PRODUCT DESCRIPTION 

(e New Hardware or 

Significant Modification 

(' Modification to 

Existing Hardware 

The TTMA-200 is trailer attenuator designed to dissipate the kinetic energy of an impacting vehicle to reduce 

the severity of a crash. As the impact head and mandrel are pushed forward into the first tube, the tapered 

mandrel bursts the first tube at the corners into four (4) straps. The bursting of the first tube dissipates the 

kinetic energy of the impacting vehicle. The trailer attenuator has a length of 23.6ft (7.2 m) with an optional 

hitch extension its total tested length was 24.9 ft. (7.6 m) and a max width of 8.0 ft. (2.4 m). The TTMA-200 is 

supported by a wheel and axle assembly and is attached to the support truck with a lunette ring. 

All testing of the TTMA-200 was conducted with an optional 4.0 ft. x 8.0 ft. (1 .2 m x 2.4 m) arrow board and 

arrow board frame that attached to the trailer frame assembly. The arrow board frame was attached to the 

trailer frame assembly with two (2) 5/8" grade 5 bolts and six (6) 1/2" grade 5 bolts. The arrow board was 

secured to the arrow board frame with five (5) 3/8" grade 5 bolts. An optional 16.0 in. (406 mm) hitch extension 

bolted to the trailer frame assembly with four (4) 5/8" grade 5 bolts. The TTMA-200 lunette ring was inserted 

into a standard 8-ton pintle hitch mounted on the support truck at a height of 19.5 in. (495 mm). Complete 

detail of the assemblies can be found in the manufacturer's drawings.
