Abstract
A chassis for a lift device includes a base, an arm coupled to the base and configured to support a tractive element, and a plate extending from the arm at an upward angle. The arm includes a steering actuator interface configured to support an end of a steering actuator for the tractive element. The plate is configured to extend past the steering actuator.
Claims15
A chassis for a lift device, the chassis comprising:
- a base defining an arm interface;
- an arm pivotably coupled to the arm interface of the base and configured to support a tractive element, the arm including a steering actuator interface configured to support an end of a steering actuator for the tractive element;
- and
- a plate extending from the arm at an upward angle, the plate configured to be positioned beneath and extend past the steering actuator;
- wherein the arm has a longitudinal portion coupled to the base and a lateral portion extending from the longitudinal portion that supports the tractive element and from which the plate extends;
- wherein the lateral portion of the arm has a first surface facing the base and a second surface facing away from the base;
- wherein the steering actuator interface is positioned along the second surface;
- wherein the base defines a first pivot actuator interface and the arm defines a second pivot actuator interface positioned along the first surface;
- and
- wherein the first pivot actuator interface of the base and the second pivot actuator interface of the lateral portion are configured to support ends of a pivot actuator.
