Claim 1
Independent Claim 246 words
A fork lift truck of the type including a chassis mounted for movement over a surface by front and rear pairs of wheels, power means for driving the truck, transmission means, a hydraulic fork lift at one end of the chassis, a driver's seat, and steering and control means for controlling operation of the truck, the improvement wherein a portion only of said chassis extending between said front and rear wheels is in the form of an arch including an upper portion which is located between and substantially above the level of said pairs of wheels and steeply sloping front and rear portions, said arch-shaped portion lying essentially on one side of the vertical longitudinal median plane of the truck, the portion of the chassis on the other side of said longitudinal median plane lying substantially on a level with the chassis ends at the pairs of wheels, means mounting said power means underneath said upper portion of said chassis arch and between said pairs of wheels, said driver's seat including a chair-like portion mounted for pivotal movement about a generally vertical axis above said upper portion of said arch, a foot-rest portion spaced substantially below said upper portion of said arch and means joining said foot-rest portion and said chair-like portion and extending in outwardly spaced relation to said steeply sloping portiions of said arch, and said steering and control means being mounted on said driver's seat for pivotal movement therewith about said vertical axis.
Claim 2
Dependent Claim 246 words
