Materials handling vehicle
First Claim
1. A materials handling vehicle comprising:
- a frame comprising a longitudinal centerline and an operator compartment;
first and second front wheels coupled to said frame;
a rear steer wheel assembly coupled to said frame and comprising a substantially vertical steer axle, said steer axle being laterally offset from said longitudinal centerline;
mast apparatus coupled to said frame and including a pair of forks;
a battery associated with said frame and having a center of gravity, said battery being positioned such that said battery center of gravity is laterally offset from said longitudinal center line;
wherein a stability triangle for said vehicle is defined by a first point at said first front wheel, a second point at said second front wheel and a third point defined by said substantially vertical steer axle at said rear steer wheel assembly, said stability triangle defining a scalene triangle; and
wherein said third point of said stability triangle is laterally offset from said longitudinal center line toward a first side of said frame and located nearer to said longitudinal centerline than to said first side of said frame.

Abstract
A materials handling vehicle is provided comprising a frame including a longitudinal centerline and an operator compartment; first and second front wheels coupled to the frame; a rear steer wheel assembly coupled to the frame; mast apparatus coupled to the frame and including a pair of forks; and a battery associated with the frame and having a center of gravity. The battery is preferably positioned such that the battery center of gravity is laterally offset from the longitudinal center line. A stability triangle for the vehicle is defined by a first point at the first front wheel, a second point at the second front wheel and a third point at the rear steer wheel assembly. Preferably, the stability triangle defines a scalene triangle.
