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.
Claims29
A safety trailer, comprising:
- (a) first and second removably interconnected platforms, at least one of the first and second platforms being engaged with an axle and wheels, the first and second platforms defining a trailer;
- and
- (b) a plurality of wall sections supported by the trailer, the wall sections, when deployed to form a barrier wall, are positioned between the first and second interconnected platforms
- (c) wherein at least one of the following is true:
- (c1) the trailer supports a ballast member, the ballast member being positioned near a first side of the trailer and the ballast member near a second, opposing side of the trailer, the ballast member offsetting, at least partially, a weight of the plurality of wall sections, and
- (c2) the axle of the trailer is engaged with a vertical adjustment member, the vertical adjustment member selectively adjusting a vertical position of a surface of the trailer.
3 more elements
A safety trailer, comprising:
- (a) first and second platforms;
- (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) 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 being connected to an end member;
- (c2) 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;
- (c3) 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;
- and
- (c4) 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.
5 more elements
A trailer, comprising:
- a) a trailer body;
- b) a removable caboose engageable with the trailer body, the caboose having a nose portion and at least one axle and wheels;
- and
- c) a caboose receiving member, the caboose receiving member comprising an alignment device, wherein, in a first mode when the caboose is moved into engagement with the trailer body, the alignment device orients the caboose with a king pin mounted on the trailer body and, in a second mode when the caboose is engaged with the trailer body, the alignment device maintains a desired orientation of the caboose with the trailer.
1 more element
A safety system, comprising:
- (c) a vehicle;
- (d) first and second platforms;
- (e) a barrier engaged with the first and second platforms, the barrier and first and second platforms forming a protected work space;
- and
- (f) a caboose, wherein the vehicle and caboose are engaged with the first and second platforms, respectively, wherein the vehicle has a movable king pin plate engaged with a first king pin on the first platform, and wherein the caboose has a fixed king pin plate engaged with a second king pin on the second platform.
2 more elements
A safety system, comprising:
- (a) a vehicle;
- (b) first and second platforms;
- (c) a barrier engaged with the first and second platforms, the barrier and first and second platforms forming a protected work space;
- and
- (d) a caboose, wherein the vehicle and caboose are engaged with the first and second platforms, respectively, wherein the vehicle and caboose have braking systems that operate independently.
2 more elements
A trailer, comprising:
- (a) first and second platforms;
- (b) a barrier engaged with the first and second platforms, the barrier and first and second platforms forming a protected work space, wherein the barrier is formed by a plurality of interconnected wall sections and wherein the interconnected wall sections slidably engage one another.
A trailer, comprising:
- (a) first and second platforms;
- (b) a barrier engaged with the first and second platforms, the barrier and first and second platforms forming a protected work space, wherein the barrier is formed by a plurality of interconnected wall sections and wherein the interconnected wall sections telescopically engage one another.
