ABSTRACT:
A trailer assembly for carrying overwidth loads such as large rectangular concrete slabs. The trailer includes two separate units, a front unit and a rear unit. Each unit includes a frame mounted on a set of tandem wheels. The front unit has upper and lower frames rotatably connected together, allowing the wheels to turn with respect to the upper frame. A tongue is hingedly connected to the front unit. It has a hitch for connection to the towing vehicle and a compression device to apply weight to the hitch for compressive connection with the towing vehicle. Longitudinal cross members are mounted across the front and rear units to support the load. The cross members can be removed and stored parallel to the length of the units for legal width return trip towing. On return trip, the rear unit is towed reverse to the direction towed while loaded. Also disclosed is an embodiment employing two units the same or similar to the front unit to enable being moved laterally to facilitate parking in close space.
