Mounting assembly for a controllably movable fluid tank

In a fluid tank mounting apparatus for connecting the fluid tank to a vehicle, the improvement comprising:

• a vehicle frame;
• a structure pivotally movable relative to the frame from a closed position in a direction towards said fluid tank to an open position;
• first means for pivotally connecting a first preselected portion of the fluid tank to the pivotally movable structure of the vehicle;
• and
• second means for pivotally connecting a second preselected portion of the fluid tank to the frame of the vehicle for moving the fluid tank between a first position at which said fluid tank is at a first position generally superjacent said pivotally movable structure and a second position at which said fluid tank is displaced from the first position rearwardly, in a direction generally away from the pivotally movable structure, in response to pivotal movement of said structure and maintaining the fluid tank at substantially a preselected attitude at and between said first and second fluid tank positions at which a preselected portion of the fluid tank is maintained at a higher elevation than other tank portions.
