Whether you’re tearing out a reinforced concrete abutment, scaling a tunnel, or running a pedestal-boom at the quarry, Komatsu hydraulic breakers provide superior impact energy for exceptional performance in a variety of rock and concrete demolition applications. The high impact power of the JTHB Series breakers is delivered through a combination of hydraulic and nitrogen gas energy, with no need for an accumulator. This same nitrogen gas design provides recoil absorption to minimize shock to the system while storing energy for the next blow, for less machine stress and fatigue and a more enjoyable operator experience.
High impact energy: A combination of 70% nitrogen gas and 30% hydraulic energy provides powerful impact for high-performance productivity.
Simple control valve: Flow-through design for efficient control with a minimal hydraulic surge.
Nitrogen gas cushion: Absorbs piston recoil to reduce vibrations for less stress on the machine and operator.
Dual retainer pins: Ensures proper alignment and spreads wear, for a longer chisel and bushing life.
Patented tie-rod design: Short, fully-enclosed tie rods with internal vibration dampeners and patented thread design resist standard wear and tear.
50/50 piston-to-chisel weight ratio: With long stroke for greater energy transfer and less recoil.
Special hardened alloy points: Increases durability in a wide range of applications.
Hydraulic cushioning: Helps to prevent damage caused by inadvertently triggering a “blank” fire.
”Accumulator-free” technology: Less maintenance, increased reliability and durability – and lower operating costs.
Underwater application port: Standard on all breakers, for a quick and convenient pressurized air connection.
Auto-lube options: Easily post-fitted, it eliminates time wasted on manual greasing and ensures correct and continuous lubrication.
Extensive tool range: For use in a large variety applications.
Environmentally friendly: Box brackets with noise-reduction design – minimally invasive in urban areas.
Fewer parts: Up to 30% fewer parts than competition for reduced operating costs and less maintenance.
Simple design, longer life: With only 2 moving parts and a built-in dust prevention system, you get maximum uptime and reliability.
