JL-50000 DWTT Drop-weight Tear Test Machine

The drop hammer impact testing machine is mainly used for ferrite steel drop weight tear test (ie DWTT). Also can be customized according to user needs in different forms of hammer and anvil to meet the requirements of other test methods.
Introduction
1.The drop hammer impact testing machine is mainly used for ferrite steel drop weight tear test (ie DWTT). Also can be customized according to user needs in different forms of hammer and anvil to meet the requirements of other test methods.
2.The machine consists of frame part, feeding part, lifting system, hammer, anvil, safety protection system and control system. The machine can adjust the impact energy by adjusting the weight of thallium and adjusting the impact height, and the energy range is stepless adjustable.
