Product Features
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.
