JTHB seriesLarge Range

High impact energy

A combination of 70% nitrogen gas and 30% hydraulic energy provides powerful impact for high-performance productivity.

Simple design, longer life

With only 2 moving parts and a built-in dust prevention system, you get maximum uptime and reliability.

Fewer parts

Up to 30% fewer parts than competition for reduced operating costs and less maintenance.

Environmentally-friendly

Box brackets with noise-reduction design – minimally invasive in urban areas.

Extensive tool range

For use in a large variety applications.

Versatile with any carrier

Low sensitivity to back pressure means the Komatsu breaker can be used with virtually any carrier.

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.

Simple control valve

Flow-through design for effi cient control with a minimal hydraulic surge.

Dual retainer pins

Ensures proper alignment and spreads wear, for a longer

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-fi tted, it eliminates time wasted on manual greasing and ensures correct and continuous lubrication.
