Speed trailers, also known as digital speed limit or variable speed limit trailers, are portable traffic devices that display a changeable speed limit near work zones.
Through wireless communication, the trailer display can be changed from any remote location allowing for an instant speed limit change. All of the electronic components can be easily replaced if needed for simple maintenance.
No matter where your construction job takes you, the variable speed limit trailer can be conveniently towed and set up in any location. The strong steel trailer is built to last with a full suspension system and a smooth powder coat finish. When the trailer is locked into position with the sign-up, it is 15’ 2” in height. For convenient transportation, the sign folds down for a total height of 7’ 6”.
Our portable digital speed limit signs are surprisingly sustainable and come equipped with a 140-watt solar panel array. The solar panel is mounted on the very top of the sign for maximum sun exposure, plus the battery bank size is enough to power the trailer for 30 days untouched. During long construction projects, you won’t have too much to worry about when it comes to powering your speed limit sign.
The setup process for this trailer is very simple and can be done by a single person. There are four extendable support legs attached to the frame that flips vertically and can be cranked to your desired level. To raise the sign from the folded position, you can use the manual winch system on the side of the frame.
