Main Features

1, Through bolt
-The longest service life due to applied heat treatment.
-High strength material, prevent parts sudden fracture, and uses the loose prevention design.
2, Nitrogen gas
Reduce the recoil force, and increase impact power.
3, Main valve
Internal control valve system is more efficient by 10% to 15% than other breaker's valve, stay cooler and harder-hitting.
4, Piston
-Maximizes impact energy.
-Minimizes recoil.
-Special heat-treted and harden piston.
5, Chisel
Optimized by high grade steel and special heat treatment so as to offer maximum performance.
6, Back head
The energy of piston stroke is accumulated due to charged nitrogen gas.
7, Cylinder
Uses the high strength steel, special heat treatment process, top and bottom adopted high-performance seal rings, to ensure the best run of piston reducing friction.

Process Equipment

Forge

Material is very important to hydraulic breaker, all material 
was forged, increase material density and strength.

Heat Treatment

This equipment withdraws the air of the cylinder , and fill carbon to cylinder, increase cylinder toughness.

Grinding Machine

The cylinders were ground from head to the end, which can keep concentricity, ensure hammer's striking power.

CNC

We adopt advanced process equipemnt to increase our efficiency to deliver products on time.

Mounting Bracket

Advantage: Thicken Material 
All HMB hydraulic breaker come with mount and pins, easy to connect with H-bracket and excavator arm . 
Separate design : easy disassembly, also could use for loader.

Main Body

Name: Cylinder /accumulator 
Advantage: The density of main body is much stronger and it's hard to deformation.

Big size hydraulic breaker designed with accumulator, accumulator reduce the irregular pulse pressure in the hydraulic circuit pipe, so increase the strick power the make more powerful hydraulic breaker.

Low noisy

Name: Box Silence Type Bracket
Advantage:Whole body inside , and the buffer & guide 
plate effectively reduce the vibration noise .
More suitable for the city work situation .

Welding technology

Name: Welding 
Advantage:Our welders have many years welding experience, the surface of the welding points is quite smooth and solid .

Packing & Delivery

Standard spare parts: two Chisel, two hoses, one spare seal kits, one Nitrogen bottle, one charging kit, one tool box and the User's Manual. 

Inner is stretch film

Outside is export wooden case or as customer's request.
