage otherwise may effect the test accuracy, before operation should read the user manual carefully and get familiar with the instrument structure and operation method. It’s not allowed to uninstall the instrument at will except the flexible or the removeable part. 2.After operation, clean the instrument and stored into the case, place it in the room with good ventilation, no acid, no corrosion. 3.During long distance transportation, the instrument should be kept in case, no sudden impact or over shake during transportation. 4.Should be calibrated at least once every year under normal condition 　 Item Include Portable Skid Resistance Tester 154003 新建网页 2 Shipping & Handling Details Default Shipping Cost or Free Shipping Information: ▲ Default shipping cost or free shipping service is only for the lower 48 United States by UPS Ground or USPS.
