FHB18 QTV LARGE SERIES HYDRAULIC ROCK BREAKERS for 15–21 Ton Excavators – SUPERIOR RELIABILITY
This rock breaking hammer is FRD’s fifth-generation breaker, with the Quick Switch Valve as standard & designed for use on excavators in the 15- to 21-ton range.
The FHB18 Qtv is ideal for roads, bridges, rock, utility applications, and in quarries. Incorporating the latest in design technology, the FHB18 Qtv hammer improves day-to-day performance, offering less maintenance and downtime, smoother operation, superior strength and the highest level of reliability.

PERFORMANCE SPOTLIGHT
WHAT IS NEW IN THE FHB18?
The FHB18 Qtv offers improved durability, with features that include a square, mono-block body design for superior strength. A patent pending dust prevention system incorporates grooves to trap contaminates on the upstroke and expel them on the piston downstroke, while a cushion ring acts as a secondary trap. This improves the life of the piston, bushings and working steel.
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 repair downtime.
The FRD FHB18 is a hydraulic breaker for excavators in the 15 to 21 U.S. ton class, with 18 tons as the optimal carrier weight. It weighs 3,355 lb (1,525 kg), runs on 29.1 to 44.8 GPM at 2,320 to 2,610 psi, and delivers 400 to 600 blows per minute through 4.72 in (120 mm) working steel. The Quick Switch Valve for changing stroke length is standard, and the solid body has no thru-bolts.
The FHB18 Qtv is also designed to accommodate automatic lubrication systems for quick daily maintenance. 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 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.
