JL Series Drop Weight Tear Testing Machine

This machine is used for drop weight tear test of ferrite stell (especially all kinds of pipeline steel). This machine is composed of frame part, feeding part, lifting part, hammer part, anvil part, safety protection part and control system.It adjusts the impact energy through adjustment of weight thallium quantity and impact height, the energy range is stepless from zero to full speed.

Usage and Characteristics
It is used for drop weight tear test of ferrite stell (especially all kinds of pipeline steel). Different size hammer and anvil can be customized to meet other types of impact test.
