Development of a Roll-Off Container Handling and Dumping System (Ground Level or into a Railroad Car) for Off-Highway Articulated Trucks

This paper describes the development and manufacture of roll-off container handling systems for off-highway articulated trucks. This presentation reviews systems incorporating four unique products covering various roll-off container handling alternatives. The various components described and, depending on the style of the system, incorporated into a system are:

1. 1.
   An off-highway truck “J”-Hook arrangement for picking roll-off containers up off of the ground and pulling them onto a haulage vehicle.
2. 2.
   An automatic tailgate locking and opening system for roll-off containers vs. a manual vehicle driver dependent door/tailgate system.
3. 3.
   A scissors lift for lifting roll-off containers to be dumped into various other vessels (railroad gondola cars, etc.).
4. 4.
   A unique “J”-Hook interface for standard 20-ft. intermodal roll-off shipping containers so they can be hooked onto and handled with a “J”-Hook.

Both the automatic locking/unlocking tailgate and the scissors lift are features which may or may not be incorporated in every unit. The equipment discussed in this paper opens new avenues for off-highway trucks in steel mills, landfills, quarries, etc.
