We adopted korean design and advanced technology, SOOSAN hydraulic breaker with higher impact force and low fault rate.

The Characteristic of China Excavator Rock Hammers:

Main Body of China Excavator Rock Hammers:

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 stricpower 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 

Mounting Bracket of China Excavator Rock Hammers:

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

7.The ship hull in mussels , derusting

8.Other: ice breaking, breaking the permafrost and vibrating sand.

Main Features of Excavator Rock Breaker:

Through bolts: Longer service life by to applied heat treatment.


Back head: Material: 20CrMo, impact energy is accumulated due to charged nitrogen gas in the block.


Front Head: Using 20CrMo material, high quality with long life using.


Valve: We adopt production process by grinding machine, with high precision.


Cylinder body: Material: 20CrMo, it is best quality material.


Piston: Longer service life by optimized design and high quality special steel.

Front Head: Using 20CrMo raw material, which are provided by domestic famous manufacturer, forging again and again to make internal organization more tight and increasing the hydraulic breaker wear-resistance.


ChiselThe 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.  


Main Body: Including Front head, cylinder and back head. Ensure your breaker will be in best performance


Seal Kit: We can supply both Parker and NOK seal kit which are most famous brand in the business line.

China Excavator Rock Hammers Working Principle:

    Hydraulic breaker hammer has become an important working tool for excavators, and some people install the hydraulic crushing hammer in the backhole loader  (also known as two busy) or wheel loaders to carry out the crushing operation. Hydraulic breaking hammer, also known as hydraulic breaker or hydraulic Stone breaker.

Hydraulic Breaker without Accumulator:

Simple structure, Low failures rate

Easy maintenance, low cost and impact energy increase. Therefore, users can reduce the cost of using and maintaining two aspects at the same time.

Hydraulic Breaker with Accumulator:

    In the case of single strike, the strength will be slightly larger, no space can be found during the installation and maintenance, otherwise the nitrogen will be leaked, which causes the crusher to strike weak and the accumulator diaphragm damaged.

The Function of Accumulator:

The accumulator is filled with nitrogen, which uses hydraulic hammer to reverse the remaining energy and piston during the previous blow.

The energy stored in the tank is stored at the same time, releasing energy at the same time during the second strike, increasing the hitting ability, usually not hitting the crusher itself.

    The accumulator is installed in the case of energy to increase the striking force of the crusher. So there are no accumulators in small hydraulic hammer, and medium and large ones are equipped with energy storage.

Maintenance for China Excavator Rock Hammers:

Hydraulic Oil

Please choose No.68 hydraulic oil in winter and No.46 hydraulic oil in summer. Oil should be clean & sufficient during working. Dirty oil will cause damages to the Breaker. Please check regularly if Breaker’s cylinder, accumulator, oil pipes & hoses leak oil. If oil leaks, please replace O‐ring & oil seal in time.

Chisel, Chisel Pin & Bushing

Before each working, check if the chisel pins are in good conditions. Check regularly the clearance between bushing and chisel, too much clearance will cause piston & chisel broken. If outer diameter of chisel abrades more than 3mm, or inner diameter of bushing abrades more than 6mm, please replace new ones.
