Abstract

Radial conveyors and undercarriages therefor are disclosed. Some embodiments include a wheel assembly with transport and operational configurations. In some embodiments, a wheel of the wheel assembly is selectively aligned with a tail pivot of the radial conveyor.

First claim

The invention claimed is:

1. A radial conveyor having a transport configuration and an operating configuration, the radial conveyor configured to pivot about a tail pivot axis along a radial travel path in the operating configuration, the radial conveyor configured to travel along a transport travel direction in the transport configuration, the radial conveyor comprising:
an undercarriage frame;
a first pivot arm, the first pivot arm being pivotally coupled to a first side of said undercarriage frame for pivoting about a first vertical axis;
a first wheel support assembly operably supported by said first pivot arm, said wheel support assembly comprising:
a first rocking member, said first rocking member being pivotally coupled to said pivot arm for pivoting about a first horizontal axis;
a second rocking member, said second rocking member being pivotally coupled to said first rocking member for pivoting about a second horizontal axis;
a first wheel supported by said second rocking member;
a second wheel supported by said second rocking member;
a pivoting axle support, said pivoting axle support being pivotally coupled to said first rocking member for pivoting about a second vertical axis; and
a third wheel rollingly supported on said pivoting axle support.

2. The radial conveyor of claim 1 , wherein said pivoting axle support is pivotable between a first and second position of the pivoting axle support, wherein said pivoting axle support is in its first position in the transport configuration, and wherein said pivoting axle support is in its second position in the operating configuration.

3. The radial conveyor of claim 2 , wherein in said operating configuration, an axis of rotation of said third wheel is aligned with said tail pivot axis.

4. The radial conveyor of claim 3 , wherein in said transport configuration, an axis of rotation of said third wheel is generally perpendicular to the transport direction.

5. The radial conveyor of claim 3 , further comprising:
a first locking mechanism configured to alternately lock said pivoting axle support in said first and second positions of said pivoting axle support.

6. The radial conveyor of claim 2 , further comprising:
a first locking mechanism configured to alternately lock said pivoting axle support in said first and second positions of said pivoting axle support.

7. The radial conveyor of claim 1 , wherein said first horizontal axis is disposed outboard of said second horizontal axis.

8. The radial conveyor of claim 1 , wherein said second vertical axis is disposed outboard of said second vertical axis.

9. The radial conveyor of claim 1 , wherein said first pivot arm extends generally outwardly from said undercarriage frame in the operating configuration, and wherein said pivot arm is generally aligned with said transport travel direction in the transport configuration.

10. The radial conveyor of claim 1 , further comprising:
a second pivot arm, the second pivot arm being pivotally coupled to a second side of said undercarriage frame; and
a second wheel support assembly operably supported by said second pivot arm.

11. A method of reconfiguring a radial conveyor having first, second, and third wheels supported on a pivot arm between a transport configuration in which the radial conveyor is transported along a linear transport travel direction and an operating configuration in which the radial conveyor travels along a radial travel direction about a tail pivot, the method comprising:
using the pivot arm, aligning an axis of a first one of said first, second and third wheels with the tail pivot;
aligning an axis of a second one of the said first, second and third wheels with the tail pivot; and
using a first locking device, locking the pivot arm in position with respect to the tail pivot.

12. The method of claim 11 , further comprising:
using a second locking device, locking the second one of the first, second and third wheels in a position with respect to the tail pivot.

13. A radial conveyor having a transport configuration and an operating configuration, the radial conveyor configured to pivot about a tail pivot axis along a radial travel path in the operating configuration, the radial conveyor configured to travel along a transport travel direction in the transport configuration, the radial conveyor comprising:
an undercarriage frame;
a first pivot arm, the first pivot arm being pivotally coupled to a first side of said undercarriage frame for pivoting about a first vertical axis;
a first wheel support assembly operably supported by said first pivot arm, said wheel support assembly comprising:
a first rocking member, said first rocking member being pivotally coupled to said pivot arm for pivoting about a first horizontal axis;
a first wheel supported by said first rocking member;
a second rocking member, said second rocking member being pivotally coupled to said first rocking member for pivoting about a second horizontal axis;
a second wheel supported by said second rocking member;
a pivoting axle support, said pivoting axle support being pivotally coupled to said second rocking member for pivoting about a second vertical axis; and
a third wheel rollingly supported on said pivoting axle support.

14. The radial conveyor of claim 13 , wherein said pivoting axle support is pivotable between a first and second position of the pivoting axle support, wherein said pivoting axle support is in its first position in the transport configuration, and wherein said pivoting axle support is in its second position in the operating configuration.

15. The radial conveyor of claim 14 , wherein in said operating configuration, an axis of rotation of said third wheel is aligned with said tail pivot axis.

16. The radial conveyor of claim 15 , wherein in said transport configuration, an axis of rotation of said third wheel is generally perpendicular to the transport direction.

17. The radial conveyor of claim 15 , further comprising:
a first locking mechanism configured to alternately lock said pivoting axle support in said first and second positions of said pivoting axle support.

18. The radial conveyor of claim 14 , further comprising:
a first locking mechanism configured to alternately lock said pivoting axle support in said first and second positions of said pivoting axle support.

19. The radial conveyor of claim 13 , wherein said first horizontal axis is disposed outboard of said second horizontal axis.

20. The radial conveyor of claim 13 , wherein said second vertical axis is disposed outboard of said second vertical axis.

21. The radial conveyor of claim 13 , wherein said first pivot arm extends generally outwardly from said undercarriage frame in the operating configuration, and wherein said pivot arm is generally aligned with said transport travel direction in the transport configuration.

22. The radial conveyor of claim 13 , further comprising:
a second pivot arm, the second pivot arm being pivotally coupled to a second side of said undercarriage frame; and
a second wheel support assembly operably supported by said second pivot arm.
