ABSTRACT:
A trailer comprises a container supported between a pair of scissors lifts having first and second arms movable about a pivot by a ram. The arms support the container by a pair of rollers and a mounting lug. The mounting lug comprises a lug on the container for engagement with a pair of U-shaped slots, a tilt slot and a lift slot. The lug engages the lift slot when the trailer is to be lifted. For tilting the lug engages the tilt slot thereby causing the rollers to disengage the container to permit tilting.
