Abstract
A lift machine includes a chassis, a boom assembly, an axle, and an actuator. The chassis defines a longitudinal center axis. The chassis has an axle housing with (a) a first sidewall defining a first notch and (b) a second sidewall opposite the first sidewall and defining a second notch. The boom assembly is pivotable relative to the chassis. The axle is pivotally coupled to the axle housing. The axle is configured to pivot about the longitudinal center axis relative to the axle housing such that portions of the axle move within the first notch and the second notch. The actuator is positioned on a first lateral side of the longitudinal center axis. The actuator is positioned to facilitate selective oscillation of the axle.

A lift machine comprising:
- a chassis defining a longitudinal center axis, the chassis having an axle housing with (a) a first sidewall defining a first notch and (b) a second sidewall opposite the first sidewall and defining a second notch;
- a boom assembly pivotable relative to the chassis;
- an axle pivotally coupled to the axle housing, the axle configured to pivot about the longitudinal center axis relative to the axle housing such that portions of the axle move within the first notch and the second notch;
- and
- an actuator positioned on a first lateral side of the longitudinal center axis, wherein the actuator is positioned to facilitate selective oscillation of the axle.
A machine comprising:
- an axle housing including:
- a first sidewall defining a first notch;
- and
- a second sidewall opposite the first sidewall, the second sidewall defining a second notch;
- an axle pivotably coupled to the axle housing;
- a first actuator coupled to the first sidewall and pinned to a first point on the axle;
- and
- a second actuator coupled to the second sidewall and pinned to a second point on the axle;
- wherein, as the axle pivots, the axle moves relative to the axle housing and within the first notch and the second notch.
A machine comprising:
- a housing including:
- a first sidewall defining a first notch;
- and
- a second sidewall opposite the first sidewall, the second sidewall defining a second notch;
- an axle pivotable relative to the housing;
- and
- an actuator coupled to the first sidewall and pinned to a point on the axle;
- wherein, as the axle pivots, the axle moves relative to the housing and at least partially within the first notch and the second notch.
