TRENCHER
ATR 90
13
Noise and Vibrations
This trencher is not equipped with own combustion engine. As an implement it is
intended for coupling to a carrier and any noise emissions of this machine depend
only on the used carrier type according to its power unit and technical condition.
Technical Description
The trencher ATR-90 is designed for coupling to a carrier fitted with a
corresponding clamping plate.
Trenching Device
This device consists of a link chain running on a special bar. The chain links hold
tips that cut the soil and bring it to an auger. Above the bar there is a guiding block
which helps keeping flatness at trenching. It serves also as a fixed point at
displacement of the machine. The auger puts the soil aside, approximately 15 cm
from new trench.
The chain bar is height-adjustable according to the carrier actually used. Its
hydraulically controlled continuous adjustment can provide trenches in depths as
from 60 cm to 90 cm. The guiding block for flat trenching is mounted close to the
chain bar edge. The chain tips are fitted as left and right and intended for cutting the
soil and bringing it to the auger.
Fully hydraulic control of the machine, i.e. the link chain and the auger, is based
on the carrier hydraulics according to the carrier actually used.
This hydraulic system is designed for power transmission from the carrier engine
to the working parts of the trencher. It comprises also hydraulic hoses, quick-acting
couplers and hydromotor
.
