Purpose
The UNAC 8TRR mini-excavator can carry out
lifting and earthwork operations on roads as
well as on HST tracks, conventional tracks, and
tram networks.
Description
The UNAC 8TRR is a self-propelled hy-rail
mini-excavator with hydrostatic transmission.
The 8TRR was inspired by a basic Caterpillar
mini-excavator for which the boom kinematics
were completely maintained, apart from railroad limitations.
On the road, the mini-excavator has the same
characteristics as a standard mini-excavator,
except its stabilisation and backlling blade
is retractable thanks to a quick mechanical
attachment system. On rail-roads, the 8TRR
moves at speeds of up to 20 km/h thanks to its
rail-road lorries.
The UNAC 8TRR mini-excavator has the
following features:
• A comfortable, hermetic, heated and airconditioned cab.
• A caterpillar frame with rubber tracks that
are controlled independently by levers
inside the cab.
• A single-block boom with boom leg rotation. The boom’s height is limited when
working under high-voltage wires.
• Two UNAC-HDX type lorries with a lifting
system.
• A turret rotation movement that can be restricted at two places in order to secure trafc on an adjacent lane.
• A sophisticated UNAC-SMARTCS that
includes a rear-view camera and operator indication system to receive
real-time information concerning the
machine, its load, and tilt, and to congure
limits.
Strenghts
• Secured by electronic management for
the boom kinematics (different catenaries’
heights) and for the rotation according to
the work situations, backed up by mechanical safeties.
• Ergonomic controls in a premium Caterpillar
cab that combines comfort, soundproong,
air conditioning, visibility.
• Robust, reliable and easy maintenance.
• Can work in either lane direction thanks to
the turret’s full rotation and rear-view camera.
• Caterpillar warranty ofcially maintained
The excavator benets from the UNAC
after-sales service and from Caterpillar’s
dynamic after-sales network.
• Maintains the original excavator’s lifting
and earthwork capacities. The Rail/Road
excavator can lift over 1 T up to 2.5 m from
the centre of the track. The mini-excavator
can thus lift very large loads in comparison
to its size.
• Very safe system, satisfying the most stringent rail-road standards, authorising work
under live powerlines and leaving adjacent
lanes open for incoming trafc.
• Electric emergency pump included,
allowing signicant autonomy in electric mode at about 80% lifting capacity
and 20% kinematics.
• Machine certied for circulation on the
French network.
• Caterpillar frame for easy manoeuvring with zero turning radius,
making getting onto rails easy
• Angle of attack for all-terrain
transfer greater than 50°.
• Very stable thanks to its very low centre of
gravity.
• Possibility of using the blade by installing
it via the quick mechanical attachment
directly on the lorry.
• Boom kinematics providing great liberty
with the possibility of making trenches
parallel to the rail-road using the boom leg
rotation.
• Great digging depth, even from the railroad track.
• Wide range of usable tools: auger, hydraulic rock breaker, buckets, hammers, universal pliers, hydraulic shears, mechanical
pliers, compactor, clips with claws, loading
bin, earthwork bin, and stripping beam.
• Signicant digging depth.
• Automatic selection of lorries while lifting or
getting on rails.
• Ultra-short rear radius to work in smaller
zones such as tunnels.
• Signicant rate of speed when on tracks.
• Great acceleration and deceleration when
on tracks to optimise time spent on work sites
• Indication of lane inclination and load in
real time.
