Armtrac 20T Robot - Unmanned Ground Vehicle

Clearance Of Explosive Ordnance
The Armtrac 20T Mk2 Robot is a flexible, cost effective, remote controlled Small (Heavy) Unmanned Ground Vehicle (UGV).  It can be fitted with a variety of toolkits including a demining flail, tiller and rear excavator equipped with different attachments.  In C-IED operations, a detector system can be mounted on the front and an IED disruptor can be fitted on the rear arm. It has a 74 HP diesel water cooled Kohler engine which can operate for several hours continuously without refuelling. All hydraulic hoses and couplings are internationally common.

The Armtrac 20T Robot is capable of performing the following roles:

Conventional Demining & EO Clearance Operations

  • Technical Survey and EO Reconnaissance
  • Mechanical clearance where there is restricted access for larger mechanical equipment
  • Vegetation cutting prior to manual or canine assisted demining
  • Small clearance operations & area reduction
Counter-IED Operations

  • Support to C-IED operations
  • Support to Route Clearance operations
  • Surface/Sub-surface IED Disposal
  • Mechanical Surrogate Scout for Dismounted Foot Patrols

The Armtrac 20T Mk2 has heavy duty rubber tracks producing a ground bearing pressure of less than 5 PSI but can be fitted with wider tracks for softer terrain.  It is very employable in challenging terrain where larger machines cannot access because it is small, manoeuvrable and can climb, descend and traverse 45° slopes & deep gullies due to its low centre of gravity & power. The UGV itself weighs 1840 Kg.

The Armtrac 20T is operated using a control station. The control station transmits operator demands to the UGV and facilitates operation of the UGV by displaying key vehicle data.  The Robot can be fitted with video feedback from up to four on board cameras; one camera is situated forward and a second situated at the rear.  The other two are mounted on the Rear Excavator and Manipulator Arm to aid detailed remote investigation.   When cameras are fitted, the LED display unit can be situated on the control unit, in a peli-case or mounted on a tripod which is supplied.
The Tiller tool spins at 600 - 800 RPM and has a clearance width of 1515mm (Flail 1476mm).  It is attached using a quick hitch coupling. It clears Explosive Ordnance (EO), including anti-personnel mines and Improvised Explosive Devices (IED) by detonation or by shattering the EO so it cannot function.  The tiller can achieve clearance depths down to 150 mm depth or 200 mm in softer soil & has been tested against 2 Kg of explosives (left).  This demining tool is also an efficient vegetation cutter up to 35 mm diameter when used in conjunction with manual or canine search and clearance techniques.
The hydraulic Backhoe Excavator can be fitted onto the rear of the Armtrac 20T using a quick hitch system. The backhoe can attach a Grapple or a Manipulator Grab for investigating suspect EO or moving EO to a safer location for further investigation or render safe procedures. Alternatively, the excavator can operate a standard Scrape Bucket for exposing buried EO/IEDs or constructing trenches to mitigate the effects of EO and a vegetation cutting strimmer.  The Manipulator Grab, Grapple, Scrape Bucket and the Strimmer can all be exchanged rapidly using standard tools.
A20T Mk2 investigating suspect device with grapple
A Disruptor or Exploder for disposing of surface IEDs can be fitted to the Excavator to give additional capability. To complement this and other requirements, the close up camera system fitted on the Excavator provides a live video link to the operator.  The Armtrac 20T is sufficiently robust and agile enough to move across country and provide a surrogate scout for dismounted foot patrols; in this role it would enhance situational awareness and stand-off detection of threats.  However, in mechanised operations, it could equally be transported on a standard 3.5 ton trailer and be prepared for operations within minutes of identifying a potential threat for survey, investigation or render safe.

The Armtrac 20T is inherently flexible and can clear UXO from hard surfaces and runways.   However it is also a powerful workhorse for light engineering tasks and when a forward mounted bucket (and/or forklift tines) are attached, it can undertake small construction tasks and remove loads or supect devices up to 1300 Kg.

The Rotary Mine Comb can extract anti-tank & anti-personnel mines from 20 cm depth without creating dust and with better fuel consumption.  It removes mines outside the Robot path for collection and disposal later without incurring any damage to the mines.  This is an excellent demining tool when dust needs to be kept to a minimum.

Armtrac 75t-230

Armtrac 75t-230

Armtrac 75T-230
The Armtrac 75T-230 is Armtrac’s middle of the range demining machine. Smaller than the Armtrac 400, the 75T still maintains all of the functionality of its bigger brother for all demining activities.

With its hydraulically operated 2.2 meter Tiller Rotor, the 75T is capable of clearing approximately 1,100 square meters per hour, to a verified (*CROMAC tested) depth of 35cm. A Flail is also available.

The 75T is designed to destroy & withstand 10kg Anti-Tank mines.

