stone hydraulic breaker hammer for excavator HITACHI
Product Description
Side Type Breakers
Reducing total-length
More convenience to handle the breaking object
Easy maintence
1. Main Valve
1) Easy to repair
2) To prevent the cylinder deformation
2. Piston
1) Piston stroke, increase blow f orce
2) Special damping system, reduce the recoil force
3) Precision of piston and cylinder is further improved, reduce resistance, improve efficiency
3. The high quality of chisel
1). Alloy steel raw material selection.
2) The depth of heat high precision processing
3) Heat resistance, wear resistance strong
4. The whole box shell
1) The durable welding structure, chisel protection more perfect and more stable
2) The seal is complete, eff ective dust control measures to improve the durability of structure, protect against cylinder damage and the bushings premature wear
3) The big plate with light weight, simple structure ,convenient operation and repair
5. Nitrogen chamber
1) Structure more compact
2) Ensure the reduction of the nitrogen chamber volume of the nitrogen pressure under the condition of invariable, the hammer is more energy saving
6. Tool Bush
7. Tool Pin
8. Accumulator Ass'y
1)The accumulator compensates for pressure in the hydraulic circuit and precents pulsation.
2)It's not usually nessary to Refill.
3)Use N2-gas only.
9. Cylinder
10. Back Head
11. Through Bolt
The front head, the cylinder and the back head of the main body are tightly fixed with four through bolts
1) Easy to repair
