Big things.
Small package.
Huge capability.
Small in size.
Big on performance.
Providing powerful demolition and recycling capability in a compact package, DEMCO’s mini multi-processors suit carriers from 1 to 7 tonnes. Its twin-cylinder, twin-pin design maximises crushing performance and maintains steady, controlled operation across a range of working angles. For minimal noise and vibration processing in smaller machines and tighter sites, they’re the best tool for the job.
Ease and efficiency
The dual cylinder design provides a wide opening, powerful initial force, and an optimised angle to approach the work. Independent cylinder movement minimises the stress to the carrier too, making ongoing operation as noise & vibration-free as possible.
Confident crushing
The mini multi-processor packs a lot of power and strength into a small package, making it a valuable tool for demolition and recycling contractors. Built to minimise noise & vibration on site while still delivering impressive force, it proves that ‘compact’ doesn’t mean ‘compromise’.
Adaptable application
For added productivity with less tools needed mini multi-processors can shear, crush, & cut in tight & tricky spaces. Some models also provide versatile interchangeable jaw & tooth design, providing added flexibility to ongoing use.
Built-tough build
Made from high-strength, abrasive resistant steel, along with a heavy-duty cylinder guard & hardened pin & T-bushing design, DEMCO mini multi-processors are built to last no matter what you throw at them.

GENERAL FAQs
Are DEMCO multi-processor jaws interchangeable?
Yes. DEMCO multi-processors are designed with interchangeable jaw sets and replaceable tooth systems to allow configuration for different demolition tasks.
How do the jaw changes actually work?
Bolt-on adapter systems with replaceable teeth and reversible cutting blades make switching from concrete to steel jaws fast and efficient.
What benefits does the multi-processor design provide?
Heavy-duty jaws, oversized pivots and interchangeable sets improve versatility and reduce maintenance costs. One machine can handle concrete, steel and pulverising tasks, maximising your return on investment.
Are DEMCO multi-processors easier to maintain?
Absolutely. Accessible service points, replaceable wear components and robust structural construction reduce maintenance time and extend service life under repetitive load conditions.
What is the difference between a multi-processor and a dedicated demolition attachment?
Multi-processors allow you to switch functions on site, while dedicated attachments are optimised for one task. Multi-processors offer flexibility without the need for extra units.
How does jaw geometry influence crushing performance?
Deeper jaws hold material better, while tooth placement affects penetration. Pivot position and jaw-tip leverage determine effective crushing force. Proper geometry balances bite and power.
What determines the cutting force of a steel jaw set?
Cutting force is influenced by hydraulic cylinder size, operating pressure and the mechanical leverage created by the jaw design. Correct setup ensures consistent force without stressing the structure.
Why are oversized pivot pins and bearings important?
Multi-processors are exposed to high torsional loads during demolition, particularly when processing uneven or reinforced material. Oversized pivot pins and bearings spread torsional loads evenly, reduce stress, maintain alignment and extend service life.
Will jaw interchangeability increase job efficiency?
Switching jaws allows a single attachment to cover multiple tasks, reducing capital costs and boosting on-site productivity.
What hydraulic setup is required for optimal performance?
Correct flow and pressure are essential. Too little slows the cycle time, while too much accelerates wear. Matching the attachment specifications correctly ensures reliable performance.
What are the early signs of structural wear in a multi-processor?
Excessive play in pivot points, uneven jaw alignment, abnormal vibration or visible cracking around high-stress areas may indicate wear. Regular inspection of pins, bushes and cylinder mounts helps prevent structural damage and costly rebuilds.

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.
