2020 Furukawa Rock Drill Large Series High-Performance Breakers Fx770 Qtv

Even though it requires the same pressure and flow than its predecessor, the Fx770 is designed to produce increased impact as a result of a significant increase in backhead pressure. It is also able to work on a wider range of carriers (48.5-ton to 83-ton).

This breaker is the perfect choice for working in quarries, breaking hard rock or taking on large demolition jobs. Several improvements to the through bolts increase durability, while a replaceable cylinder liner with concentric porting increases tool life. An anti-idle blow feature increases durability and performance. There is a coating applied to the breaker’s cylinder liner and valve, which reduces time-consuming maintenance and greatly increases the level of reliability.

Features may include:

• Increased carrier range (48.5 to 83 ton) over its predecessor, the F70 Qt (48.5 to 77 ton), allowing use on a wider range of carriers

• Larger diameter working steel (7.48?) over the F70 Qt (7.09?)

• Higher backhead pressure increases impact by 10% over the F70 Qt even though both operate with the same pressure and flow

• Replaceable cylinder liner with concentric porting keeps piston aligned for maximum impact performance

• Scratch-resistant phosphate coating applied to both valve and cylinder liner improves service life of both components; minimizes opportunity of minor galling

• Design improvements to the through bolts, including larger thread diameters, can increase durability by 20%

• Includes two-year warranty with registration
