Patent ID: 7651042

Claim:
A mobile slurry apparatus for creating a slurry from oil sand ore, comprising: a frame having a lower base for supporting the frame; a slurry box supported by the frame, wherein the slurry box defines a first center of gravity for the slurry apparatus, the first center of gravity being in a first region located proximate to the slurry box when the slurry box contains a slurry; and means for receiving water for communication with the ore or the slurry box, whereby water is mixed with the ore to form a slurry that is retained in the slurry box when the slurry apparatus is in operation; the frame comprising a lower base having a first set of spaced apart support points for supporting the frame in a stationary mode, and a second set of spaced apart support points for supporting the frame in a moving mode, the second set of spaced apart support points each being closer together than the first set of support points and defining a single lifting region disposed beneath a second center of gravity of the slurry apparatus in a moving mode when the slurry box is empty, the single lifting region being located proximate to a center of the lower base with a portion of the lifting region located in the center of the lower base; wherein the single lifting region is defined by the second set of support points so that a single moving device can be positioned beneath the second set of support points for lifting the slurry apparatus under the single lifting region and for moving the slurry apparatus while lifting the slurry apparatus under the single lifting region.
