Environmental pollution,
precautions
NOTICE Environmental pollution due to hydraulic
oil
Hydraulic oil is permanently environmentally
harmful. Escaped hydraulic oil will lead to
groundwater and soil contamination. Organisms
may die.
►Collect any hydraulic oil which escapes to avoid
environmental pollution. For minor volumes use
an absorbing medium (in case of an emergency
use soil). In case of major leakages contain the
hydraulic oil. It must not drain off and penetrate
the ground or enter the water table or water
supplies.
►Collect contaminated absorbing medium or soil
in a watertight box/container and close it tight.
►Contact an authorized waste management
company.
►Dispose of all contaminated material in
accordance with the applicable environmental
regulations.

Function
The operation of a transverse drum cutter is
described in a simplified version below:
The transverse drum cutter is an attachment for
hydraulic carriers. The cutter drums are powered
by the hydraulic motor and the gear of the
transverse drum cutter. The round attack picks are
attached to the cutter drums at a defined angle. A
rotating motion of the cutter drums facilitates the
cutting process and thus reduces the size of the
rock.
Modules
Cutter drums
The transverse drum cutter is equipped with one
left and one right cutter drum. These cutter drums
are fastened by means of screws and special
clamping sleeves directly to the drive shafts. A
certain number of pick boxes are attached to the
surface of the cutter drums. These hold the round
attack picks in position.
The cutter drums can be designed with charging
spirals (see arrow).

Transport lug
E
The transport lug (E) serves as an anchor point for
the lifting gear when transporting the transverse
drum cutter.
Rotatable upper part
The transverse drum cutter is fastened to a
suitable adapter plate on the carrier boom via the
rotatable upper part. The rotatable upper part is
bolted to the adapter plate. Additionally, the
transverse cutter drum can be rotated via the
rotatable upper part relative to the axis of the
boom.
Gear housing
The gear housing contains a spur gear driven by a
hydraulic motor. The gear's drive shafts turn the
cutter drums. The hydraulic motor transfers the
drive moment through the gear to the cutter drums.
Round attack picks
The round attack picks are made of steel and have
a brazed tungsten carbide tip. The round attack
picks are held in the pick boxes.
The appearance of the round attack picks may
deviate from the image shown here.
