How to choose the most suitable hydraulic hammer ?
1.Know the tonnage of excavator
2.According to the needs of specific projects
3.Depends on market demand

Raw Material.

The material we choose is high quality heavy duty wear resistant steel.They are
high hardness and good abrasion resistance after the heat treatment.
Reliability has been improved by revising the shape of the piston and rod impact
surface in order to enlarge and improve the shape of the impact contact area, and
by changing the materials and heat treatment (increased hardness).
Hydraulic sealing systems.

The seal wear resistance, thermal resistance, and sealing capabilities of the
piston seal system have been revised in order to increase durability and life and
give even higher reliability.

Rod pin.

A longer & wider rod pin has been employed that increases the area of the rod pin
subject to pressure, with durability improved by the increased diameter.
