2Introduction:
A Truck Mounted Attenuator (TMA) is an energy absorbing device attached to the rear of a truck or
utility vehicle. A TMA is designed to provide a controlled stop of a vehicle impacting the rear of the
truck. TMAs have been used since the mid- 1970's to reduce the severity of impacts between errant
motorists and slow moving or stopped shadow vehicles used to protect highway maintenance
workers.
The National Cooperative Highway Research Program Report 350 (NCHRP 350) specifically addresses
the performance requirements of TMAs. The recommended tests to evaluate TMA crash
performance are defined for two different Test Levels. The basic Test Level, TL-2, is conducted at a
nominal impact speed of 70 kph. TL-3 is the higher test level and is conducted at 100 kph.
This report presents the manual for the Verdegro TMA, type US at the more demanding NCHRP 350
TL-3 test conditions.
The Verdegro TMA-US 100K, in this manual called TMA is a device with an optional framework for a
sign, eventually with LED arrow or LED display. The TMA is fully hydraulic operated and must be
placed behind a supporting truck with a minimum weight of 8.000 Kg and a maximum weight of
12.000kg12 for best performance results. The crash cushion mounted on this TMA is 100K, which
means test with the TMA were done according TL-3 of the Report NCHRP-350.
The TMA is amply equipped with features that promote safety. By inspect them, the quality,
efficiency and safety of the TMA improved.
Check the condition of the TMA daily before starting work on the base of the instructions. It is strictly
forbidden to use the TMA when it is damaged, not maintained or inspected.
The Manufacturer reserves the right to the machine construction, parts and maintenance
instructions without notice.
This manual is only for the Verdegro TMA-US-100K. Some drawings or colors in this manual
can be slightly different from the delivered model which should be recognized as a typical
Verdegro TMA-US 100K.
Attention! Before maintenance or checks, disconnected the power!
1For some countries other specifications are mandatory. See chapter “supporting vehicle” for specifications.
2If you have a truck which is heavier, contact Verdegro or your distributor.

5General specifications and instructions
A. Always make sure the system is delivered with the right certificates, stickers and
documentation!. Do not remove the sticker(s)!!
B. Make sure the validation time of the certificates is never exceeded!
C. Never remove safety instructions of the TMA!
D. All Verdegro Truck Mounted Attenuators (Verdegro TMA) shall be designed and
manufactured by the Verdegro Group, in accordance with the specifications.
E. The Verdegro TMA is an attenuator system designed for installation at the back of trucks
with gross vehicle weight (GVW) ranges between 8000 kg and 12 000 kg3(Contact your
country for other specifications!).
Note: Any added ballast must be adequately anchored to the truck so that it will not move
during impacts. Because the back end of the truck supports the weight of the rearward
protruding TMA, care must be taken not to exceed the manufacturer's published maximum
axle loads. To ensure that the driving characteristics of the vehicle are maintained, the
manufacturer's recommended center-of-gravity zone should also be adhered to.
F. A truck equipped with a Verdegro TMA shall have a forward skid distance of less than 10 m
during an impact by either an 820 kg or 2000 kg vehicle traveling at a design speed of 100
kph. The minimum forward skid distance is dependent on the truck’s transmission being in
second gear, and the parking brake set with the truck situated on clean, dry pavement.
5.1.1 Description of system
A. The Verdegro TMA shall consist of the following basic components: An aluminum foldex box
with 4 aluminum Cartridges, a steel Support Structure and a Support Frame with 2 mounting
options for attaching the system to the truck.
A hydraulic system shall also be included in the system to raise the structure and cartridges
to a vertical position. When the system is in a horizontal position, the frame assembly shall
be capable of collapsing when impacted by an errant vehicle. No portion of the system shall
protrude forward under the truck during an impact. The total mass of the system shall be
approximately 980 kg. The complete Verdegro TMA is designed to make attachment or
detachment from the truck simple and fast.
B. The Verdegro TMA shall have a standard trailer lighting system. This system shall include
brake lights, taillights and turn signals. The wiring for the rear lights shall be routed and
secured on the articulating frame. This system also has additional lights on the cartridge so
that the lighting system meets the standards, whether the system is in its horizontal or
vertical orientation.
C. Under the support frame are two tubes to lift the complete system with a forklift, for
example to mount on the truck.
3If you have a truck which is heavier, contact Verdegro or your distributor.
