EDER splitting device EHG80, 07.12.09 - 1 -

Technical Data

Splitting way (range) 200 mm
Wedge length 180 mm
Wedge strength 120 mm
Laceration in diagonal position up to 220 mm
Pressure at the wedge 7,500 kg
Weight of the splitting device 16 kg
Required oil pressure 150 bar
Required oil flow from 10 l / min

Areas of Application

The device is apt for splitting trunks regardless of length and diameter. The wedge is
driven into the trunk through the oil cock from the shell, while the counterpoise is
absorbed by the diagonal edge penetrating into the face surface of the trunk. With
fibered wood and long trunks, the device can be applied diagonally. So the crack can be
widened to 220 mm width at any frequency.

Connecting the Splitting Device to the Hydraulics

For assembling the splitting device to tractors, unimog or hydraulic aggregates, 2
hydraulic connections are required. It is to be observed that a connection should be
unpressurized (R = return). The other connection (P = pump) is inserted at the pressure
line.

There are various hydraulic systems on the market. At purchase, the hydraulic system to
which the splitting device is to be connected must be named to the manufacturer, so the
corresponding valves are assembled to the device. With hydraulic systems with
adjustable feed pump, an oil flow of 20 l/min is to be adjusted. At this flow rate, optimal
performance of the splitting device is achieved.

Instructions for Use

The front and back range of the wedge can be controlled via the control valve attached to
the handhold. The hose connexion serially 10 m long between the hydraulic drive and the
splitting device gives a sufficient scope of movement for the person operating the device.
By using the splitting device, splitting long or fibered trunks is essentially facilitated and
accelerated. The pieces to be split are trenched once or repeatedly lying in their
respective position at the bottom according to requirements. This device is also apt for
splitting up treetops.
