A method and apparatus for transporting roll-off containers is disclosed wherein a special trailer is fabricated with longitudinally extending main rails and a plurality of inside rollers and outside rollers rotatively affixed to the main rails. A plurality of six roll-off containers are stacked to form two similar nests of three containers each, with the lowermost container of each nest oriented in horizontal alignment. The two nests of containers are placed upon the trailer in longitudinal juxtaposition in a location wherein the bottom rails of the lowermost containers rest upon either the inside or outside rollers. During unloading, the trailer is backed and suddenly stopped in stages to employ inertial forces to move the nests of containers relative to the trailer.

A method for transporting a plurality of large containers of the type including a floor, a left sidewall, a right sidewall and a front wall extending from the floor to define an open top, a removable rear door providing an open rear and at least one bottom rail affixed to the floor, on a trailer of the type having at least one main rail having a top surface and rollers below the top surface, comprising the steps of stacking a first plurality of three containers together to form a first nest, the stacking comprising orienting a first container with its floor in horizontal alignment and the second and third containers with their floors in vertical alignment, interleaving the second and third containers with their respective left sidewalls in mutual contact and contacting the floor of the first container with a left sidewall of one of the other two containers, the stacking further comprising oppositely facing the at least one bottom rail of each of the second and third containers to the sides; stacking a second plurality of three containers to form a second nest, the stacking of the second plurality comprising orienting a first container of the second plurality with its floor in horizontal alignment and the second and third containers of the second plurality with their floors in vertical alignment, interleaving the said second and third containers with their respective left walls in mutual contact and contacting the floor of the said first container with a left sidewall of one of the other said two containers, the stacking of the second plurality further comprising oppositely facing the at least one bottom rail of each of the second and third containers of the second plurality to the side; constructing the forward portion of the trailer above the rearward portion of the trailer and causing the said at least one main rail to normally slope from front to rear to facilitate unloading procedures; positioning the first nest upon a forward portion of the trailer and resting the bottom rail of the first container of the first plurality upon at least some of the rollers; positioning the second nest upon a rearward portion of the trailer in longitudinal juxtaposition to the first nest and resting the bottom rail of the first container of the second plurality upon other of the rollers; and moving the trailer in sloped orientation to simultaneously transport a plurality of six large containers.
