This guide explains key features, technical considerations, procurement criteria, and lifecycle costs to help procurement managers, fleet owners, and site supervisors make an informed purchase decision.
Why choose an excavator hydraulic breaker for Furukawa 18-21t machines
Matching an excavator hydraulic breaker to a Furukawa 18-21 ton machine ensures optimal energy transfer, carrier stability, and tool performance. Excavator hydraulic breaker selection affects productivity, fuel consumption, and wear-part costs. The HB20G is designed to integrate with the hydraulic flow and pressure profiles common to Furukawa 18-21t excavators, offering a balance of blow energy and blow frequency suitable for medium demolition, rock breaking, and trenching tasks.
Key specifications and compatibility
Before procurement, verify mechanical mounting, hydraulic flow, operating pressure, and mass distribution. The table below compares typical values for the HB20G against a Furukawa OEM mid-weight breaker and a generic competitor in the same class. Values are representative ranges intended for procurement evaluation; confirm exact data with manufacturer technical sheets prior to purchase.
| Parameter | Huilian HB20G (typical) | Furukawa Mid-weight OEM (typical) | Generic 18-21t Class Breaker (typical) |
|---|---|---|---|
| Recommended Carrier Weight | 18 - 21 tonnes | 18 - 20 tonnes | 16 - 22 tonnes |
| Operating Pressure | 160 - 210 bar | 160 - 220 bar | 150 - 220 bar |
| Hydraulic Flow Requirement | 80 - 140 L/min | 85 - 145 L/min | 70 - 150 L/min |
| Impact Energy | 1500 - 2100 J | 1400 - 2200 J | 1300 - 2100 J |
| Blow Rate | 300 - 800 bpm | 280 - 820 bpm | 250 - 800 bpm |
| Approx. Breaker Weight | 1200 - 1600 kg | 1100 - 1700 kg | 1000 - 1700 kg |
| Tool Diameter | 70 - 140 mm (varies by chisel) | 75 - 140 mm | 65 - 140 mm |
Performance metrics explained for procurement decisions
Understanding key performance metrics helps match the excavator hydraulic breaker to your tasks. Impact energy indicates the force delivered per blow and correlates to breaking ability on hard rock. Blow rate (bpm) influences how many impacts occur per minute; higher bpm with lower energy suits fracturing and concrete demolition, while lower bpm with higher energy is better for hard rock. Effective productivity is a function of impact energy multiplied by practicable bpm for the material type.
Other important metrics include carrier hydraulic compatibility - the breaker must operate within the carrier's maximum pressure and flow to avoid loss of performance or hydraulic damage. Heat generation and hydraulic oil cleanliness requirements also affect long-term reliability.
Mounting, hydraulics and installation considerations
Proper mounting and hydraulic integration are critical to realizing the performance of an excavator hydraulic breaker. Key steps:
- Confirm bracket dimensions and pin centers match Furukawa boom adapter or provide an adapter kit. Improper mounting increases vibration and reduces productivity.
- Install a dedicated hydraulic circuit with correct relief and flow controls. Use accumulator or anti-blank firing devices if recommended by the breaker manufacturer.
- Fit a flow control valve or a chisel retainer per manufacturer guidance. Ensure hydraulic hoses are rated for the breaker pressure and routed to minimize abrasion and heat exposure.
- Consider mounting dampers or vibration isolators to protect the carrier cab and electronic components.
Maintenance, wear parts and service intervals
Routine maintenance keeps the excavator hydraulic breaker productive and reduces downtime costs. Crucial maintenance items include daily greasing of the tool and bushings, checking nitrogen pre-charge where applicable, monitoring hydraulic oil cleanliness, and inspecting hoses and fasteners. Replace the tool steel and bushings according to wear limits; using hardened tool steel from OEM or certified suppliers extends tool life on abrasive rock.
Recommended maintenance schedule (example):
- Daily: visual inspection, lubrication of tool and piston guide, check hydraulic fittings.
- Weekly: check retaining bolts, condition of hoses, and chisel alignment.
- Every 250 operation hours: inspect piston and bushings, check accumulator pressure if equipped.
- Every 1000 operation hours: comprehensive service including seal replacement and flow testing.
Applications and jobsite selection for HB20G
The HB20G suits a wide range of medium-duty tasks where Furukawa 18-21t excavators operate. Typical applications:
- Quarry secondary breaking and boulder reduction
- Concrete demolition for foundations, retaining walls, and road work
- Trenching in hard ground with embedded rock
- Site clearance where controlled fragmentation reduces explosives use
For each application, match breaker energy and tool type. Use moil points for general breaking, chisels for concrete and cutting, and blunt tools for recycled concrete where rebars are present.
Procurement checklist: essential questions before you buy an excavator hydraulic breaker
Use the following checklist to avoid common procurement pitfalls and to ensure the HB20G or equivalent breaker meets operational needs.
- Is the breaker officially rated for your Furukawa 18-21t excavator hydraulic flow and pressure?
- Does the supplier provide mounting adapters or detailed mounting drawings?
- Are spare parts such as tools, bushings, and seals readily available locally?
- What warranty and service response times does the manufacturer or dealer provide?
- Are recommended hydraulic oil grades and maintenance intervals documented?
- Does the breaker include protective features such as anti-blank firing, accumulator, and integrated shock absorption?
- Can the supplier provide case studies or references for similar applications?
Cost of ownership and return on investment
Initial purchase price is only part of total cost of ownership. Consider fuel savings from faster cycle times, reduced downtime from reliable components, and the cost of wear parts. The simplified table below shows an illustrative cost breakdown comparing two procurement scenarios. Numbers are hypothetical and intended for planning; obtain real quotes for budgeting.
| Cost Item | Huilian HB20G (example) | Generic Competing Breaker (example) |
|---|---|---|
| Initial Purchase | 40,000 USD | 32,000 USD |
| Annual Wear Parts & Service | 6,000 USD | 8,500 USD |
| Average Productivity (m3/day) | 20 | 16 |
| Estimated 3-Year Total Cost | 58,000 USD (with higher productivity) | 57,500 USD (lower productivity) |
While a generic breaker may have a lower purchase price, improved uptime, parts longevity, and higher productivity from a well-matched breaker like the HB20G can deliver better lifecycle value. Calculate ROI by factoring daily production increase, reduced downtime, and parts replacement cadence.
