Motorized pendulum impact tester JB-500B/JB-W500A

for Charpy testing

Impact Testing Machine JB-500B/JB-W500A is mainly used to determine the anti-impact capability of ferrous metal materials with high toughness, especially for steel and iron and their alloy, under dynamic load. This machine can be operated semi-automatically. The pendulum of the machine can be raised or released automatically. Be applicable for continuing testing in different kinds of laboratories and other metallurgy industrial manufactories. It is designed and developed according to national standard GB/T3808-1995 “Pendulum Impact Testing Machine” and ISO148-2, ASTM, and do impact test for metal material according to the GB/229-1994 “Charpy Impact Test Method for metals”. • Max. striking energy 250J, 500J • Pendulum preparing angle 150º • Distance between pendulum center and impact point 800mm • Impact velocity 5.4m/s • Span of specimen seat 40mm • End face radius of specimen seat 1～1.5mm • Radius of impact knife 2～2.5mm • Angle of impact knife 30º±1º • Thickness of impact knife 16mm • Specifications of specimen 10×10×55mm • Net weight About 550kg • Dimension 800×578×1450mm • Power supply 3 phases 4 lines, 50Hz, 380V • Power of motor 180W
