2. Description
The machine is a radio-controlled, type MC 85 trench roller
with articulated steering.
The machine is composed of two separate halves which are
interlinked by a so-called articulated joint.
The front section houses two drums, an exciter, the diesel engine
and the hydraulic pumps. The diesel engine powers the pumps
used for the hydraulic system.
The rear section houses two drums, an exciter and the hydraulic
and diesel tank.
The machine is controlled with a radio remote control.
All functions of the roller (drive, steer, vibrate) are controlled hydrau-
lically. The parking brake engages automatically by spring force.
Located on the machine is a key switch that is used to activate
the receiver on the machine.
The machine
The radio remote control The machine is operated with the help of a radio remote control.
Since controlling the machine from a safe distance, the operator
is protected throughout operation. The operator can, for instance,
remain in a position above the machine to monitor and control it
while performing compacting operations in trenches.
The remote control furthermore comes with a safety shutdown system
which will stop the movement of the machine if the operator holding
the remote control moves closer than 2 meters to the machine or
moves away from it farther than 20 meters.
The radio system transmits signals to two receiver antennas which
are located below the hoods of the machine. Sent from the hand-
held transmitter to the antennas, the radio signals control the
machine. The machine can still be used as intended if only one
antenna receives the signal transmitted by the remote control.
Even it multiple machines are used in narrow spaces, it is the re-
sponsibility of each operator to ensure no one is in the danger area
of their own machine. The control will independently detect another
machine operating in its vicinity and adjust its frequency accordingly.
However,sinceitwillnotdetecttheneareldrangeofanother
control, the operator is required to pay attention to other machine
operators in the vicinity.
