Abstract

In one embodiment, a safety trailer has semi-tractor hitches at both ends and a safety wall that is fixed to one side of the trailer. That side, however, can be changed to the right or left side of the road, depending on the end to which the truck attaches. A caboose can be attached at the end of the trailer opposite the tractor to provide additional lighting and impact protection. Optionally, the trailer can be equipped with overhead protection, lighting, ventilation, onboard hydraulics, compressors, generators and other equipment, as well as related fuel, water, storage and restroom facilities and other amenities.

First claim

I claim:

1. A mobile barrier comprising:
(a) first and second platforms, each of said first and second platforms having at least one set of wheels;
(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) wherein each wall section has at least one of the following features:
(c1) the wall section further comprises an upper wall extension that increases a height of the wall section; or
(c2) the wall section further comprises a lower wall extension that occupies at least part of a gap between a bottom of the wall section and a travel surface; and

wherein the wall sections and first and second platforms are plumbed with pumps to effect hydraulic displacement of the wall extensions.

2. The mobile barrier of claim 1 , wherein the wall section comprises an upper wall extension.

3. The mobile barrier of claim 2 , wherein the upper wall extension is moved into and out of position by one or more of air, hydraulics and/or springs and levers with electrical or mechanical switches.

4. The mobile barrier of claim 1 , wherein the wall section comprises a lower wall extension.

5. The mobile barrier of claim 4 , wherein the lower wall extension is moved into and out of position by one or more of air, hydraulics and/or springs and levers with electrical or mechanical switches.

6. The mobile barrier of claim 4 , wherein the lower wall extension is built into the outside of the wall sections and rotates into position to close the gap between ground and wall section.

7. The mobile barrier of claim 4 , wherein the lower wall extension is built into the inside of the wall sections and rotates into position to close the gap between ground and wall section.

8. The mobile barrier of claim 4 , wherein the lower wall extension is built into the outside of the wall sections and slides down into position to close the gap between ground and wall section.

9. The mobile barrier of claim 4 , wherein the lower wall extension is built into the inside of the wall sections and slides down into position to close the gap between ground and wall section.

10. The mobile barrier of claim 4 , wherein the lower wall extension is built into the bottom of the wall sections and rotates into position to close the gap between ground and wall section.

11. The mobile barrier of claim 4 , wherein the lower wall extension is built into the bottom of the wall sections and slides down into position to close the gap between ground and wall section.

12. The mobile barrier of claim 1 wherein the wall section comprises an upper wall extension and said upper wall extension slides into position.

13. The mobile barrier of claim 1 wherein the wall section comprises a lower wall extension and said lower wall extension slides into position.

14. The mobile barrier of claim 1 wherein the wall sections are strengthened by means selected from the group comprising: making end plates of stronger material, making the end plates of thicker material, making the end plates larger for use with more and/or larger dowels and/or bolts, gusseting the end plates to a main beam structure of the wall sections.

15. The mobile barrier of claim 1 wherein the wall sections are a preferred height of at least about 4.1 feet, more preferably of at least about 4.25 feet, and even more preferably at least about 4.5 feet.

16. The mobile barrier of claim 1 wherein the first or second platforms includes one or more features selected from the group comprising stationary turrets, rotating turrets, bullet/blast proofed enclosures, large caliber guns, small caliber guns, attachments for cameras, mine clearing devices, mine detecting devices, and other on- site, and remotely viewable and/or controllable equipment.

17. The mobile barrier of claim 1 wherein the barrier further comprises trailer stands that automatically raise and/or lower via air, hydraulics, electrical or other mechanical means.

18. The mobile barrier of claim 1 wherein the barrier has protective wall sections deployed on both sides of the first and second platforms with a fully enclosed protected work area being positioned in the center.

19. A mobile barrier comprising:
(a) first and second platforms, each of said first and second platforms having at least one set of wheels;
(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) wherein each wall section has at least one of the following features:
(c1) the wall section further comprises an upper wall extension that increases a height of the wall section; or
(c2) the wall section further comprises a lower wall extension that occupies at least part of a gap between a bottom of the wall section and a travel surface; and

wherein the wall sections and first and second platforms are provided with electric motors to effect displacement of the wall extensions.
