TNA

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).

Description

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.


Strengths

  • 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.
