JB-300B/500B Semi-automatic Impact Testing Machine Product Description:

This series of impact testing machine is used to test the performance of metal materials to resist impact under dynamic load, so as to judge the quality condition of materials under dynamic load.

Equipment operation is simple and efficient, lifting swing, impact, put swing electric control, and can use the residual energy after the impact test automatically lifting swing ready for the next test, especially suitable for continuous impact test laboratory and a large number of impact test metallurgy, machinery manufacturing and other industries;

The main body of the tester is a single support column structure, cantilever hanging pendulum, pendulum hammer body U type;

Impact knife using screw mounting fixed, simple and convenient replacement;

Specimen simple support beam type support;

The host is equipped with safety protection pins, and is equipped with safety protection net.
