Through bolt: The front head, the cylinder and the back head of the main body are tightly fixed with four through bolts.
Valve: The cylindrical compensates for pressure in the hydraulic circuit piston reciprocation.
Piston: Kinetic energy of the piston is converted into hammering energy after hitting the chisel. The raw material:20CrNiMoA(best),35CrNiMoA, 40CrNiMoA,and other suppliers use the only GCr15 to decrease the cost.
Main Body: Including Front head, cylinder and back head. Ensure your breaker will be in best performance
Chisel: The specially heat treated chisel is directly applied to break rocks. There are four types for choosing: Moil, Blunt, Flat, Conical Point. The material is 42Crmo.
Ring Bush & Front Cover: Guiding the chisel while they are working. Using 20CrMo steel as raw materials, which are provided by domestic famous manufacturer; forging again and again to make forming, to make internal organization more tight, and increase products’ wear-resistance.
Seal Kit: We can supply both Parker and NOK seal kit which are most famous brand in the bussines line