The 75T is fully remote controlled up to 800 meters allowing the Operator to remain at a safe distance while still maintaining 100% control of all the machine’s functions, or alternatively if fitted with its fully armoured, sound proofed & air-conditioned cabin (which can withstand NATO Ball at point blank range), an Operator can maintain a detailed “bird’s eye” view of demining operations in complete comfort & safety.

The cabin maintains the same design as the Armtrac 400; however it can tilt forward to allow easy access to the engine, hydraulics & electrics for ease of maintenance.

Armtrac 75T-230

Armtrac 75T-230

The Armtrac 75T-230 has a telescopic boom to which different clearance toolkits can be attached. This boom can be extended to clear mines and UXO in difficult locations such as on river banks and on inclines, while remaining completely stationary.  This is a unique feature to Armtrac tracked machines.

A variety of toolkits are available for clearing landmines and UXO. As well as a tiller and flail, the Armtrac Mine Comb can extract buried mines and UXO down to 50 cms.  When the Armtrac Sifter is fitted to the rear of the machine, this extracts items & potentially missed ordnance to 50 cms which provides a comprehensive quality assurance tool when used together with a front mounted tiller or flail.

By utilising industry standard quick hitch systems, numerous construction tool attachments can be exchanged for the demining toolkits.  The backhoe can be fitted onto the boom arm which provides a very versatile and far reaching tool with a standard scrape bucket or a grapple attached for extracting UXO which are difficult to access.

Armtrac 75T-230
Armtrac 75T-230
The quick hitch system will accommodate any standard construction tool such as buckets, dozer blades, fork lift tines or power grab, making the Armtrac 75T-230 an extremely versatile & useful machine in and out of high threat areas.   The boom arm will lift up to 2.7 tons which makes the Armtrac 75T a powerful workhorse for a wide range of levelling, loading, lifting and construction roles as well as clearing mines, IEDs and UXO. This gives it a “second life” after its clearance role.

The Armtrac 75T-230 is a versatile and flexible multi-role machine.  Maintenance is reduced to a minimum with its more reliable hydraulically operated tools but nevertheless, components are available worldwide from JCB.  These features, plus the innovative telescopic boom arm make this and our other Armtrac products strong market competitors.

Armtrac 100-350

Armtrac 100-350

The Armtrac 100-350 Mk2 is a cost effective, heavily modified & armoured multi-purpose machine & is built around the tried & tested JCB Fastrac 8000 tractor. As such, many of the components and spare parts are obtainable worldwide. 

The Armtrac 100-350 Mk2 features the same 3m Tiller and Flail Header as the Armtrac 400, driven from the PTO shaft at the rear of the tractor. All key components are fully armour protected & shielded. The Tiller and Flail is capable of cutting thick vegetation while simultaneously processing ground to a depth of 40cm.

There are many different demining, EOD and engineering toolkits that can be employed with the Armtrac 100 – 350 Mk2 as well as tillers and flails.  When the Armtrac Sifter or Minecomb is fitted to the rear of the machine, these can extracts item of potentially missed ordnance to 50 cms which provides a comprehensive quality assurance tool when used together with a front mounted tiller or flail. Also buckets, strimmers and backhoe excavators can be employed with this machine.

This tractor is licenced to drive on the road and can be driven to its destination at up to 70 KPH without the need for special trailer lift requirements.  As it is based on a commercial tractor it can be used in the agricultural or construction industry as well as in de-mining.  This gives the Armtrac 100 – 350 Mk2 a “second life” beyond its demining role both in and out of the high threat areas.

The Armtrac 100-350 Mk2 cabin is quiet, air-conditioned & features a fully adjustable air-sprung seat with a 4-point safety harness, adding to its comfort & safety.  There is an additional pilot seat in the cabin for an operator to operate additional remote equipment concurrently with the Armtrac 100 – 350 Mk2.  A special feature of this demining machine is its ability to operate toolkits on the front and the rear; the operator’s seat can swivel through 180 degrees so that the operator can always face the direction of travel using the respective toolkit on the front or rear of the machine.

The Armtrac 100 – 350 Mk2 is versatile enough and licensed to tow a trailer loaded with a portacabin and toolkits on commercial tarmac roads.  The trailer has foam filled tyres (optional, dependent on the threat), a 5 KVA generator and is lowed hydraulically to the ground to allow unloading.  The air conditioned portacabin could also house Personal Protection Equipment, Detectors and potentially an Armtrac 20T Robot ideal for Technical Survey and vegetation cutting.

The Armtrac C-IED Mine Roller System is designed to protect vehicles from the effects of victim operated devices and provides a level of confidence when proving routes for the presence of mines and IEDs. It can be used at lower speed with tracked Armtrac vehicles but another self-weight version of the Roller System can also be used with APCs or MBTs.

