JAB is Just
Attachment & Breaker

Improving Technique and Stacking
Know-how through developing various
breakers and attachments

Since 2003, JAB Co., Ltd. started production of Rock Splitter and had served local industry
for several years obtaining the best reputation. Since 2006, we've been manufacturing hydraulic
breakers in the newly expanded factory area of up-to-dated facilities in Incheon, Korea.
We, JAB Co., Ltd., are strongly committed to create maximum value for customer's satisfaction
by quality, service and performance. The maturity of quality system was validated in 2005, 2008
after it was certified to the ISO9001 and CE on our products.
JAB Co., Ltd. has a high level of technical competence both gas typed breaker(JB-Series) and
totally hydraulic typed breaker(RB-Series) to meet each customer's satisfaction in the world.

JB-Series (Silenced Box Type)

JAB Co., Ltd. says its new JB-Series breaker features nitrogen gas-assisted operation for improved
efficiency. Our soundproofing system is designed to prevent any damage caused by operating vibration
which could otherwise be detrimental to both carrier and breaker itself.

Special Features

Box typed housing design
Soundproofing system for downtown area under construction
Polyurethane buffers reduces noise and absorbs vibration
MC Nylon plates are designed for fit tight on surrounded four sides
Low recoil movements for operator’s safe condition
High impact energy & Low noise level
High performance ability & Low maintenance cost
Total 17 models of silenced type









JB-Series (Open Top Type)

Upper side of housing cover is stronger than other hammers with additional steel
bars. Also, lower side of housing cover is reinforced for wear resistance.

Special Features

Open typed housing design

RB-Series

The production of JAB Rock breaker is based on many years of experience and the
use of high quality material, which enables the equipment to resist the mechanical
and thermic stress occurring under normal working conditions.

Special Features

Acceptable for large range of flow
Wide Carrier Versatility
Easy operation for not only operator but also carrier
Decreasing maintanance cost with increasing life time
by reducing fiction of consumable parts
Low Recoil System for Carrier operator’s

Accumulator Ass’y
Membrane-type accumulators assist with power stroke and
provide protection against hydraulic impact while the sealed
nitrogen minimizes and guarantees constant production.

Pressure Regulator

Optimized Piston Design
To keep the most efficiency of power,
the piston is in contact with the
surface to the tool for energy transfer.
