This subclass is indented under subclass 14. Where the operation is effected by a movement of the vehicle
as a whole or through the movement of some substantial part thereof.
This subclass is indented under the class definition. Where the load-receptacle is capable of assuming an inclined
or tilted position to permit the load to slide off the inclined
bottom of the receptacle.
This subclass is indented under subclass 17. Devices in which the load-receptacle is (1) selectively
tiltable about at least one of a plurality of pivot axes or (2)
tiltable about an axis which progressively changes concurrently
with the tilting (e.g., rocking support).
This subclass is indented under subclass 17.5. Devices in which the load-receptacle is optionally tiltable
in a selected one of a plurality of different directions (e.g.,
towards either side).
This subclass is indented under subclass 17.6. Devices wherein the pivot axis about which the load-receptacle
is tilted, during at least one tilting cycle, sequentially moves
from one to another of a plurality of fulcrum points, (e.g., rocking
support).
This subclass is indented under subclass 17. Provided with additional means for effecting the tilting
of the load-receptacle or returning it to its load-carrying position,
or both.
This subclass is indented under subclass 19. Where the operation is effected by a movement of the vehicle
as a whole or through the movement of some substantial part thereof.
This subclass is indented under subclass 17. Those of the type indicated where means is provided to operate
an end-gate or cover through the dumping operation of the vehicle or
means for doing so manually where such means is located at a distance
from the end-gate or cover.
This subclass is indented under the class definition. Consisting of a box-container having a movable part or parts
adapted, when moved, to permit the load to fall by gravity.
This subclass is indented under subclass 24. Where the bottom of the load-receptacle can be opened to
permit the load to drop by gravity to a position under the vehicle.
This subclass is indented under subclass 24. Where the bottom of the load-carrier consists of a door
or doors hinged to open and permit the load to drop.
