Basic disposition:
1.Imported sealed parts used in the hammer rod and piston;
2.Automatic lubricating system;
3.On-line digital display detector of oil temperature and pressure (Germany);
4.Electronic control system of SIEMENS;
5.Man- machine conversation screen of SIEMENS;
6.Bypass circular cooling and filter system;
7.Main oil pumps: angle-type plunger pumps;
8.42 malfunction check points (hydraulic, electronic) with 36 automatic check points;
9.Welding hammer framework;
10.The counterblow hammer��s tups which have the equal weight strike each other with equal striking stroke by the hydraulic driving;

Performance and features:
A.High integrated power units adopts PLC fully hydraulic driving to realize no pipes connecting to ensure no leakage, high efficiency and energy saving;
B.Multinomial safety measure, circumspect on-line detecting and simplified system design can ensure safety and reliability;
C.Normal PLC energy control ways can be adjusted and set optionally and easily;
D.90% hydraulic parts are standard and easily purchased with simple construct and lower run cost
