Click here for a printable version of this file

SECTION I - CLASS DEFINITION

Vehicles other than track or rail vehicles and commonly known as dumping-wagons, dump-carts, dumping-sleighs, dumping-barrows, chute-wagons, etc., adapted for carrying a freight-load and so constructed and arranged that by manipulation of the whole or a part of the vehicle the load or some considerable part thereof will move by gravity to unload the vehicle.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

For dump-cars see Class 105, Railway Rolling Stock, subclass 239, and indented subclasses.

For a self-loading or unloading vehicle having a load receiving portion which is pivotable relative to the horizontal, see Class 414, Material Article Handling, subclasses 469+, and see especially the search note to this class (298) which appears in subclass 469.

For a device for emptying a portable receptacle, see Class 414, Material or Article Handling, subclasses 403+, and see particularly indented subclasses 419+.
