Abstract: A vehicle body having a plurality of temperature controlled compartments is provided. The vehicle body has a longitudinally extending interior cavity including a front end, a rear end and two sides extending longitudinally between the front and rear ends. The interior of the vehicle body is partitioned into a pair of longitudinally extending compartments by removable panels, and each longitudinal compartment is selectively variable between a plurality of lengths by removable bulkheads. A first closed fluid circuit provides an air flow through one compartment to maintain such compartment substantially at a first controlled temperature designed for refrigerated goods, while a second closed fluid circuit, separate from the first closed fluid circuit, provides an air flow through the other compartment to maintain such compartment substantially at a second controlled temperature designed for frozen goods. An opening in the rear of the trailer allows loading and unloading of the goods from either compartment.

Abstract: A ramp lifter device is provided which is adapted to elevate the end of a loading ramp from its initial, extended position to the floor height of a trailer. A trailer chassis provides a storage area for the loading ramp between longitudinal frame members. A ramp carrier box is secured between opposing frame members of the trailer chassis. The ramp includes a ramp carriage having extension rods that are slidingly received along the ramp carrier box. The ramp lifter device includes a reinforcement member attached to a bottom cross member towards one end of the ramp, and a handle. Selectively applying a downward force on the handle forces a pivot rod on the ramp lifter device against the ramp carriage extension rods, which pivots the reinforcement member upwardly, and hence elevates the end of the ramp to the level of the trailer floor. The loading ramp can be manually moved forward and lowered so that ramp hooks on the end of the ramp engage corresponding ramp pockets on the end of the trailer body.