It is intended for use when there is a possibility, rather than a probability, of a victim operated device on an intended route. This is a full width proving device using two wheel banks each comprising of 7 rollers.  Each roller wheel is made from a polyurethane composite and is puncture proof.  The steering system can articulate the Armtrac Roller left or right allowing the system to negotiate moderate corners while still protecting the full width of the prime mover; its linkage arrangement allows each roller wheel to articulate over undulating terrain.  Left and right roller banks (of 7 rollers) are identical and interchangeable; they swivel a complete 360 degrees when reversing without interfering with each other. In the event of a significant explosive event, the complete roller bank sheers off the main frame at the weakest point and can be easily replaced by another roller bank.  Smaller explosions will only damage a roller which can be replaced.

When used with the Armtrac 100-350 Mk2, hydraulic power from the host vehicle is used to transfer up to 2000 Kg of additional weight transfer onto the roller wheels in order to generate sufficient force to trigger the pressure operated devices present.   When not route proving, the rollers can be lifted off the ground to provide greater speed and flexibility.  If the Roller System activates any explosive devices, the Armtrac 100 can operate a clearance toolkit such as a tiller or flail mounted on the rear of the machine and the operator’s seat can be reversed to facilitate the operation.

Armtrac Sifter

Sifter-3-13993Armtrac Sifter

The Armtrac Sifter is designed to provide a new level of quality assurance in mine clearing confidence.

It is intended for towing behind the Armtrac 400, 100-350 and the Armtrac 75T-230, lifting the tilled soil from a depth of 750mm.

12 rows of stars turn in a spiral configuration rolling and sifting the soil up towards the top of the star bed where the mines, UXO and any debris can be collected or dropped onto the ground for inspection.

There are no dead spots as the total area of the star bed is utilised to achieve maximum and uniform sieving of the soil. Hydraulically driven, PTO speed adjustment is provided to control star speed and a choice of spacing to facilitate the most effective soil and stone separation.

Once reaching the top of the star bed the Over Band Magnets remove and separate ferrous metals, ready for collection in the holding bucket, leaving the land clear of UXO and metal fragments.

A Magnetic Head Roller is fitted underneath the star rollers to pick up ferrous metal that may drop through providing a double collection and assurance.

The Armtrac Sifter is provided with steel braced wheels and tyres and on ground tilled by either the Armtrac 400 or the Armtrac 75T-230, can process up to 5000 square metres per hour.

Armtrac Mine Comb

Minecomb-#1-90761Armtrac Mine Comb

Due to its digging action, the Armtrac Rotary Mine Comb is a unique and innovative method of Anti-Tank mine extraction. It gently lifts buried objects from the soil and pushes them to the side of the vehicles path, where they may be collected and contained or detonated safely.

The Armtrac 20 Robot is the perfect tool for the collection of extracted mines. Two ground engaging rotors each contain four tines which intermesh and counter rotate as the vehicle travels forward. These tines lift and continuously nudge large objects the size of anti-tank mines to the outside edge of the vehicle with little soil movement or creation of unwanted berms.

Because of this method the Armtrac Rotary Mine Comb can operate continuously for many hours and remains relatively unobtrusive of the environment.

The Rotary Mine Comb can be used with a number of different vehicles. It has been integrated onto a small armoured construction style crawler dozer as well as commercial tractors and is designed to fit all Armtrac vehicles. A new hydraulic system is now being manufactured to suite all Armtrac’s 400, 100-350 and 75T-230 vehicles.

The Rotary Mine Comb is currently being operated in Angola, progressing nearly one kilometre per day clearing roads of undetectable AT mines.

Strimmer

strimmer01

Strimmer

The Armtrac Strimmer is designed as an aid in ground UXO clearance, specifically for difficult to reach areas where none of Armtrac’s other machines are able to reach. As with all Armtrac products, the Armtrac Strimmer is armoured to withstand Anti-tank mines.

The Strimmers single flail header can operate horizontally with an effective 2 meter diameter clearance area, or it can be tilted vertically to apply a direct impact on any difficult or suspicious objects. In the vertical plain the Strimmers 3000RPM flail has an impact force of 80 Tonnes/ square inch, totally destroying anything in its path.

The Armtrac Strimmer uses the same industry standard fittings allowing it to be attached to any variety of appropriate machines including the Armtrac 75T-230 and Armtrac 400. The Strimmer uses the hydraulic connections from the host vehicle, therefore no additional power pack is necessary.

It is most suited for fitment to a long reach excavator, to enable it to reach into difficult areas and slope angles. The digger blade doubles as a protection shield from the flail and debris, as well as to claw and dig rocks and moving banks for the machine to move freely and safely between areas.

Armtrac Roller

Armtrac Roller

The Armtrac Roller System is designed to protect vehicles from the effects of victim operated devices and provides a level of confidence when proving routes for the presence of mines and IEDs. It can be used at up to 50 KPH when fitted to the Armtrac 100 and at lower speed with tracked Armtrac vehicles but another self-weight version of the Roller System can also be used with APCs or MBTs.
