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.

Claims (55)

1. 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.

2. The chassis of claim 1 , further comprising the tractive element and the steering actuator.

3. The chassis of claim 1 , wherein the lateral portion extends perpendicularly from the longitudinal portion.

4. The chassis of claim 1 , wherein the lateral portion extends at an obtuse angle from the longitudinal portion.

5. The chassis of claim 1 , further comprising:

the pivot actuator; and

a pressure sensor assembly including:

a first mount positioned along the pivot actuator;

a second mount positioned along the pivot actuator and spaced from the first mount; and

a cover extending along the pivot actuator and coupled to the first mount and the second mount;

wherein at least one of the first mount or the second mount is configured to facilitate coupling a pressure sensor to the pivot actuator.

6. The chassis of claim 1 , wherein the arm is a first arm, further comprising a second arm coupled to a side of the base opposite the first arm, wherein the first arm and the second arm have a different shape or structure.

7. The chassis of claim 1 , wherein at least one of:

a portion of a bottom surface of the arm is angled; or

the plate is continuous with the portion of the bottom surface that is angled.

8. A chassis for a lift device, the chassis comprising:

a base;

an arm coupled to 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 extend past the steering actuator;

wherein a portion of a bottom surface of the arm is angled; and

wherein the plate is continuous with the portion of the bottom surface that is angled.

9. A chassis for a lift device, the chassis comprising:

a base (i) defining an interior chamber and an aperture that facilitates passing at least one of hosing or wiring through a wall of the base into the interior chamber and (ii) [has]] having a tab positioned proximate the aperture and that extends from the wall, wherein the tab facilitates securing the at least one of the hosing or the wiring thereto using a retainer;

an arm coupled to 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 extend past the steering actuator.

10. The chassis of claim 9 , wherein the tab defines notches at opposing ends thereof that at least partially prevent the retainer from sliding off of the tab.

11. A chassis for a lift device, the chassis comprising:

a base (i) defining an arm interface, an interior chamber, and an aperture that facilitates passing at least one of hosing or wiring through a wall of the base into the interior chamber and (ii) having a tab positioned proximate the aperture and that extends from the wall, and wherein the tab facilitates securing the at least one of the hosing or the wiring thereto using a retainer;

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, the plate configured to be positioned beneath and extend past the steering actuator.

12. The chassis of claim 11 , wherein the arm has a first portion coupled to the base and a second portion extending from the first portion that supports the tractive element and from which the plate extends.

13. The chassis of claim 11 , wherein a portion of a bottom surface of the arm is angled.

14. 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, the plate configured to be positioned beneath and extend past the steering actuator;

wherein the arm has a first portion coupled to the base and a second portion extending from the first portion that supports the tractive element and from which the plate extends;

wherein the second 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 second portion are configured to support ends of a pivot actuator.

15. 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, the plate configured to be positioned beneath and extend past the steering actuator;

wherein a portion of a bottom surface of the arm is angled; and

wherein the plate is continuous with the portion of the bottom surface that is angled.
