A double container trailer is shown having a main trailer frame including a front trailer frame and a rear trailer frame, both of which define a top support surface. The rear trailer frame has a tilt frame pivotally mounted thereon for supporting a first load bearing container. A pivot mechanism is connected between the rear trailer frame and the tilt frame for pivoting the tilt frame and its associated container abou t a pivot point located on the rear trailer frame. A primary cable drive located on the rear trailer frame engages a first load bearing container for transporting the first container onto the top support surface of the main trailer frame to an initial transport position. A secondary cable drive engages the first load bearing container and moves the container to a final transport position forward of the initial transport position. The secondary drive includes a winch drum having a threaded external surface which defines a series of thread grooves and a forward cable, the forward cable being wound onto the threaded external surface of the winch drum and extending in either of opposite directions between spaced sheaves located on the trailer main frame.
