Cushion Chamber: It is an 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.

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.

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: It has 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 Pistion: It gives more powerful impact energy and brings a stable breaker operation.

Dual Oval Retainer Pins are robust and guarantees correct tool aliignment and long life.

50/50 Piston to Tool Weight Ratio efficiently transfers blow energy into the material and reduces recoil.

Breaker body

TNB-Hydraulic Breakers Features●Advanced accumulator free technology enables simple structure yet efficient.●Simple design allows less parts and realizes low running cost.●Adaptable for wide range of oil pressure and flow.●Auto grease system as optional.（TNB-7J, 151LU2, 230LU2, 310LU1, 400LU2, and 80K）

New design for the Bracket Adapter with enforced rigidity using thicker material.

Durable Guide Plate with a collar of bolts to avoid bolts shearing.

Auto Grease System as optional.

Hard Urethan Core to hold a distance between cylinder head and bracket adapter.

New Windows to check the marking for slack of side bolt nuts.

High and Low-Pressure Oil Port for driving a retrofit Auto-grease.

The Key to hold breaker body and the urethan sandwich system absoorbs the vibration of breaker body.

About TOKU Auto Grease System-Utilizing hydraulic high-pressure oil from base machine, TOKU Auto Grease System automatically supplies appropriate amount of grease to hydraulicbreakers during breaker operation.

Saving time for greasing!

Benefit of TOKU Auto Grease System-By supplying appropriate grease to the breaker all the time during breakeroperation, the wear of most consumable parts such as chisel bushing andretainer pins could be minimized, which extends lifetime of spare parts andreduces hydraulic breakers running cost.

Reducing the running cost of hydraulic breakers!
