2Introduction:
A Trailer truck mounted attenuator (TTMA) is an energy absorbing device attached to the rear of a
truck or utility vehicle. A TTMA is designed to provide a controlled stop of a vehicle impacting the
rear of the truck. TTMAs 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 TTMAs. The recommended tests to evaluate TTMA 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 TTMA, at the more demanding NCHRP 350 TL-3
test conditions.
The Verdegro TTMA 100K, in this manual called TTMA is a device with an optional framework for a
sign, eventually with LED arrow or LED display. The TTMA 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 TTMA is 100K, which means test with the TTMA were
done according TL-3 of the Report NCHRP-350.
The TTMA is amply equipped with features that promote safety. By inspect them, the quality,
efficiency and safety of the TTMA improved.
Check the condition of the TTMA daily before starting work on the base of the instructions. It is
strictly forbidden to use the TTMA 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 TTMA-100K. Some drawings or colors in this manual can be
slightly different from the delivered model which should be recognized as a typical Verdegro TTMA -
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 TTMA!
D. All Verdegro Trailer truck mounted attenuators (Verdegro TTMA) shall be designed and
manufactured by the Verdegro Group, in accordance with the specifications.
E. The Verdegro TTMA 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 TTMA, 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 TTMA 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 Performance criteria
A. The Verdegro TTMA, when mounted to a truck weighing up to 9,000 kg situated on clean dry
pavement with the transmission in second gear and the brakes locked shall perform as
follows:
1) Vehicles with a mass of 820 kg impacting straight into the rear of the TTMA at 100 kph
shall remain upright with the theoretical occupant impact velocity of 12 m/s or less and
the occupant ride down acceleration of 20 g's or less per NCHRP 350, Test 3-50
evaluation criteria. The truck shall be placed against a non-moving wall, also called a rigid
barrier, during this test.
2) Vehicles with a mass of 2000 kg impacting straight into the rear of the TTMA at 100 kph
shall remain upright with the theoretical occupant impact velocity of 12 m/s or less, and
the occupant ride down acceleration of 20 g's or less per NCHRP 350, Test 3-51
evaluation criteria.
3) Vehicles with a mass of 2000 kg impacting straight into the rear of the TTMA at 100 kph,
and an offset of W/3 with respect to the TTMA centerline, shall remain upright with no
significant roll pitch or yaw per NCHRP 350 optional Test 3-52 evaluation criteria.
4) To minimize potential damage to the truck, no portion of the TTMA’s structure or energy
absorbing elements shall protrude forward of the underride during an impact. Certified
test results and associated test reports and films produced in the guideline with NCHRP
350 procedures shall be submitted showing that the TTMA system conforms with all test
and performance criteria in this specification.
B. The Verdegro TTMA cartridges shall successfully perform to accelerated vibration, moisture
and corrosion.
3If you have a truck which is heavier, contact Verdegro or your distributor.

6Safety
1. Read these instructions carefully before using the “TTMA”
2. The TTMA should not be used without knowledge of the operating instructions and safety
precautions. Keep the operating instructions, always within easy reach of the machine, the
operator's manual should ALWAYS be at or near the machine.
3. The operator of the TTMA must be at least 18 years old and experienced in serving Trailer
truck mounted attenuators.
4. The owner/holder of the TTMA must ensure that all users are trained in the use of the
machine.
5. Be careful when the machine is used near live power lines.
6. Transport the TTMA only if it is properly secured to vehicle.
7. On the platform are no persons during storage and adjustment of the machine or in transit.
8. Make use at all times during the adverse influences of wind, rain, temperature, brine,
thunderstorms, snow, hail and ice.
9. Use the TTMA purely as Trailer truck mounted attenuator, and not as a transport trailer or
other device.
10. The wind load of the TTMA does not increase with additional signs or other objects that
could catch wind.
11. Inspect the entire machine for loose materials such as bird nests, twigs, leaves, but also
tools, bolts, nuts, etc. which may end up on the lanes during mobilization or transport.
12. Do not hoist the TTMA!
13. Before and during operation of the machine always look at / near the machine, no persons
are present, guiding also takes into account the rotation range of the machine!
14. For safe and trouble-free operation, the TTMA clean snow and ice held.
15. The TTMA regular inspection and maintenance of service - repair outsourcing to an expert in
this field service company.
16. The construction of the TTMA may not be altered without permission and the
manufacturer's instructions.
17. Inspect the TTMA every day before work or during use and pass through the machine.
18. Axles control all bolts / nuts: Before each use the principal axes, bolts and nuts.
19. Let the TTMA annual inspect by the manufacturer. The inspection must take place more
frequently if welding is done in supporting parts, or other special reasons exist for the device

to be debating. For modification and repair, always contact the manufacturer!. After repair
or replacement of parts, the TTMA should always be served a full test facility. The Verdegro
Group can only guarantee the working when repair and service is done by the Verdegro
Group or under their supervision by an official distributor.
20. If you leave the TTMA, put it somewhere where it does not preclude others. Keep the whole
machine in transport position. Close all hatches well for unauthorized persons. Take your
keys with you.
21. The operator of the machine may not be under the influence of alcohol or narcotic drugs.

7Supporting vehicle and adjustment
It is important that the TTMA is mounted correctly behind the supporting vehicle. Mounting the
TTMA behind the vehicle can be done with a DIN connector and Rockinger. Make sure the
connection with the truck is done or checked by Verdegro or a distributor, and that a certificate is
given. Also make sure the bumper of the truck is correctly installed. The TTMA is tested with a 40mm
DIN coupling, so a 50mm will also be correct.
It is allowed that a country overrules the specifications of the supporting vehicle, for example (valid
for the Verdegro TTMA):
Sweden: Lower limit weight of the truck 9.000 kgs, upper limit by manufacturer4
Belgium: Lower limit weight of the truck 8.000 kgs, upper limit 9.440 kgs
Make sure the DIN coupling is correctly installed. Only use couplings certified
or delivered byVerdegro
Make sure the ROCKINGER and bumper are correctly installed!!!
