Hydraulic breaker range overview
SB breaker range
SB hydraulic breakers are slim, compact and simple to handle, making them extremely versatile. Combining superior efficiency and performance with high reliability and serviceability.
Choose a SB hydraulic breaker as your partner for a huge range of tasks. Suitable for most carriers like excavators, backhoe and skid steer loaders as well as demolition robots, it will get the job done – quickly and economically!
Solid Body Breakers are perfect for demolishing light concrete structures and asphalt pavements.
MB breaker range
The MB range delivers reliable breaking power for demanding applications. Designed for medium‑size excavators, MB breakers combine high impact performance with intelligent protection for efficient, controlled operation.
MB breakers reduce wear, lower operating costs, and improve operator comfort through proven vibration‑damping technology.
HB breaker range
The HB range is engineered for the toughest breaking applications. Designed for heavy excavators, HB breakers deliver maximum impact energy with intelligent control, ensuring consistent performance in hard rock and reinforced concrete.
HB breakers combine proven durability with advanced protection systems to reduce wear, prevent blank firing, and maximize uptime.

History of the excavator hydraulic hammer
Hydraulic breakers are the oldest hydraulic attachments for carriers. The first serial manufactured rock breaker was the Krupp HM 400 in 1967 and the patent was secured in 1963. Excavator jack hammers are impact devices designed to break any kind of rock or concrete with any hardness or physical property. They have a wide range of applications such as demolition, deconstruction, primary rock excavation, secondary rock breaking, trenching, foundation work, asphalt cutting and many others.
Today, our excavator hydraulic hammers are available from ~ 50 kg to more than 10,000 kg of operating weight for any kind of carrier. Over sixty years of development of the breaker hammers has produced advances at different levels, such as self-lubricating systems, sound & vibration damped systems, automatic rock hardness adjusting systems, energy recovery, solid body concept and much more.

What is a hydraulic breaker?
|
A hydraulic breaker is a powerful excavator attachment designed to break rock, concrete, and other hard materials with precision and control. Powered by the carrier’s hydraulic system, it delivers repeated high‑energy impacts where brute force alone is not enough. Hydraulic breakers are engineered to help customers work faster, safer, and more efficiently—whether in construction, demolition, quarrying, or mining. |
How does a breaker work?
|
Hydraulic breakers convert hydraulic power into controlled impact energy. Pressurized oil from the carrier drives an internal piston, which strikes the working tool with consistent force. This cycle is repeated many times per minute, allowing material to be broken efficiently and precisely. What sets Epiroc apart is intelligent control. Advanced systems automatically adapt the breaker’s behavior to the material, delivering power only when needed. This protects components, reduces wear, and helps extend service life—without operator intervention. |
What are the main types of hydraulic breakers?
|
Light – SB breakers Best for lighter tasks like removing sidewalks, breaking up light concrete and asphalt. Medium – MB breakers Large – HB breakers |
How do I choose the right hydraulic breaker for my carrier?
|
Here are three key things to consider:
|
What maintenance is required for hydraulic breakers?
|
During a shift Monitor the filling level of the grease cartridge of the ContiLube® II lubrication system and immediately replace an empty cartridge. Monitor the lubricant film on the shaft of the working tool. Manual lubrication of the working tool approx. every 2 hours.
Daily Check the bolted connections at the adapter plate and tighten as required. Check the hydraulic lines for leaks. Check that the pipe clamps on the carrier are tight. Check the screw connections of the swivel joint covers and tighten as required. Replace damaged swivel joint covers.
For different types of breakes you need to consider different things. Please follow the instructions in the safety and operating instructions. TechInfo |
Can I use a hydraulic breaker underwater?
|
Using the hydraulic breaker in and under water is possible if it has been fitted out with special safety equipment. A special connection kit for underwater use was developed to avoid damage to the hydraulic breaker. It contains all the necessary components including the safety facilities to keep the interior of the lower breaker part free from water by using external compressed air. Specific documentation, has been drawn up, including operating instructions and a spare parts list, for underwater usage. Before using the hydraulic breaker in or under water, consult the Epiroc Customer Center / Dealer in your area. |
How do I properly store a hydraulic breaker when not in use?
|
The hydraulic breaker must be stored in an upright position to avoid its seals being damaged.
We differentiate between three time periods, short (less than 8 weeks), long (more than 8 weeks) and more than twelve month.
