1. DEFINITION & PHOTO
2. ADVANTAGE
The advantage of SHD
Noise Low noise but accurate hitting
Power Similar to the power of SUSAN SP3, but 30% faster
Nitrogen pressure ACC gas pressure
High (47kg/cm2) low (4kg/cm2)
Hydraulic pressure The varying of hydraulic pressure is low
(max. 165kg/cmm2)
Repelling power The low vibration help an operator not to get tired
because the drifter is stable. Moreover, you can save
the fuel and there are no doubt of sub line loss.
Temperature The oil pressure is hardly going up to 65 degree in
spite of long time operation.

1) ACCUMULATOR (LARGE CAPACITY)
- Reinforced packing to protect oil leakage.
- Identify high pressure with low pressure.
(Enable to connect low pressure with high
pressure if urgent)
- Efficient design by varying external form.
- Easy connect each bodies with screw.
2) REAR COVER (COST EFFECTIVE)
- Shorter length but larger capacity than before
- Internal air drain design
- Cost-effective application
4. CHARACTERISTIC
3) CONTROL VALVE (UNIQUE CIRCUIT DEVELOPMENT) - The circuit of control valve , cylinder body are different from the
existing (SOOSAN, FURUKAWA, etc.)
- Exclusive high efficient control valve system
(Not to hit up & down side in the valve housing)
(No bolt broken & burning problem)
- Keep existing advantages but get rid of most problems.
- Preparing the patent
- Independent valve system with guide in the valve box
4) PISTON (CREATIVE DESIGN) - Creative design
- Exact center of gravity
(accurate hitting performance)
- Efficient hitting method
(hitting part hit the head of Rods exactly)
4. CHARACTERISTIC
5) FRONT COVER (EASY FLUSHING) - Varying circuit for easy flushing
- Remove the notch
- The reinforcement of wear resistance
(use special material in bearing)
6) THE OTHERS - Modularizing supplies
- The FRONT COVER parts are standard and
compatible with FRONT COVER to get easy.
- Use authentic PACKER seal kit
(Seal kits attached VALVE HOUSING & CYLINDER are upgraded
for durability.)
- Competitive external form design
(Simple, smooth, effective) (Adjustment for proper ratio)
(The top of motor moved on upper side)

- The control valve of drifter will have 2 kinds of model (internal
type, external type) which is same form but different capacity.
- Rotation gear will be designed clutch type.
- The connection flushing part to hitting part will be designed 2
types.
- Damping housing will be applied to improve labor pain and
hitting power.
