Why is Verdegro’s truck mounted attenuator called Armadillo?

Herman Harderwijk · 06 Oct 2026

We call our truck mounted attenuator the Armadillo because of the real animal it is named after: the armadillo, a creature covered in hard, protective scales that shield it from danger. Just as the animal uses its tough outer shell to absorb and deflect impact, our crash cushion is built to do exactly the same on the road. Below, we answer the most common questions about the Armadillo TMA so you can understand what makes it stand out.

What animal inspired the Armadillo name?

The Armadillo truck mounted attenuator takes its name from the armadillo, a small mammal known for its distinctive hard, scaled shell. The animal uses those rigid plates to protect itself against predators and physical threats. We designed our crash cushion with the same principle in mind: a strong structure capable of absorbing a powerful impact to protect the people behind it.

The name is not just a creative label. It reflects a deliberate engineering philosophy. Where a scorpion folds and recoils, the armadillo absorbs. That distinction captures exactly how our TMA behaves during a collision: rather than deflecting or redirecting energy unpredictably, the system is built to take the hit and manage that energy in a controlled, protective way.

This naming approach is consistent across our product range. Our VanGuard TMA, for instance, takes its name from the concept of a guard positioned in front of a van. Every product name at Verdegro is chosen to communicate function, not just identity.

How does the Armadillo TMA absorb crash impact?

The Armadillo TMA absorbs crash impact through a single aluminium crash cushion element that deploys in one continuous motion. When a vehicle strikes the attenuator, the cushion compresses and deforms in a controlled sequence, converting the kinetic energy of the collision into structural deformation rather than transferring it to the host truck or the workers ahead.

Several design choices reinforce this absorption capability:

Single-stage deployment: The system deploys in less than 20 seconds while driving at 80 km/h (50 mph). With no secondary extension stages, the cushion reaches its full operational position quickly and consistently, reducing the risk of partial deployment during an incident.
Mechanical simplicity: The Armadillo operates without sensors or electronic feedback systems. Fewer components mean fewer points of failure, and the system remains reliable in harsh, demanding environments.
Hydraulic ram positioning: The two hydraulic rams are positioned so that there are no oil leaks or environmental risks in the crash zone, which matters both for safety and for post-impact cleanup.
Integrated underride protection: Built directly into the steel framework, this feature prevents a striking vehicle from sliding underneath the attenuator, which is one of the most dangerous outcomes in rear-end collisions.

The aluminium crash cushion can be finished in any RAL colour, and the entire hydraulic and electronics unit is enclosed in a sealed protective housing, keeping the system operational across a wide range of weather and site conditions.

What safety standards does the Armadillo TMA meet?

The Armadillo TMA is fully crash tested and approved according to MASH 2016 TL-3, the most current standard in traffic safety testing. It holds acceptance for test levels 3-50, 3-51, 3-52, and 3-53, with optional test 3-54 also available. It is additionally approved according to the UK optional 110K test under TD49/07, making it compliant for deployment in both European and UK road environments.

Beyond crash testing, the Armadillo TMA carries CE marking and is EMC compliant. It is delivered with official crash test certifications, so you receive documented proof of compliance as part of the standard package. This matters when working with government agencies or contractors who require full certification records before approving equipment for use on public roads.

Verdegro holds multiple FHWA acceptance letters under MASH 16, which reflects our broader commitment to meeting the most rigorous international safety benchmarks across our entire product range, not just the Armadillo.

Where is the Armadillo TMA typically deployed?

The Armadillo truck mounted attenuator is typically deployed in active road maintenance and construction work zones, where it protects workers from rear-end vehicle intrusions. It mounts to a shadow vehicle that follows slowly behind road crews, acting as a mobile barrier between traffic and the work zone.

Its compact design makes it particularly well suited to a wide range of site conditions:

Narrow lanes and constrained work zones: With an overall width of 2300 mm (7.5 ft), the Armadillo fits in tight spaces without unnecessary overhang, and its design gives it the shortest possible turning circle in its class.
High-speed roads: Tested and approved at TL-3 impact speeds, the system is rated for use on motorways and dual carriageways where traffic moves at higher speeds.
Flatbed truck operations: The upright transport position (3940 mm / 12.9 ft) preserves full access to the truck’s flatbed. Operators retain complete use of the flatbed for carrying tools, materials, or other equipment while the TMA is in transport mode.

The system is compatible with trucks weighing between 7,228 kg and 12,475 kg, which covers a broad range of standard support vehicles used in road maintenance fleets. The maximum roll-ahead distance after impact is 7250 mm (23.8 ft), a figure that reflects the system’s controlled energy management during a collision.

How does the Armadillo compare to other Verdegro safety products?

The Armadillo is our truck mounted attenuator for standard support trucks, while our other crash products serve different vehicle types and operational contexts. The clearest comparison is with the VanGuard, which is the world’s first TMA designed specifically for closed vans. Together, they cover the two most common shadow vehicle types used in road maintenance.

Here is a side-by-side overview of the key differences:

Vehicle type: The Armadillo mounts on trucks (7,228 to 12,475 kg). The VanGuard is designed for closed vans such as Renault, Mercedes, Iveco, and Opel models.
Mounting options: The Armadillo uses a single rear-mounted configuration with optional accessories including multi-truck brackets and arrow board brackets. The VanGuard is available in three variants: rear mounted, top mounted, and swing mounted.
Deployment mechanism: The Armadillo deploys in a single continuous motion in under 20 seconds. The VanGuard rear-mounted version unfolds into a 90-degree operational position; the top-mounted version slides down vertically.
Flatbed access: The Armadillo’s upright transport position preserves full flatbed access. The VanGuard’s top- and swing-mounted versions keep the van’s rear doors fully usable.

Both products share our core design values: mechanical reliability, certified crash performance, and practical usability in real working conditions. Both are also compatible with Mobitrack, our integrated tracking module that provides real-time GPS location data, location history, and integration with safety alert platforms including Google, Waze, and Flitsmeister. This means you can monitor your attenuators alongside the rest of your fleet through a single system.

How Verdegro Supports Your Work Zone Safety Setup

We design and manufacture the Armadillo TMA to meet the specific demands of road crews, highway contractors, and municipal transport departments that need dependable protection in active work zones. Here is what we offer alongside the attenuator itself:

Full certification package: Every Armadillo TMA is delivered with official crash test certifications, CE marking, and EMC compliance documentation, so your procurement and compliance teams have everything they need from day one.
Flexible accessories: Quick-connect systems allow you to swap the attenuator and arrow board by forklift. Optional accessories include MASH-approved multi-truck brackets, arrow board brackets, jockey wheels, and reflective foil chevrons to country specification.
Mobitrack integration: Add real-time GPS tracking, location history, and safety alert integration to your Armadillo TMA. Mobitrack connects automatically with Google, Waze, Flitsmeister, Monotch, and national traffic control systems, sending alerts to drivers approaching your work zone.
Broader product range: If your fleet includes vans as well as trucks, our crash safety systems cover both vehicle types, giving you a consistent safety standard across your entire operation.
