Model: DIT203B, DIT303B, DIT603B
Maximum impact energy: 2000J, 3000J, 6000J
Functions:
This type of machine is specially for conducting drop-weight test to determine nil-ductility transition temperature of ferritic steels
Features:
1. Special design tools for support change
2. SIMENS PLC controls and touch screen provide high reliability and versatility.
3. Automatic specimen feeding and automatic positing
4. Frame structure is made of solid steel plate with high stability under impact
5. Tup body is made of high strength steel plate with high impact resistance
6. Use chain to lift tup with high precision in height
7. Self-lock design for tup clamping
8. Full-closed safety shield
Standards:
GB/T 6803-86, ASTM E208-95a
