Abstract

A plural container trailer has hydraulic systems for loading, unloading, and otherwise handling removable containers. The trailer has a bed long enough to carry two containers in line. The trailer has an undercarriage carrying a rear tilt frame. A forward mounted cable and winch system operates over the rear tilt frame to pull a first or forward container from the ground fully to a front docking position on the trailer bed. The forward cable remains connected to the forward container and it is not necessary to disengage a rear pulling mechanism and recouple the container to a front pulling mechanism. A second container-hoisting system loads and unloads a second container between the ground and the tilt frame. A slider mechanism engages against the front wall of the first container, and is moved forward as the first container is moved toward the front docking position. The slider mechanism drives the first container rearward, onto the empty tilt frame, for unloading the first container to the ground via the tilt frame and taut cable of the forward cable and winch system.
