Abstract

A safety trailer is shown, the device 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 longitudinal member extending a length of the wall section, the longitudinal member being positioned at the approximate position of a bumper of a vehicle colliding with 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 and at least one of the first and second platforms having a king pin at an end thereof;
(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 longitudinal member extending a length of the wall section, the longitudinal member being positioned at the approximate position of a bumper of a vehicle colliding with the wall section; and
(d) a removable caboose engageable with the king pin, the caboose having a fixed king pin plate, a nose portion and at least one axle and wheels, wherein said fixed king pin plate distributes at least a portion of the force of a vehicle colliding with the safety trailer, the caboose further comprising at least one of: a vertical adjustment member adapted to maintain a level ride height, provide additional ground clearance and level the caboose; and an auxiliary mechanism adapted to engage a caboose brake system.

2. The trailer of claim 1 , wherein the selected wall section comprises an outer plate covering a length of the wall section and engaging the longitudinal member.

3. 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.

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

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

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