AJCE was established in February 1990 to serve the needs of the construction, demolition and mining industries. Up to 2000, AJCE had enjoyed a high reputation for good quality supplier of hydraulic hammer breaker parts such as cylinder, piston, valves, etc. to many companies, which also requested us providing main body assembly as OEM.
