Multi role armored vehicule

Qui sommes nous?

Directed by the Michael UNAC, UNAC SAS’ headquarters are in VERGEZE, between MONTPELLIER and NÎMES in Southern France.

Historic worldwide specialist for more than 40 years in conception and realisation of trenchers for the installation of underground networks, UNAC have taken their experience and applied it in manufacturing small and medium sized mobile hydrostatic power transmission vehicles in the road-rail, military, forestry and snow-removal fields.

Originally founded in 1943, UNAC is directed today by Michael Unac, a descendant from a long line of entrepreneurs. Michael Unac, took up the family torch with the same passion that the past 2 generations displayed; each one used their creativity, desire and work ethic from manufacturing agricultural trailers to designing specialized machines on the cutting-edge of technology to make UNAC an undeniable player in promising sectors such as integrated underground conduit installation systems or dual-purpose road-rail machines, as well as state-of-the-art military dozers.


o the contrary of capitalistic multinational companies, UNAC bases its development on the most fundamental of human values: creativity, user-friendliness, listening, expertise, feedback, and customer service.

Current manufacturing trends are pushing manufacturers to become assemblers. UNAC decided to preserve their extensive expertise that covers all stages of production, from boiler and sheet metal works to electricity, including machining of parts. A UNAC carrier is therefore a home-made solution, crafted with care, which only those who see the product created from start to finish can provide.

The company has internal values that are tried and true, which always enable them to meet their customers’ needs. The value of UNAC products is the result of capitalizing on expertise.

TNA - Air Dropable Bulldozer







The TNA is an air droppable (by parachute), super-compact machine on caterpillar tracks. It ensures the following missions

  • Preparation and improvement of airport platforms (levelling, snow-removal, deforestation, mulching, etc.) to allow air plane landing and take-off
  • The opening and basic landscaping of access routes
  • Removal of obstacles on the runway or approaches
  • Creation or restoration of lanes for recovering loads
  • Participation in basic protection of forces (slopes and shooting or surveillance locations).

The TNA is a compact 6.5 tonne bulldozer that can be equipped with a backhoe on the front and a ripper on the back.
The chassis is made of high elasticity steel. The chassis composition is completely optimised. The high-resistance aluminium alloy is used to obtain very high weight/resistance ratios. The chassis holds the caterpillar tracks, engine, tanks and cab.

The cab is made mobile by cylinders, which also enables it to be placed in an ultra-compact transport and parachute position. The cab is ROPS/FOPS certified. It is equipped with removable armour that meets the STANAG 4569 level 2 standard, as well as anti-mine armour standards.



  • Track drive transmission with one dedicated pump per track
  • Above average weight/power ratio with a 100 cv CATERPILLAR engine for 6.5t
  • Multi-purpose use with its multi-use blade (lifting, strip and overturning), ripper teeth and backhoe
  • Mobility with speeds up to 11 km/h
  • Its strategic transport capabilities on very short notice, due to its ability to be transported in various types of aeroplanes.
  • Its ability to be air-dropped from C130s, C160s and A4000Ms
  • Its ability to be transported on C130s, C160s and A4000Ms
  • Its ability to be transported on NATO heavy helicopters such as the CH47 or CH53
  • The cab that can be lowered to optimise its envelope when launched
  • Integration of high-tech materials that optimise its weight and offer extreme resistance of up to 50 Gs of force on landing.
  • Option of including a PR4G radio station
  • Includes a NATO intervehicle socket
  • Armour is removable to return to civil mode or for work in no-risk areas
  • Armour can be assembled/dismantled in only an hour
  • The carrier has an integrated armour storage compartment so that the machine can transport it independently.


Excavator rail/road 20TRR

The 20TRR is a high-capacity road-rail excavator that can perform earthwork tasks directly from a railroad track with great freedom of movement and with a large lifting capacity.


The 20TRR is a self-propelled vehicle with hydrostatic drive. This road-rail excavator is intended for any railway works. This vehicles is initially a Caterpillar excavator on which is maintened the same boom kinematics as the original machine and then modified in order to benefit from:

  • Setting up of clipped counterweight to lift huge loads
  • A sophisticated UNAC SMART-CS peripheral-view and operator indication system to receive real-time information regarding the machine, its load, and tilt, and to configure limits.
  • Two UNAC-HDTP motorized rail axles for hydrostatic driving and braking, without necessity of oscillating axle – Exclusive UNAC concept.


  • Very safe system, satisfying the most stringent road-rail standards, allowing to work under live wires
  • Real-time indication of track cant and load, without restraint on the machine
  • Very flexible axles that help to reduce risks of toppling and can tolerate high twists of tracks
  • Can work in both directions of the rail tracks thanks to the turret’s continual full rotation and the rear-view cameras
  • Electronic security system for the boom’s kinematics (different contact wire height levels) and for the rotation depending on a track’s status (cant and slope, adjacent track side, etc…)
  • Great acceleration and deceleration when on tracks to optimize time spent on work sites, even under rain situation thanks to the full hydrostatic system on the railway wheels (no contact with tires)
  • 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
  • The Caterpillar initial warranty is officially maintained. The excavator benefits from the UNAC after-sales service and from Caterpillar’s dynamic after-sales network.
  • Maintains the original excavator’s lifting and earthmoving workings capacities. The R/R excavator can lift 2T to a distance of up to 6m from the track centre, in an unfavourable cant situation and can therefore handle heavy equipment or also off-track works.
  • Possibility to make earthmoving and lifting from a track to the opposite side of the adjacent track
  • Equipped with a sophisticated system UNAC SMART-CS, which allows to work in safe and controlled space, and maximize the work space
  • Luxury/Comfort version cab of Caterpillar, getting an optimal ergonomic of the commands, and matching comfort, soundproofing, visibility and air conditionning.
