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.
