Loader cab
Disclosed embodiments include power machine cabs, cab subassemblies, corresponding power machines such as skids steer loaders, and methods of assembling cabs and power machines. Some exemplary disclosed embodiments include features aiding in the manufacture of the cabs for power machines, features which allow the cabs to be configurable for different customer preferences or needs, and features which allow detection of tampering with the cab such that the power machine can be controlled accordingly.
1. A cab assembly for a power machine, the cab assembly comprising:
a cab frame defining an operator compartment;
a pivot attachment on a rear of the cab frame and configured to pivotally attach the cab assembly to a frame of the power machine such that the cab assembly can be pivoted about the pivot attachment relative to the frame of the power machine;
a cab mount coupled to a front surface of the cab frame outside of the operator compartment and configured to releasably secure the cab frame to the frame of the power machine to prevent the cab assembly from being pivoted about the pivot attachment, wherein the cab mount extends from the front surface of the cab frame in a direction which is angled relative to a horizontal direction when the cab frame is in a lowered position in which the cab mount can secure the cab frame to the frame of the power machine.
2. The cab assembly of claim 1 , wherein the cab mount extends orthogonally from the front surface of the cab frame.
3. The cab assembly of claim 1 , wherein the direction in which the cab mount extends is angled relative to the horizontal direction by at least 35 degrees.
4. The cab assembly of claim 2 , wherein the cab mount includes an aperture configured to receive a threaded stud of a cab mounting structure secured to the frame of the power machine.
5. The cab assembly of claim 4 , wherein the cab mount includes an anti-rotation feature configured to prevent rotation of the cab mounting structure relative to the cab mount.
6. The cab assembly of claim 5 , wherein the anti-rotation feature comprises a pair of ribs configured to receive therebetween an anti-rotation member of the cab mounting structure to prevent rotation of the cab mounting structure relative to the cab mount.
7. The cab assembly of claim 1 , wherein the cab mount comprises a single piece casting.
8. The cab assembly of claim 7 , wherein the single piece casting includes a first mounting surface configured to be mounted to the front surface of the cab frame and a second mounting surface configured to be mounted to a side surface of the cab frame.
9. A cab mount configured to be secured to a cab frame of a power machine to secure the cab frame to a power machine frame and prevent rotation of the cab frame relative to the power machine frame, the cab mount comprising:
a single piece casting, the single piece casting comprising:
a base portion providing a first mounting surface configured to be secured to a front surface of the cab frame and a second mounting surface configured to be secured to a side surface of the cab frame; and
a mounting portion extending from the base portion and including an aperture configured to receive a threaded stud of a cab mounting structure secured to the frame of the power machine.
10. The cab mount of claim 9 , wherein the mounting portion of the single piece casting extends generally orthogonally from the base portion of the single piece casting.
11. The cab mount of claim 9 , wherein the single piece casting is configured to be secured to the cab frame such that a direction in which the mounting portion of the cab mount extends from the cab frame is angled relative to a horizontal direction by at least 35 degrees.
12. The cab mount of claim 9 , wherein the single piece casting includes an anti-rotation feature configured to prevent rotation of the cab mounting structure relative to the cab mount.
13. The cab mount of claim 12 , wherein the anti-rotation feature comprises a pair of ribs formed in the base portion and configured to receive therebetween an anti-rotation member of the cab mounting structure to prevent rotation of the cab mounting structure relative to the cab mount.
