SC25 SC-25 Excavator Hammer Hydraulic Breaker Piston Rock Breaking Piston Demolition Breaker Piston

The main components of our hydraulic hammer
1. Through bolts-42Crmo: Long service life of bolts through the use of this new material
2. Back Head-20CrMo: It is experimented by our desiger many times to make the internal organization tighter and increasing the hydraulic breaker wear-resistance.
3. Front Head-20CrMo: Our material is used by the best quality standard in breaker market,it can serve the breaker to work with longer using life.
4. Control Valve: We adopt production process by grinding machine to improve the size presicion, position accuracy & coordination accuracy.
5. Cylinder Body- 20CrMo: Our material is used by the best quality standard in breaker market,its hardness can reach 61.8HRC; it is more resistant to deformation, ripping and scratching than other domestic breaker.
6. Piston-20Cr2Ni4: Our piston quality is controlled strictly by desiger; it has good hardness of 61.8HRC; it is more resistant to deformation, ripping and scratching than other domestic breaker; it can also reduce scratch problem with grinding process.
7. Chisel-42Crmo: The specially heat-treated chisel is directly applied to break rocks. There are four types for choosing: moil, blunt,flat, conical point.
8. Main Body: Front head, cylinder and back head composed the main body,each part is in best performance.
9. Seal Kit: We adopt both Parker and NOK seal kit which are most famous brand in the business line.

Hydraulic Breaker Chisel
The chisel is a special accessory installed on the hydraulic breaker. It uses the impact energy generated by the breaker piston to transfer the impact energy to the object to be broken by striking the chisel, causing it to crack and break.
Feature: 1. Super wear-resistant
2. low failure rate
3. long life
Hydraulic Breaker Rod Pin
The function of the rod pin is to control the displacement of chisel and enhance the durability of the chisel.
Our rod pins are made of high-quality steel, which is more durable and wear-resistant.

Hydraulic Breaker Piston
The piston is the impact mechanism of the breaker and also the most important component of the breaker.
Feature:
1. Strong wear resistance
2. Good corrosion resistance
3. High tensile strength
4. Good heat resistance
5. Good maintenance performance

Hydraulic Breaker Through Bolt
Bolts are subject to high load, high impact and high wear during the operation of the breaker, so they must be made of high-quality alloy steel with high strength and toughness to meet the use requirements.

Hydraulic Breaker Bush
The Bush are in direct contact with the front cylinder and the chisel, reducing the wear of the drill rod and the front cylinder;
They have a direct guiding effect on the chisel.

Silenced/Box type hydraulic breaker
● Low noise level,suitable for quietness place and cities work.
● Full-closed bracket protects the main-body.
Side type hydraulic breaker
● Shorten the total length,it is more flexible on mining site.
● More convenience to handle the breaking object.
● Easily Maintenance.
Top/Open type hydraulic breaker
● Easy-control and easy-position make it more convenience to excavator work.
● Without side-weight,reducing the rate of chisel breakage.
● Longer total-length and heavier total weight,suitable for building destroy.

Hydraulic Breaker Application Field
☞ Mining:Mining,secondary breaking.
☞ Metallurgy:Clearing slag,demolition of furance and foundation.
☞ Road:Repairing,breaking,foundation work.
☞ Raliway:Tunneling demolition of bridge.
☞ Construction:Demolition of building and reinforced concrete.
☞ Ship reparing:Clearing alam and rust from the hull.
☞ Others:Breaking frozen mud.
