are tilted to match the angle of the inclined side of the pit,
and the truck body is pulled out of the pit and onto the
truck. Filipoff lacks “leg means for supporting the front end
of the truck equipment above the ground” at a given height and
at a given angle, as is set forth in claim 12. Filipoff also
lacks the required
actuator means . . . to raise the front end of the
[truck] ramp means and tilt said ramp means
substantially at said given angle so as to enable
engagement of a lower rear portion of the tilted
ramp means with an upper front portion of the guide
means [of the truck equipment] by moving the truck
frame rearwardly toward the truck equipment
(emphasis added).
Thus, the Filipoff system differs in concept from that set
forth in claim 12, in that it does not move the truck
rearwardly into a position wherein the lower rear portion of
the tilted ramp engages the upper front portion of the
equipment, but simply pulls the equipment up onto the truck.
Tarrant discloses a loading system wherein the truck
equipment to be loaded is elevated above the ground, supported
by front and rear pairs of legs, and the truck is driven
completely under it so that the entire under-surface of the
equipment is engaged by the entire upper surface of the truck
