FHB20 QTV LARGE SERIES HYDRAULIC ROCK BREAKERS FOR 19–26 TON EXCAVATORS – IMPROVED DURABILITY

The FHB20 Qtv is FRD’s fifth-generation breaker, with the Quick Switch Valve as standard, designed for excavators in the 19 to 26 ton range, the FHB20 Qtv is a hard-hitting rock breaking hammer that is a perfect choice for quarry and construction applications.

Incorporating the latest in design technology, the FHB20 Qtv hammer improves day-to-day performance, offering less maintenance and downtime, smoother operation, superior strength and the highest level of reliability.

Operators appreciate performance features that include a new valve design to reduce hydraulic fluid temperatures. A redesigned piston enhances surface contact to working steel, while a larger bushing surface keeps it aligned for greater impact. A replaceable cylinder liner increases tool life and reduces repair downtime.

  • Quick Switch Valve for changing stroke length, standard

  • Solid, square body design for strength and rigidity with no thru-bolts to torque, break or replace
  • Replaceable cylinder liner with concentric porting that keeps the piston aligned
  • Complete With Our Exclusive Pro-Pak
  • Three-point dust intake prevention: piston grooves, a cushion ring and improved external sealing
  • New valve design that reduces hydraulic fluid temperature
  • Lubrication routed evenly to the thrust bushing, front bushing and rod pins

What is new in the FHB20?

The FHB20 Qtv includes features designed for superior strength and improved durability. Improved internal grease routing now provides more direct lubrication to select components with inline grease fitting for easier access. The relocation of the air inlet for the patented dust intake prevention system allows it to take in air from the top of the breaker, creating a dust-free environment for cleaner, more reliable operation.

Our unique design gives us an excellent power to weight ratio for lower maintenance and increased performance. This solid body concept eliminates thru-bolts which has reduced the breaker weight but does not affect our impact energy. This makes for much better control for the operator, less wear and tear on the excavator and reduced fuel costs.

The FRD FHB20 is a hydraulic breaker for excavators in the 19 to 26 U.S. ton class, with 20 tons as the optimal carrier weight. It weighs 3,485 lb (1,584 kg), runs on 33.1 to 51.4 GPM at 2,320 to 2,610 psi, and delivers 390 to 590 blows per minute through 5.31 in (135 mm) working steel. The Quick Switch Valve for changing stroke length is standard, and the solid body has no thru-bolts.

The FHB20 ships in FRD’s Qtv cradle, a low-noise protective housing that accepts a wide range of top caps. The FHB Series builds on FRD’s Fx Series and adds the Quick Switch Valve, updated stop pins and rod pins, a three-point dust intake prevention system, and a valve design that lowers hydraulic oil temperature.

All FRD USA breakers come complete with exclusive Pro-Pak for ease of installation. The Pro-Pak includes hose whips, mounting hardware, standard working steel and tool kit with operating manual at no additional charge.

FREQUENTLY ASKED QUESTIONS

The FHB20 is sized for carriers from 19 to 26 U.S. tons, with 20 tons as the optimal carrier weight. Confirm that the carrier’s auxiliary flow and pressure fall within the FHB20’s range before mounting.
The FHB20 weighs 3,485 lb (1,584 kg) and is 113 in (2,870 mm) long. Both figures include the standard working steel and universal top cap, less mounting pins and bushings.
The FHB20 accepts 33.1 to 51.4 GPM (125 to 195 LPM) of oil flow at 2,320 to 2,610 psi (160 to 180 bar). Hydraulic input power is 58.5 kW.
The FHB20 delivers an adjustable 390 to 590 blows per minute. It uses 5.31 in (135 mm) diameter working steel.
The Quick Switch Valve (QSV) is the FHB20’s stroke adjuster and comes standard. Turning the valve with a tool selects one of three settings: L for long stroke, S for short stroke, and A for long stroke with anti-dry-fire protection.
The Quick Switch Valve (QSV) is the FHB20’s stroke adjuster. The operator turns the valve with a tool until its groove lines up with one of three letters.
No. The Smart Stroke System, which changes stroke length automatically by sensing piston position, is an option on the FHB27 through FHB45 only. The FHB20 sets stroke manually with the Quick Switch Valve.
No. The FHB20 uses a solid body design that eliminates thru-bolts, so there are none to torque, break or replace.

Choosing the Right Hydraulic Breaker

When operated properly, breakers efficiently and effectively break up concrete and shatter rock. If not operated properly or not sized correctly for the job, the attachment can fail unexpectedly and waste precious time on a job site, or even suffer a reduced lifespan.

Guide for the Fx225 Qtv Large Series rock breaking hammers from Furukawa / FRD are available in a variety of mounting configurations & are designed to tackle the most difficult of construction & excavation projects.
