RB Open type hydraulic breaker
‌‌Option: ABF (Anti Blank Firing) System

Product details

 Open Heavy-duty Housing  Type (T version)
RBH-T adopts the nitrogen gas operating method.
‌It is designed to operate fewer restriction areas and 
no restriction of noise regulation place.
‌We offer a wide range of models with different capacities, ranging from  5tons to 50tons (RBH40 to RBH550) for mini-loaders, backhoes,  and excavators.

ABF system abstraction
Hydraulic breaker is an attachment that uses hydraulic energy generated from the excavator to strike the upper part of the chisel through the up-and-down reciprocating motion of the piston. It is a device that applies continuous impact, and in the case of a secondary crushing workshop, empty strikes occur frequently, which may cause cracks or breakage of the front head and chisel pins, which are the breaker's chisel support parts. Therefore, in order to solve this problem, the ABF system that prevents an empty striking from occurring by immediately changing the flow path when an empty air occurs is called an ABF (Anti Blank Firing) system.

 Accumulator Built Choice  Less stress to hydraulic components as absorbing pressure fluctuation.
Increase efficiency by replenishing short oil flow.

Valve System more efficient than other breaker's valve keeps cooler and makes the quicker and harder hitting.
Own design & Technology  All breaker models are developed by own technology
The best technology and manufacturing standards ensure that RBH BREAKERS are of the highest quality; ready to work on material that requires a hammer/breaker.
The factors that determine the quality and operating life of a hydraulic breaker are as follows.
Metallurgy (the best combination): 
Hydraulic breaker main materials is a special steel that alloys Ni, Cr, and Mo, so RB uses
the best quality of Made in Korea steel.

Heat treatment know-how
We work in a company specializing in heat treatment with over 40 years of experience in Korea.
Tolerance know-how: 
Before assembling each part of the hydraulic breaker, apply the best assembly tolerance to maintain the best quality.
