Hydraulic Breaker Piikki GA045 (7 - 14) 729kg
Green Attachments’ hydraulic breakers provide a powerful, durable, and reliable solution for all construction, demolition, and earthmoving tasks where brute force is needed to break through rock, concrete, and hard materials.
Our range covers models for mini-excavators all the way up to large crawler machines. Whether you're working on a demolition site, quarry, or major infrastructure project – we have the right tool for the job. Typical applications are excavation assistance, demolition etc.
The impact energy is generated by hydraulic pressure and nitrogen gas pressure together at the top of the piston. There is gas chamber (back head) at the top of the piston and isn’t included accumulator, thus this type of breaker is called “gas type breaker”. Gas Type Breakers have effective power and performance if you prefer economic investment. They can be operated comparatively at the higher back pressure than hydraulic type breaker.
Green Attachments' Piikki hydraulic breaker is designed for demanding demolition, earthmoving, and quarrying tasks that require precise yet powerful impact force. This high-quality hydraulic breaker is specifically optimized for breaking hard materials like stone, concrete, and asphalt, without subjecting the machine to excessive strain.

Detailed info on hydraulic breaker
A hydraulic breaker hammer is an essential tool for demolition, construction, and quarrying, and the Green Attachments Piikki series stands out with its powerful and reliable design. These demolition hammers are engineered to maximize productivity while ensuring operator safety and equipment longevity.
A key feature of the Piikki breaker is its extremely powerful impact, which maximizes performance and helps extend the lifespan of the machine it's attached to. This raw power is crucial for breaking through tough materials like concrete and rock with efficiency.
Despite its force, the breaker is designed for low vibration and noise, which is a significant benefit for operator comfort during long workdays. This also makes the tool suitable for use in sensitive urban environments where noise pollution is a concern.
The breaker's durable construction is built for the most demanding worksite conditions. It is manufactured from high-quality, wear-resistant materials to ensure it can withstand continuous, heavy-duty use. This robust build minimizes the risk of damage and unscheduled repairs.
Another practical advantage is the easy serviceability. Wear parts are readily and affordably available, and the hammer's design allows for quick maintenance, keeping machine downtime to an absolute minimum.
Finally, the Piikki breakers are known for their compatibility, with various size classes available to fit all excavator models. This versatility makes them a smart investment for businesses that operate a diverse fleet of machines.
In summary, the Green Attachments Piikki hydraulic breakers offers a simple yet reliable structure with powerful impact, enhanced operator comfort, and durability. Its cost-effective and low-maintenance design makes it a valuable asset for any professional in the field.

Tools and spare parts of hydraulic breaker
Conical tools are designed for everyday breaking applications. Their key characteristic is excellent material penetration, thanks to the conical design. Typical applications include:
- Concrete: Non-reinforced, thin, and also thicker floors, walls, and foundations.
- Sedimentary Rock (e.g., limestone, sandstone): Trenching, foundation work (in material with pre-existing fractures).
- Frozen Ground Applications
- Demolition Work
Green Attachments tools are manufactured from high-grade, hardened special alloy steel. Our extensive experience in heat treatment guarantees a deep and effective hardening process.
Tool Selection
Penetrative Breaking In penetrative breaking, a conical or chisel tool is forced into the material. This method is most effective when the material is: soft, stratified, plastic, or has low-abrasive properties.
Impact Breaking In impact breaking, the material is fractured by transferring powerful mechanical stress waves from the tool into the object. Impact breaking is most effective for hard, brittle, and highly abrasive materials. Large breakers have high impact energy and are excellently suited for this method. If a conical tool is used on hard material, the sharp tip will heat up and wear out very quickly.
Correct Tool Operation
- Use the hydraulic breaker only for fracturing rock, concrete, and other hard materials.
- Always keep the breaker tool perpendicular to the surface. Keep the downward pressure and the breaker tool aligned. If the object moves or the surface fractures, correct the working angle immediately.
- Do not strike a single spot for more than 15 seconds at a time. If the object does not break, stop the breaker and change the tool's position.
- When the tool is used in one spot for too long, a layer of rock dust forms underneath it. This dust dampens the impact force and also generates heat, which can lead to the deformation of the tool tip.
- Listen to the operating sound of the breaker. If the sound becomes higher-pitched or the impact force seems less effective, the tool is incorrectly positioned. This can also mean there is insufficient downward pressure on the tool. Reposition the tool and press it firmly against the object.
- Do not strike and pry with the tool at the same time, as this may cause the tool to snap. Rocks in hard or frozen ground can exert prying forces on the tool. Be cautious and stop breaking if you feel sudden resistance under the tool.
- Do not use the tool to move rocks. The lower part of the breaker housing is designed for repositioning boulders.
- Do not use the tool as a lever after it has penetrated concrete, rock, or hard ground. The tool may bend and/or break.
- Blank firing can destroy the breaker's most critical components, starting with the tool and the tool retaining pins. Avoid blank firing!
Frozen Ground Applications
A hydraulic breaker is an effective way to break frozen ground, especially the surface layer. However, if there are electrical or other cables within the frozen layer, it is nearly impossible to avoid damaging them. Breaking can also cause vibrations and cracking in nearby buildings. The advantage of using a breaker is that the excavated material is broken into smaller pieces compared to using a ripper, for example. This reduces the material's swell factor, leading to lower transportation costs.
Avoiding blank firing can sometimes be difficult in frozen ground applications, as the fractured structure may contain voids into which the tool can suddenly sink.
