Abstract

A safety trailer including first and second platforms, at least one of the first and second platforms having an axle and wheels attached thereto; a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer; and wherein each wall section has a plurality of full height and partial height wall members, the full height wall members extending substantially the height and width of the wall section and the partial height wall members extending substantially the width but less than the height of the wall section, the full height and partial height members alternating along a length of the wall section.

First claim

The invention claimed is:

1. A safety trailer, comprising:
(a) first and second platforms, at least one of said first and second platforms having an axle and wheels attached thereto;
(b) a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer;
(c) and wherein each wall section has a plurality of full height and partial height wall members, the full height wall members extending substantially the height and width of the wall section and the partial height wall members extending substantially the width but less than the height of the wall section, the full height and partial height members alternating along a length of the wall section.

2. The trailer of claim 1 , wherein the trailer supports a ballast member, the ballast member being positioned near a first side of the trailer and the plurality of wall sections near a second, opposing side of the trailer, the ballast member offsetting, at least partially, a weight of the plurality of wall sections.

3. The trailer of claim 2 , wherein the ballast member is on a first side of a longitudinal axis of the trailer and the plurality of wall sections on a second opposing side of the longitudinal axis.

4. The trailer of claim 1 , wherein the at least one axle is engaged with a vertical adjustment member, the vertical adjustment member selectively adjusting a vertical position of a surface of the trailer.

5. The trailer of claim 4 , wherein the adjustment member is at least one of a hydraulically and pneumatically adjustable piston.

6. The trailer of claim 1 , wherein the interconnected wall sections slidably engage one another.
