LGW-50D microcomputer controlled graphite impact testing machine

The LGW-50D microcomputer-controlled graphite impact tester is a testing equipment developed and manufactured by Liangong for a railway supporting enterprise to determine the impact resistance of friction carbon blocks for railways.
 
The graphite material impact test equipment adopts circular grating angle measurement technology, which has the characteristics of high accuracy, good stability and large measurement range. The digital measurement shows the breaking power, impact strength, pre-elevation angle, rise angle, average value of batch test, automatic correction of energy loss, printing and storage of test reports and other functions.
