ABSTRACT:
Apparatus for receiving and dumping a top-unloading car. Cradle track extends from a car receiving position to a car dumping position, and is inclined downwardly from the car-receiving position. A car-receiving cradle assembly movably mounted on the cradle track includes rocker members with arcuate peripheries for contact with and support by the cradle track. Car rails support a loaded car on the cradle assembly with the combined center of gravity of the car, of its load and of the cradle assembly being located relative to the peripheries of the rocker members such that the cradle assembly, with a loaded car thereon, can roll by gravity action from a normal vertical position at the car-receiving position through an angle in the range of about 70 to about 110 degrees and, with an emptied car thereon, can roll by gravity action from the car-dumping position to return to a position within that range. Through hydraulic cylinders connected with the cradle assembly, liquid is applied under pressure for moving the cradle from a position in the above-indicated range to car-dumping position and for moving the cradle from a position in the above-indicated range to car-receiving position.
