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.

Abstract: Embodiments of a safety trailer are shown and described. The safety trailer includes a trailer body defining a protected workzone, and having a first end and a second end and king pins at both the first and second ends. Also provided is a removable caboose engageable with either of the king pins at the first and second ends of the trailer body, the caboose having a fixed king pin plate, a nose portion and at least one axle and wheels. The fixed king pin plate distributes at least a portion of the force of a vehicle colliding with the safety trailer. The caboose is also provided with a caboose receiving member, the caboose receiving member comprising an alignment device. The caboose further comprises 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.
