NevaFail™ is an LED asset ID panel for haul trucks, water carts and mobile plant, made by National Plastics & Rubber (NPR) in Brisbane, Australia. It pairs high-brightness LEDs with an ASTM D4956 fail-safe reflective backing, so the fleet number stays readable by day, at night and even when power drops. It is IP68 rated, runs on 24 V and is distributed in Peru by Endeavant S.A.C.
Why do fleet numbers on mining equipment become unreadable?
Painted and decal fleet numbers break down under dust, high-altitude sun, vibration and abrasive material. At night they are only readable if another light source hits them: a truck's headlights light the road, not its own number. When numbers can't be read, dispatch slows down, intersection traffic control loses accuracy and incident reconstruction gets harder. For the wider picture, read our guide to mining vehicle identification and signage.
How does a NevaFail™ panel work?
A NevaFail™ LED ID panel has two layers of visibility. The first is the high-brightness LED, which emits its own light. The second is a fail-safe retroreflective backing certified to ASTM D4956, the same standard used for road signs: if power is lost, the number still reads under headlights. That is what NPR means by "fail-safe".
The body is a single piece moulded in 95A polyurethane that resists corrosion, impact and vibration. Panels are IP68 rated against water, dust and oil, and the whole range runs on 24 V, the standard electrical system on mining machinery. NevaFail™ is patent pending in Australia (application no. 2019903240), meets the BMA identification specification and has been in Australian mines since 2019.
What digit height does each machine need?
NevaFail™ digit height is chosen by machine size and reading distance. NPR makes three heights: 300 mm for mobile plant under 120 t, 400 mm for machines of 120 t and over, and 600 mm for the front of water carts and haul trucks.
| Digit | Application | Format | Part no. |
|---|---|---|---|
| 300 mm | Mobile plant under 120 t | Flat, triangle or square | NPR06709-00 · NPR07481-00 · NPR08665-00 |
| 400 mm | Mobile plant 120 t and over | Flat or triangle | NPR08249-00 · NPR08771-100 |
| 600 mm | Front of water carts and haul trucks | Flat | NPR08564-00 · NPR08673-00 |
Flat, triangle or square panel?
NevaFail™ comes in three formats, all 24 V, and every combination of format, mounting, configuration and digit height has its own part number:
- Flat: mounts straight onto a surface of the machine. 300, 400 and 600 mm digits, 13 to 43 kg depending on the model. It is the only format offered with 600 mm digits.
- Triangle: reads from more than one angle. Bolt-on or magnetic base at 300 mm, bolt-on at 400 mm; 27 to 66 kg.
- Square: the newest format in the range: NPR08665-00, 300 mm, 3 numbers, bolt-on, 39 kg.
A handrail bracket, NPR08659-00, is available for models NPR06709-00, NPR07147-00, NPR08249-00 and NPR08673-00.
Can you change the number on a NevaFail™ panel?
Yes. On interchangeable models the number is changed on site without replacing the panel. NPR offers three ways to set a machine's ID:
- Interchangeable: 1 to 3 digits swapped using the supplied blanks, behind a polycarbonate front panel. Available in every size, and useful when a machine is reassigned or the site renumbers its fleet.
- Custom: fixed letters and numbers for sequences of 4 or more characters, water-jet cut from black polyurethane for permanent ID.
- Hybrid: fixed letters plus an interchangeable number, for fleets that use an area or equipment-type prefix. For example NPR08564-00 (2 fixed letters + 2 numbers) and NPR08673-00 (2 fixed letters + 3 numbers), both with 600 mm digits.
How does NevaFail™ compare with painted numbers and reflective decals?
The difference between NevaFail™ and traditional fleet numbering comes down to what the number depends on to be read in each condition:
| Condition | Paint or decal | NevaFail™ |
|---|---|---|
| Daytime | Readable while the surface is clean and intact | High-brightness LED plus reflective backing |
| Night | Needs another light to hit it | Emits its own light |
| Power loss | Not applicable | ASTM D4956 reflective backing keeps it readable |
| Renumbering | Repaint or make a new sign | Swap blanks on site (interchangeable models) |
| Environment | Wears with dust, sun and abrasion | IP68 against water, dust and oil; 95A polyurethane |
How does NevaFail™ help mine traffic and dispatch?
NevaFail™ gives operators, dispatch and supervisors the same visible reference for every machine. NPR calls it positive two-way communication: numbers are recognised from a distance, dispatch moves faster and radio mix-ups drop. The panel supports the visual equipment ID rules required on mine sites (BMA specification) and works as a visual check that does not depend on the GPS dispatch system.
Identification is one layer of traffic management. For the risk of people near moving plant, the Safety Halo™ laser exclusion zone projects onto the ground the perimeter nobody should cross. Every NPR product we distribute is in the NPR catalogue.
Where can you buy NevaFail™ in Peru?
Endeavant S.A.C., based in Miraflores, Lima, distributes National Plastics & Rubber products in Peru, including the full NevaFail™ range. We help you pick format, mounting, digit height and numbering for your machines. If your workshop also needs cribbing, see Stacko™ cribbing blocks.
NevaFail™ FAQ
Does NevaFail™ stay readable if power is lost?
Yes. On top of the high-brightness LED, every NevaFail™ panel has a fail-safe retroreflective backing certified to ASTM D4956, the road-sign standard. If power is interrupted, the fleet number remains readable under headlights.
What NevaFail™ digit height do I need?
NPR recommends 300 mm digits for mobile plant under 120 t, 400 mm for machines of 120 t and over, and 600 mm for the front of water carts and haul trucks. The 600 mm digit is only available in the flat format.
Can the number on a NevaFail™ panel be changed?
Yes, on interchangeable models: 1 to 3 digits are swapped on site with the supplied blanks, without replacing the panel. For 4 or more characters or fixed letter-and-number combinations, the custom model is water-jet cut from black polyurethane.
What voltage does NevaFail™ run on and how is it mounted?
The whole NevaFail™ range runs on 24 V, the standard electrical system on mining machinery. Depending on the model it is bolted on or uses a magnetic base, and a handrail bracket (NPR08659-00) fits the compatible flat models.
Who distributes NevaFail™ in Peru?
Endeavant S.A.C., in Lima, distributes National Plastics & Rubber (Brisbane, Australia) products in Peru, including NevaFail™ flat, triangle and square panels, and helps you choose format, mounting and fleet numbering.
