This series of impact testing machines are used to test the impact resistance of metal materials under dynamic loads. This series of models is also the most commonly used impact testing machine on the market.
 
Technical Features:
1. The main body of the testing machine is a single-support column structure, cantilever-type hanging pendulum, and the pendulum hammer body is U-shaped;
2. The impact knife is installed and fixed by screws, which is simple and convenient to replace;
3. Sample simply supported beam support;
4. The host is equipped with a safety protection pin and a safety protection net;
5. The testing machine is semi-automatically controlled, and the swing, hanging, impact, and swing are all electrically controlled, and can use the remaining energy after breaking the sample to automatically swing to prepare for the next test, especially suitable for continuous impact Test laboratories and metallurgical and machinery manufacturing departments that do a large number of impact tests;
6. The testing machine conforms to the national standard GB/T3803-2002 "Inspection of Pendulum Impact Testing Machine", and performs impact tests on metal materials according to the national standard GB/T229-2007 "Metal Charpy Notch Impact Test Method".
