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.
