Hydraulic breaker is a powerful percussion hammer fitted to an excavator for demolishing concrete structures or rocks. Such as:

· The primary  and secondary crushing work of a rock mountain

· Crushing cement and asphalts on pavements and removing rocks

· Dismantling building and used in other crushing working sites

· Good quality raw material

· The precision of them is less than 0.05mm 

· The precision of seal groove is 0.03mm , to increase the piston's life 

· Our cylinder(More than 20T), subzero treatment after heat treatment . It is will be lower deformation and less scratch

· We have Vertical grinding machine ( used for more than 30T) to ensure the precision of piston , straightness accuracy. To improve performance and stability

               Warranty:1 year

1. Special material:durable and longer service life.(20CrNiMoA)

2. For larger model, we use special technology, avoid crack. It will be as good as new after six months if you opearte correctly.

3.Vacuum heat treatment, we control the temperature and time of annealing furance by computer and workers. To ensure  durable performance and  perfect quality.

4.After heat treatment, we use subzero treatment in order to reduce the deformation and not easy  scratched ( below zero 130℃).

5.The piston's precision is 0.005mm and concentricity is 0.005-0.006mm. It ensures beating force.

6.The distance between cylinder and piston: 

20T 0.05-0.06mm     30-40T 0.06-0.065       40T 0.065-0.07mm
