GENERAL FAQs
What’s the difference between a rock-breaker, a hydraulic hammer, and a percussion hammer?
Nothing. It’s a potato-potahtoe thing. Some people like to say rock-breaker, some prefer hammer. We don’t mind what you call them – just as long as when you need something to bust rocks and concrete, you call us.
What size jobs are heavy-duty rock breakers best suited to?
Engineered for mid to heavy duty jobs, from major demolition to continuous hard rock breaking, our heavy-duty rock breaking range is built to withstand the tough stuff.
What type of materials can heavy-duty breakers handle?
Hard rock, reinforced concrete and high-production quarry material. Their hydraulic systems deliver consistent impact energy – the workhorse you need for the big jobs.
What size excavators do DEMCO heavy-duty breakers run on?
Depending on the model, they fit carriers from around 6 tonnes up to the largest excavators. DEMCO suppliers can ensure the right match.
What advantages do heavy-dutybreakers offer for heavy-duty work?
They provide high, consistent impact energy, even under continuous operation. Lower operating pressure reduces stress on the carrier and fuel use, while a large accumulator and hard-wearing design extend service life.
PILE DRIVING FAQs
Can DEMCO rock breakers be used for pile driving?
Yes, select DEMCO breakers can be fitted with post tool attachments for posts, guardrails and light civil piling.
What size excavator is needed for breaker-based pile driving?
Attachments suit carriers from around 1 tonne to large excavators, depending on the pile size and breaker model. Larger hammers are recommended for driving larger and longer piles.
Are rock breakers accurate for pile driving?
Yes, for fencing or light civil piles. However, they are not a substitute for heavy structural piling systems.
Is it cost-effective to use a rock breaker for pile driving?
Using a multi-purpose breaker lets operators perform both breaking and piling without buying extra attachments.
Maintenance &
Warranty Info
MAINTENANCE
How do I store my rock breaker?
Keep it in a dry environment. If stored outdoors, position the chisel end low and the hitch end elevated to prevent moisture entry. Proper storage avoids internal corrosion. Keep in mind that long-term exposure to moisture increases the risk of internal corrosion inside your attachment.
Can I leave a rock breaker outside?
Short-term outdoor storage is acceptable if the breaker is stored with the chisel end pointing downhill. For long-term storage, indoor or properly sheltered conditions are recommended to reduce the risk of internal corrosion.
How do I select the correct size rock breaker for my excavator?
Breaker selection needs to account for carrier operating weight, hydraulic flow rate, working pressure and allowable back pressure. Specification tables can be found on the DEMCO website and DEMCO suppliers are always happy to help out with selecting the right sized rock breaker for your machine.
What routine checks are important before and after using a breaker?
Operators should regularly inspect tool wear and check hoses and fittings for any leaks. Regular greasing is a must, as is ensuring hydraulic flow and pressure settings are verified. Early inspection and detection of any minor issues, prevents any major issues cropping up in the long-term.
Why has the breaker impact weakened?
Common causes include low nitrogen charge, high back pressure, restricted couplers or worn seals. Proper hydraulic testing is needed to pinpoint the issue.
How can I be sure my breaker is working to full capacity?
Check nitrogen pressure, supply-line pressure, return-line back pressure, and flow rates. Accurate measurement ensures consistent performance.
What does frequency loss with heavy blows indicate?
Usually excessive back pressure, which slows piston return and reduces blow rate. Inspect hoses, any partially closed valves and couplers to correct.
WARRANTY AND SERVICE
What warranty coverage is available for DEMCO rockbreakers?
All breakers come with a three-year manufacturer warranty and access to a dedicated service network in your local area, including parts, service and technical assistance.
How long will I have to wait for new rock breaker parts?
Service kits, wear parts, seals, bushings and tools are held locally for quick dispatch when you need them. Shipping time will depend on your location.
How often does a rock breaker need to be serviced?
Daily inspections are a good maintenance habit to get into, along with regular greasing. Compact breakers also require a nitrogen pressure check at least once a year to maintain performance.
