Important Introductory Notes
Proper assembly of the SS180 TMA®system is essential to achieve performance of the system
under appropriate federal and state criteria. These instructions should be read in their entirety
and understood before assembling the SS180 TMA®system. These instructions are to be used
only in conjunction with the assembly of the SS180 TMA®system and are for standard
assemblies only as specified by the applicable highway authority. In the event your system
assembly requires or involves deviation from standard parameters or, during the assembly
process a question arises, please contact the appropriate highway authority that specified this
system at this particular location for guidance. Energy Absorption Systems is available for
consultation with that agency. These instructions are intended for an individual who is qualified
to both read and accurately interpret them as written. They are intended for the individual who
is experienced and skilled in the assembly of highway products which are specified and
selected by the highway authority. If there are deviations, alterations, or departures from the
assembly protocol specified in this Manual, the device may not perform as it was tested and
accepted.
A set of product drawings will be supplied by Energy Absorption Systems, when requested.
The drawings will be for each section of the assembly. These drawings should be reviewed and
studied thoroughly by a qualified individual who is skilled in interpreting them before the start of
any assembly.

System Overview
The SS180 TMA®system is a Truck Mounted Attenuator (TMA) shown to reduce the risk of
injury to passengers of an errant vehicle and to the driver of the truck to which the system is
attached when the system is impacted within the applicable NCHRP 350 criteria. The system
mounts on the rear of a truck and may be used in stationary applications (e.g. as a truck block
in a work zone) and mobile operations (e.g. striping, sweeping, plowing, etc.).
Important: Read safety instructions thoroughly and follow the assembly
directions and suggested safe practices before assembling, maintaining, or
repairing the SS180 TMA®system. Failure to follow this warning can result in
serious injury or death to the worker and/or bystanders. It further compromises
the acceptance of this system by the FHWA. Please keep these instructions for
later use and reference by anyone involved in the assembly of the product. Use
the traffic control plan set for the by the highway authority in charge of this work
area.
Warning: Ensure that all of the SS180 TMA®system Warnings, Cautions, and
Important Statements within the SS180 TMA®Manual are completely followed.
Failure to follow this warning could result in serious injury or death in the event
of a collision.

Limitations and Warnings
Energy Absorption Systems, in compliance with the National Cooperative Research Highway
Program 350 (NCHRP Report 350) “Recommended Procedures for the Safety Performance of
Highway Safety Features”, contracts with FHWA approved testing facilities to perform crash
tests, evaluation of tests, and submittal of results to the Federal Highway Administration for
review.
The SS180 TMA®system was tested to meet the impact criteria, requirements, and guidelines
of NCHRP Report 350. These tests, specifically set forth by FHWA, evaluate product
performance by simulating those impacts outlined by NCHRP Report 350 involving a typical
range of vehicles on our roadways, from lightweight cars (approx. 820kg [1800 lb.]) to full size
pickup trucks (approx. 2000 kg [4400 lb.]) as specified by the FHWA. A product can be certified
for multiple Test Levels. The SS180 TMA®is certified to the Test Level as shown below:
Test Level 3: 100 km/h [62 mph]
These FHWA directed tests are not intended to represent the performance of systems
when impacted by every vehicle type or every impact condition existing on the roadway.
This system is tested only to the test matrix criteria of NCHRP 350 as approved by
FHWA.
Energy Absorption Systems does not represent nor warrant that the results of these controlled
tests show that vehicle impacts with the products would necessarily avoid injury to person(s) or
property. Impacts that exceed the specifications of the system may not result in acceptable
crash performance as outlined in NCHRP Report 350, relative to structural adequacy, occupant
risk and vehicle trajectory. Energy Absorption Systems expressly disclaims any warrant or
liability for injury or damage to persons or property resulting from any impact, collision, or
harmful contact with products, other vehicles, or nearby hazards or objects by any vehicle,
object or person, whether or not the products were installed by or under the direction of Energy
Absorption Systems or by third parties.
SS180 TMA®system is intended to be assembled, delineated, and maintained in accordance
with specific State and Federal guidelines. Energy Absorption Systems offers a reflective
delineator panel for its TMA line of products. However, the material is only intended to
supplement delineation required by the Department of Transportation’s “Manual on Uniform
Traffic Control Devices” (MUTCD). The appropriate highway authority approved engineer
should be careful to properly select, assemble, and maintain the product. Careful evaluation of
the speed, traffic direction, and visibility are some of the elements that require evaluation in the
proper selection of a safety appurtenance by the appropriate specifying highway authority.
After an impact occurs, the product must be repaired to its original condition as soon as
possible. When a safety product is impacted, it is mandatory that the highway authority inspect
all the components for damage and repair and/or replace components as necessary. If the
system is not repairable, a complete system replacement is required.

1. The TMA shall be rigidly fastened to the truck. In the horizontal position, the bottom of
the TMA shall be 280 to 330 mm [11" to 13"] from the ground and level (See Figure 3).
The TMA must be left in the unfolded position whenever possible. The TMA can only
absorb the energy of an impacting vehicle when in the unfolded position.
Figure 3
2. Jacks shall be used to support the TMA when it is detached from the truck. The Jacks
must be stored while the TMA is attached to the truck. The Jacks can be stored on the
brackets provided on the support frame (See Figure 3).
3. Make sure all pivot pins are in position and that all retaining pins are assembled
correctly (See Figure 4).
Figure 4
The SS180 TMA
®
shall be deployed in the unfolded position: At all times while operating as
either a Barrier Vehicle or Shadow Vehicle.
The SS180 TMA
®
shall be in the "unfolded" position when: transporting short distances at a
low speed, transporting at a speed much lower than adjacent traffic, and transporting in areas
where vehicle ride characteristics and maneuverability are maintainable.
The SS180 TMA
®
shall be in the "folded" position when: transporting long distances at a high
speed, transporting at a speed near the speed of adjacent traffic, and transporting under
conditions of compromised maneuverability typically when the large turning radius clearance
needed for the extended TMA is not safe.

4. The SS180 TMA
®
is intended to support its own weight and dissipate the kinetic energy
of errant vehicles per NCHRP 350 criteria. Do not drag the TMA or place anything on its
top or damage will result. Do not sit, stand or lean on any part of the TMA (See Figures
5 & 6).
Figure 5
Figure 6
5. Before raising or lowering the TMA, the operator shall be fully trained as to its proper
operation. All operators shall fully understand the contents of this Manual prior to
operating the system. The operator should never stand under the TMA when it is
raised, or attempting to lower it.
6. Folding the TMA provides the best maneuverability and driving characteristics. It is
advisable, during restricted city driving and high-speed travel, to have the TMA folded to
its storage position. Refer to local agency policies as required for additional guidance.
Unfold the system either before, or as soon as possible after, entering a job site or
beginning shadow vehicle operations. It is required that the support vehicle be stopped
for TMA folding and unfolding.
7. Be sure all persons are standing clear before folding or unfolding the TMA. Be sure the
system is stopped in full folded position before allowing anyone directly behind the
folded system.
