Free fall drop test machine /drop hammer impact test machine
Free fall drop test machine /drop hammer impact test machine
Application:
The drop hammer impact test machine is mainly used for non-ferritic steels ductility transition temperature of the sample drop weight method, the test method is a certain quality of the hammer raised to a certain height, then there is static released, hammer body free fall impact to the sample surface, thereby determining the impact resistance of the sample. The drop hammer impact test machine integrating mechanical, electrical, automatic control technology, and to achieve a lifting hammer, feeding, shock, grab the hammer fully automated process. In addition to the testing machine is equipped with multi-channel protection measures, greatly improving the safety of operating personnel and equipment use. This machine is applicable for nil ductility transition temperature testing of ferrite steel.
