1.2 Machine Description
The trench compactors of the TRC 66 and TRC 86 series are used for the compaction of cohesive and heavy
cohesive soils being excavated on site and used again as backfill material.
Propulsion
The propulsion unit, a water-cooled Lombardini diesel engine, type LDW 1003, drives three gear pumps,
whereby one pump acts on the L.H. drums and the other on the R. H. drums. The third gear pump is provided
for the vibration drive. The hydraulic functions are controlled by means of a hydraulic control block, electric
switches and electric valves. Vibration is automatically or manually actuated by means of a direction
commutator. The hydraulic system also includes an hydraulic oil tank, an oil /water cooler, valves and tubes.
The multiple disc brake acts on the two rear drums. The engine is started via the ignition lock or the remote
control unit. The engine speed (idling/full speed) is adjusted by means of the adjusting knob. The hourmeter
indicates the operating hours of the compactor. The scrapers are provided to prevent soil from sticking to the
drums.
Electrics
The three-phase alternator supplies the voltage for the 12 V electrical system and the battery. The alternator
charge warning light warns when the battery voltage is too low.
Operation
The TRC 66 andTRC 86 compactors are either operated by hand or by radio remote control.
Brake system
When the compactor is put out of operation, the multiple disc brake is automatically applied and acts as a parking
brake. As soon as the diesel engine starts, the brake is hydraulically released.
During operation, the hydrostatic drive acts as a service brake.
Remote control
The remote control unit consists of a sender, a receiver and a charger. The sender and the receiver are
programmed with addresses stored in the internal micro controller. Since each of these addresses is unique,
misorders from other units operating on the same frequency are avoided (radio signals from other units are not
accepted by the receiver). Two light-emitting diodes in the sender flash to indicate a correct order transmission
(green LED flashes) and monitor the accumulator charge (red LED flashes in case of undervoltage).
