Application

The drop hammer tester is suitable for various pipes (PVC-U water supply pipes, sewage pipes, low pressure water supply pipes, low pressure water pipes, core foam pipes, double-wall corrugated pipes, PE water supply pipes) and the impact resistance of plates Determination is also suitable for rigid plastic plates.

Key Features

1. SIMENS PLC controls and touch screen provide high reliability and versatility.

2. Automatic specimen feeding and automatic posting.

3. Frame structure is made of solid steel plate with high stability under impact.

4. Special design tools for support change.

5. Tup body is made of high strength steel plate with high impact resistance.

6. Use chain to lift striker with high precision in height.

7. Self-lock design for striker clamping.

8. Full-closed safety shield.
