Cushion Chamber

Important impact source since TNB-breakers source its Impact Energy 70% from Nitrogen Gas Pressure of cushion chamber and the rest of 30% from the Operation Oil Circuit.

Auto Greasing System

New standard Auto Greasing System for models TNB-7J, TNB-151LU2, TNB-230LU2, TNB-310LU2 and TNB-400LU2

Accumulator Free Breaker Structure

Allows easy and low cost maintenance.

Dust Preventing Valve

Takes cleaner air from upper area into the impact chamber and blows out the dusty air to bottom. This valve port is also used for
Underwater Application to lead the high pressure air from a compressor.

Grease Supply

Direct and Independent Grease Supply to Chisel Bush and Chisel Holder Bush. A chisel is the most consumed item and this system contributes well for the long life of chisel.

Durable Side Bolts

Stress scattered structure and partially rubber coated for anti-vibration.

SHORT OIL PATH

The oil path between control valve and cylinder is taken shortest as less as possible to avoid any secondary trouble.

LONG STROKE PISTON

Gives more powerful impact energy and brings a stable breaker operation.

DUAL OVAL RETAINER PINS

Robust and guarantees correct tool alignment and long life.

50/50 PISTON TO TOOL WEIGHT RATIO

Efficiently transfers blow energy into the material and reduces recoil.
