Abstract

A safety trailer including first and second platforms, at least one of said 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 lower bracing section comprising a single horizontal beam, two diagonal braces and a plurality of cross-braces, to allow workers in the protected work area to access a portion of the area under 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; and
(c) wherein each wall section has a lower bracing section comprising a single horizontal beam, two diagonal braces and a plurality of cross-braces, to allow workers in the protected work area to access a portion of the area under the wall section.

2. The safety trailer of claim 1 , wherein each wall section has first and second end members, each of the first and second end members comprising an outwardly projecting alignment member and an alignment-receiving member, the first and second end members having the alignment and alignment-receiving members positioned in opposing configurations.

3. The safety trailer of claim 2 , wherein the outwardly projecting alignment member is a dowel.

4. The safety trailer of claim 2 , wherein the alignment-receiving member is a dowel receiver hole.

5. The safety trailer of claim 1 , wherein the wall sections are interconnected through a screw-and-bolt connection using bolt holes associated with ends of the wall.

6. The safety trailer of claim 1 , wherein each wall section has a plurality of interconnected levels, each level comprising first and second longitudinal members, a plurality of truss members interconnecting the first and second longitudinal members and wherein the first and second longitudinal members are connected to the first and second end members.

7. The safety trailer of claim 5 , wherein each wall section comprises an outer plate covering a length of the wall section and engaging the first and second longitudinal members.

8. The safety 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.

9. The trailer of claim 7 , 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.

10. 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.

11. The trailer of claim 9 , wherein the adjustment member is at least one of a hydraulically and pneumatically adjustable piston.

12. The safety trailer of claim 1 , wherein a bottom edge of each wall section is positioned about 10 to about 14 inches above a surface upon which the trailer is parked; a top edge of each wall section is positioned from about 3.5 feet to about 4 feet above the surface; and a height of the wall sections from the bottom edge to the top edge ranges from about 2.5 feet to about 3 feet.

13. The safety trailer of claim 1 , wherein the barrier is not supported above the surface by stands.

14. The safety trailer of claim 1 , wherein a thickness of each wall section ranges from about 18 to about 30 inches.

15. The safety trailer of claim 1 , wherein a length of each of the wall sections ranges from about 10 to about 30 feet.

16. The safety trailer of claim 1 , wherein a common side of the first and second platforms and barrier is substantially planar to direct a motorized vehicle impacting the common side away from the protected area.
