CDKA PLC Hydraulic Counterblow Hammer
The weight ratio of the CDKA PLC Hydraulic Counterblow hammer��s upper to the lower tup is 1:4, which are linked by hydraulic coupling, In the drive of hydraulic power the two hammer tups realized relative motion and are guided by framework with same energy, lower hammer tup��s micro motion and about 6m/s relative velocity
Its framework is assembled by welding steel plate, which won��t support the vertical shock by blow during running. On the top of the framework there is hydraulic power drive system and on the bottom there is elastic damping isolation system. So they will thoroughly avoid the influence of vibration to environment by blow.
CDKA PLC Hydraulic Counterblow Hammer��s hydraulic power drive system adopts the fully hydraulic power drive principle with highly integrated tapered valve control structure to realize high reliable running.
CDKA PLC Hydraulic Counterblow Hammer��s control system realized man-machine conversation, operation status display and common failure display by the touch-screen. It realized the digital control of blow energy and program control of striking.

Performance and feature:
1. High energy-saving
2 .High accuracy
3. No vibration
4. Fewer investment
5. Lower using cost
