1. Through Bolt
Four through bolts or, tie rods, tie together the front head, back head, and the cylinder.
2. Back Head
The back head contains the cushion chamber or top buffer where nitrogen gas is stored.
The valve controls piston reciprocation.
The cylinder is the heart of the hydraulic breaker, containing hydraulic circuit for piston reciprocation.
The accumulator prevents pulsation.
Kinetic energy of the piston is converted into hammering energy after hitting the tool. The hammering energy transmitted to the tool breaks rocks.
7. Front Head
The front head supports the whole breaker. Upper bushing prevents shock from the tool.
Special treatment makes the tool hard enough to withstand direct impact when striking rocks.
