Abstract

A service access walkway for a rotary mixer machine is provided. The service access walkway includes a first walkway section and a second walkway section pivotally coupled to the first walkway section by at least one hinge. The second walkway section is configured to pivot between a closed position and an open position. The service access walkway further includes a magnetic assembly configured to magnetically engage the second walkway section with the rotary mixer machine when the second walkway section is in the closed position.

First claim

What is claimed is:

1. A service access walkway for a rotary mixer machine, the service access walkway comprising:
a first walkway section;
a second walkway section pivotally coupled to the first walkway section by at least one hinge and configured to pivot between a closed position and an open position, the second walkway including:
a midsection;
a first side portion laterally extending away from the midsection;
a second side portion laterally extending away from the midsection in a same direction as the first side portion; and
a top surface and a bottom surface extending between the first side portion and the second side portion; and

a magnetic assembly configured to magnetically engage the second walkway section with the rotary mixer machine when the second walkway section is in the closed position.

2. The service access walkway of claim 1 , wherein the magnetic assembly is configured to be disposed between a frame of the rotary mixer machine and the second walkway section to magnetically engage the bottom surface of the second walkway section with the frame when the second walkway section is in the closed position.

3. The service access walkway of claim 1 , wherein the first walkway section is coupled to the midsection of the second walkway section by the at least one hinge.

4. The service access walkway of claim 1 , wherein the magnetic assembly includes:
a first magnet configured to be positioned on a first portion of a frame of the rotary mixer machine underneath the first side portion of the second walkway section; and
a second magnet configured to be positioned on a second portion of the frame underneath the second side portion of the second walkway section to magnetically engage the bottom surface of the second walkway section with the frame when the second walkway section is in the closed position.

5. The service access walkway of claim 1 , wherein the second walkway section is configured to pivot by 180 degrees from the closed position to lay flat atop the first walkway section, when the second walkway section is in the open position.

6. The service access walkway of claim 1 , wherein the second walkway section has a treaded top surface and a treaded bottom surface.

7. A rotary mixer machine comprising:
a frame;
one or more serviceable components disposed on the frame; and
a service access walkway to facilitate walkway access to the one or more serviceable components, the service access walkway including:
a first walkway section detachably coupled to the frame;

a second walkway section pivotally coupled to the first walkway section by at least one hinge, the second walkway section being in a closed position to overlay at least one serviceable component of the one or more serviceable components, wherein the second walkway section is pivotable about the at least one hinge to a series of open positions for providing access to the at least one serviceable component, the second walkway including:
a midsection;
a first side portion laterally extending away from the midsection;
a second side portion laterally extending away from the midsection in a same direction as the first side portion; and
a top surface and a bottom surface extending between the first side portion and the second side portion; and

a magnetic assembly disposed between the frame and the second walkway section, the magnetic assembly being configured to magnetically engage the second walkway section with the frame when the second walkway section is in the closed position.

8. The rotary mixer machine of claim 7 , wherein the first walkway section is coupled to the midsection of the second walkway section by the at least one hinge.

9. The rotary mixer machine of claim 7 , wherein the magnetic assembly includes a first magnet positioned on a first portion of the frame underneath the first side portion of the second walkway section and a second magnet positioned on the frame underneath the second side portion of the second walkway section to magnetically engage the bottom surface of the second walkway section with the frame when the second walkway section is in the closed position.

10. The rotary mixer machine of claim 7 , wherein the series of open positions include a first open position where the second walkway section pivots by 180 degrees from the closed position and lays flat atop the first walkway section.

11. The rotary mixer machine of claim 7 , wherein the at least one serviceable component includes an engine oil cap.

12. The rotary mixer machine of claim 7 , wherein the second walkway section has a treaded top surface and a treaded bottom surface.

13. A rotary mixer machine comprising:
a frame;
one or more serviceable components disposed on the frame; and
a service access walkway to facilitate walkway access to the one or more serviceable components, the service access walkway including:
a first walkway section detachably coupled to the frame;

a second walkway section pivotally coupled to the first walkway section by at least one hinge, the second walkway section being in a closed position to overlay at least one serviceable component of the one or more serviceable components, wherein the second walkway section is pivotable about the at least one hinge to an open position such that the second walkway section lays flat atop the first walkway section for providing access to the at least one serviceable component, the second walkway including:
a midsection;
a first side portion laterally extending away from the midsection;
a second side portion laterally extending away from the midsection in a same direction as the first side portion; and
a top surface and a bottom surface extending between the first side portion and the second side portion; and

a magnetic assembly disposed between the frame and the second walkway section, the magnetic assembly being configured to magnetically engage the second walkway section with the frame when the second walkway section is in the closed position.

14. The rotary mixer machine of claim 13 , wherein the first walkway section is coupled to the midsection of the second walkway section by the at least one hinge.

15. The rotary mixer machine of claim 13 , wherein the magnetic assembly includes a first magnet positioned on a first portion of the frame underneath the first side portion of the second walkway section and a second magnet positioned on a second portion of the frame underneath the second side portion of the second walkway section to magnetically engage the bottom surface of the second walkway section with the frame.

16. The rotary mixer machine of claim 13 , wherein the at least one serviceable component includes an engine oil cap.

17. The rotary mixer machine of claim 13 , wherein the second walkway section has a treaded top surface and a treaded bottom surface.
