Trencher coupling to a carrier Quick-acting clamping plate on
trencher
Any figuring as to coupling of the machine to a carrier is
informative only. The given way of coupling depends always on the
carrier actually used. To couple the machine to the carrier it is
necessary to follow the instructions as shown in the concerned manual to
the carrier!
- Lift up the safety pins on the carrier clamping plate.
- While coupling, hang up the clamping pins on the carrier clamping plate under
the hooks on the trencher plate.
- Lift up the carrier jib and let both plates come near. The trencher, resp. its chain
bar, should be approximately 20 cm above ground.
- Let both plates interlock and insert the safety pins of the carrier plate through
the holes on the trencher plate. They should go freely through the holes.
- Couple the hydraulic hoses to the corresponding couplers.
Trenching
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. To work in the required depth first set up a slider on the
machine used as a support to follow the ground while trenching. This slider is
mounted under the hydromotor and movable in its longitudinal grooves.
To set up the required depth proceed as follows:
-
Block the carrier properly against unwished motion and lift up the jib.
