Series: Qtv | Energy: Approx. 12,000 J | Carrier: Approx. 110,000–154,000 lb (50–70 t)
The Furukawa Fx800 is a hydraulic hammer built for contractors, rental fleets, demolition crews, quarry operators, and equipment owners who need a breaker that fits their carrier correctly and delivers reliable output in the field. This model sits in the large Qtv range and is well suited for primary rock breaking, quarry operations, large-scale demolition, oversize reduction, and high-output production applications on large excavator platforms. When a breaker is matched correctly to the carrier — by weight class, hydraulic flow, and operating pressure — operators get better production, less unnecessary vibration transmitted back to the machine, reduced wear on the attachment and bracket, and fewer problems with hoses, bushings, retainers, and seals.
The Furukawa Fx800 is positioned in the large excavator class with an approximate service weight of 10,800 lb (4,900 kg) and an energy class of approximately 12,000 J. The tool steel diameter is approximately 7.5 in (190 mm). Oil flow and pressure requirements are matched to large excavator auxiliary circuits in the 50–70 t operating weight class. These specifications define where this breaker fits in the lineup. A unit that is too small for the job will force the operator to work the tool harder than intended, causing overheating and premature wear. A unit that is too large for the carrier can create excess hydraulic heat, damage mounting hardware, and shorten the service life of both the hammer and the machine.
Maintenance discipline is as important as correct sizing. A hydraulic hammer operates in some of the most demanding conditions on a jobsite — dust, shock load, side load, heat, moisture, and thousands of impact cycles per hour. Even a well-built breaker will lose performance if the lower bushing wears undetected, the tool is run dry, the seals harden from heat cycling, nitrogen or accumulator pressure drifts out of specification, or hydraulic flow and pressure fall outside the recommended range. Owners should inspect the tool steel, retainers, bushings, tie rods, hoses, fittings, and the grease system on a regular schedule. A properly maintained hammer hits harder, runs cooler, and protects the carrier better than a neglected one. For many contractors, the real value of this model is not the purchase price alone — it is the ability to keep it running through repairable wear rather than replacing the whole breaker.
The design characteristics of the Furukawa Fx800 include the Furukawa Qtv-series tie-rod-free monoblock design, high-energy power cell, and a robust lower section built for sustained production work on large excavators in quarry and primary demolition applications. These attributes make it well suited for applications where productivity, controllability, carrier protection, and access to service support all matter. When comparing this model against similar breakers, pay close attention to carrier size match, hydraulic circuit setup, tool steel availability, and the parts support network available in your area. Matching the hammer correctly to the carrier improves efficiency and helps prevent common issues such as weak hitting, slow cycling, tool overheating, premature bushing wear, and cracked mounting hardware.
HBS provides complete support for the Furukawa Fx800, including hydraulic hammer repairs, full rebuilds, routine maintenance, and sales. Parts stocked and available for this model include chisels, tie rods, upper and lower bushings, retainer pins, accumulator diaphragms or membranes, hydraulic seals and seal kits, front head components, and hoses and fittings. Whether this breaker is leaking oil, hitting weak, cycling slowly, overheating, wearing tools too fast, breaking retainers, or due for a full overhaul, HBS can diagnose the issue and return it to working condition. Contact HBS for service pricing, parts availability, rebuild options, and expert guidance on matching this hammer to the right carrier and application.
Key Features
- High-energy output in the approximately 12,000 J class positions the Furukawa Fx800 for primary rock production, large-scale quarry breaking, and oversize reduction applications where large excavators need per-blow energy that can fracture competent rock in a single pass rather than multiple attempts
- Furukawa Qtv-series monoblock construction eliminates external tie rods from the structural load path, reducing the risk of tie rod fatigue failures in high-shift production environments where shock load intensity is highest and external fastener fatigue is a common maintenance issue on conventional designs
- Large-diameter tool steel and extended front head assembly are engineered for the penetration force and side-load resistance required in primary quarry and demolition work, where the tool must maintain alignment and energy transfer efficiency under the angular contact forces common in oversize rock and reinforced concrete breaking
- HBS stocks parts for the Furukawa Fx800 including chisels, tie rods, upper and lower bushings, retainer pins, accumulator components, hydraulic seal kits, front head parts, and hoses — supporting repairs, rebuilds, and preventive maintenance without extended wait times
