The TB-170S type digital display pantograph dropping device special impact tester is developed and produced in accordance with the national standard GB/T3808 "Inspection of Pendulum Impact Tester", and is in accordance with the national standard TBT 1842.2 electric locomotive pantograph skateboard immersion metal carbon skateboard (1 ) Conduct impact test on the metal-impregnated carbon skateboard material. The operation adopts dual control of hand control box and full touch LCD screen, which is easy to operate and has high working efficiency. The remaining energy after the pendulum is used to break the sample can automatically raise the pendulum.
