Special impact testing machine for pantograph dropping device

The special impact tester for pantograph dropping device is independently developed by Liangong to measure the impact resistance of the pantograph slide plate of electric locomotives and the metal-impregnated carbon slide plate under dynamic load. The impact testing machine adopts dual control of hand control box and full touch LCD screen, which is easy to operate and has higher working efficiency.
Brief introduction
The TB-300 type special impact tester for pantograph dropping device is used to measure the impact resistance of the pantograph slide plate of electric locomotives in the railway industry under dynamic load. It is developed and produced in accordance with the national standard GB/T3808-2002 "Inspection of Pendulum Impact Testing Machine", According to the national standard TBT 1842.2-2002, the impact test of the metal-impregnated carbon slide material is carried out. The testing machine has a large impact energy, and the impact energy is 300J.
