That is an interesting attenuator. I usually see stake side trucks with attenuators that have a truck load of cones, just a tractor is kind of useless can't do much.

I've seen attenuators on just trucks with just a cab and chassis, on dump trucks, flatbeds, stakebeds. Never one like that... as far as being useless... What is their purpose? Move traffic over and provide protection to workers, so honestly, if that truck stops a car from hitting workers and absorbs the impact, its doing its job. Just because it doesn't double as a cone truck doesn't make it useless. There is a video here... http://www.jtechlighting.com/ ... if it does that it is doing its job.

There called crash trucks and in Virginia and most east coast states if your not working behind jersey barriers you have to have one at the start of your site by law. Justin

Here on the east coast those trucks spend most of their life just sitting at the beginning of the pattern. They're usually old tractors or dump trucks converted to this purpose. The stake trucks with crash attenuators that are used to lay out the pattern are different.

That Mack TMA has a lot of potential. There was a company around had who have 4 Mack R's with TMA's on them, all with fifth wheels. They all had reconstructed titles. Most likely that Mack was used a truck tractor/prime mover and they no longer had a use for it, so they converted it into a TMA. A lot of companies uses cheap/spare trucks because well they would be totaled if a vehicle hit the crash cushion in the rear hard and fast enough, and if the truck was parked in front of a jersey barrier. Nice finds Vin.

Hi in NJ and other states you cannot have anything in the bed on a TMA and in NJ you need a PE seal on the attachement of the ballast to the truck frame !!! The DOT and State Police will give you a ticket for anything in the bed even a cone . A 3 person crew is min and on the parkway you need 2 TMA and a cone truck . John

The American A100-HC was truely American built as opposed to an Asian import badged as an American. American was no longer American Hoist but rather American Crane and this was one of their first efforts to design a hydrualically winced machine. Ultimately their finances forced the sale into the Terex fold.
Regarding the Mack, the size and substance of the truck can help protect the people working in front of it. When you own the older chassis why purchase a high milage former van truck chassis to use and you gain the braking of an additional axle when parked. Those firms that have older heavy chassis tend to use them over the lighter truck.
