FHB35 QTV LARGE SERIES HYDRAULIC ROCK BREAKERS for 28–44 Ton Excavators – PERFORMANCE, STRENGTH AND RELIABILITY

FRD’s fifth-generation breaker, with the Quick Switch Valve as standard and the Smart Stroke System as an option. Designed for excavators in the 28- to 44-ton range, the FHB35 Qtv is a hard-hitting rock breaking hammer that has no rivals.

The FRD FHB35 is a hydraulic breaker for excavators in the 28 to 44 U.S. ton class, with 35 tons as the optimal carrier weight. It weighs 5,277 lb (2,399 kg), runs at 2,320 to 2,610 psi, and delivers 340 to 510 blows per minute through 6.10 in (155 mm) working steel. The Quick Switch Valve is standard, the automatic Smart Stroke System is optional, and the solid body has no thru-bolts.

FRD FHB35 hydraulic breaker for 28–44 ton excavators: 5,277 lb, 340–510 BPM, 6.10 in steel. Quick Switch Valve standard, Smart Stroke System optional.

PERFORMANCE SPOTLIGHT

  • Quick Switch Valve for changing stroke length, standard
  • Optional Smart Stroke System that switches stroke length automatically
  • Solid, square body design with no thru-bolts to torque, break or replace
  • Replaceable cylinder liner with concentric porting that keeps the piston aligned
  • 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
  • Larger bushing surface that keeps the working steel aligned
  • Updated stop pins and rod pins for longer service life
  • Qtv cradle for protection and sound suppression

What is new in the FHB35?

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.

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 time-consuming maintenance.

The FHB35 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, keeps its solid body without thru-bolts, and adds new stroke control, updated stop pins and rod pins, a three-point dust intake prevention system, and a valve design that lowers hydraulic oil temperature.

The FHB35 Qtv offers improved durability, with features that include a square, mono-block body design for superior strength. The elimination of thru-bolts also reduces maintenance and failure. Excavators equipped with quick couplers can take advantage of our Floating Top-Mount Boss mounting system. This incorporates standard mounting hardware while meeting “OEM Pin Centers” for specific carrier mounting eliminating the need for specific OEM top caps.

All FRD hammers come complete with our 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 FHB35 comes with the Quick Switch Valve (QSV) as standard and offers the Smart Stroke System (SSS) as an option. With the QSV, the operator turns the valve with a tool until its groove lines up with one of three letters.
The FHB35 is sized for carriers from 28 to 44 U.S. tons, with 35 tons as the optimal carrier weight. Confirm that the carrier’s auxiliary flow and pressure fall within the FHB35’s range before mounting.
The FHB35 weighs 5,277 lb (2,399 kg) and is 126 in (3,197 mm) long. Both figures include the standard working steel and universal top cap, less mounting pins and bushings.
The FHB35 accepts 44.8 to 56.6 GPM of oil flow at 2,320 to 2,610 psi (160 to 180 bar). Hydraulic input power is 75.0 kW.
The FHB35 delivers an adjustable 340 to 510 blows per minute. It uses 6.10 in (155 mm) diameter working steel.
The Quick Switch Valve (QSV) is the FHB35’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 Smart Stroke System (SSS) is available on the FHB35 as an option. It switches between long and short stroke automatically by sensing piston position. Without it, the FHB35 sets stroke manually with the standard Quick Switch Valve.
No. The FHB35 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.
