Biasing cradle for refuse vehicle
A cradle and guide system for a refuse vehicle has at least one track member mounted on a bumper of a refuse vehicle. The at least one track member is able to deflect horizontally to compensate for misalignment. At least one guide member is mounted to a front loading fork of the refuse vehicle. The at least one guide member contacts the at least one track member to limit horizontal movement of the front loading fork with respect to the refuse vehicle during misalignment. The at least one track member returns to its original position to align the front loading forks.
1. A cradle system for a refuse vehicle defining a forward direction of travel on a ground surface, the cradle system comprising:
at least one track fastened in a fixed position on a bumper of the refuse vehicle, the at least one track comprising:
a stationary plate, and
a deflectable plate, at least a portion of the deflectable plate and the stationary plate extending outward from the bumper in the forward direction;
at least one guide mounted on a front-loading fork of the refuse vehicle, the at least one guide configured to engage the deflectable plate during misalignment of a front-loading fork relative to the refuse vehicle in a direction transverse to the forward direction of travel; and
at least one spring secured to the stationary plate and aligned with the deflectable plate, the at least one spring configured to bias the deflectable plate against the at least one guide in the transverse direction.
2. The cradle system of claim 1 , wherein the deflectable plate has a vertical leg and an angled end that is continuous with the vertical leg.
3. The cradle system of claim 2 , wherein the at least one spring is secured proximate to an intersection of the vertical leg and the angled end.
4. The cradle system of claim 1 , wherein the at least one track has a length extending transverse to the ground surface.
5. The cradle system of claim 4 , wherein the at least one spring is angled with respect to the length of the at least one track.
6. The cradle system of claim 4 , wherein the at least one spring is parallel with respect to the length of the at least one track.
7. The cradle system of claim 1 , further comprising a wear pad on one of the at least one track or guide.
8. The cradle system of claim 1 , wherein the at least one spring enables a deflection and return of the deflectable plate.
9. The cradle system of claim 1 , wherein the deflectable plate of the at least one track is configured to deflect horizontally to compensate for the misalignment of the front-loading fork relative to the refuse vehicle.
10. The cradle system of claim 1 , wherein the at least one track is configured to return to an undeflected position to align the front-loading fork.
11. The cradle system of claim 1 , wherein the at least one guide is coupled to the front-loading fork and held fixed relative to the front-loading fork.
12. The cradle system of claim 1 , wherein the at least one spring is positioned between the deflectable plate and the stationary plate.
13. The cradle system of claim 1 , further comprising a pivot secured at a distal end of the deflectable plate, the pivot configured to enable the at least one track to deflect horizontally.
14. The cradle system of claim 1 , wherein the at least one spring comprises a movable rod secured to the deflectable plate, and a cylinder secured to the stationary plate.
15. The cradle system of claim 1 , wherein the stationary plate and the deflectable are parallel with respect to each other.
16. The cradle system of claim 1 , comprising a pair of springs secured to the stationary plate and aligned with the deflectable plate, wherein the pair of springs is positioned between the stationary plate and the deflectable plate.
17. A refuse vehicle defining a forward direction of travel on a ground surface, the refuse vehicle comprising:
a vehicle chassis including a cab;
a container coupled within a rear portion of the chassis;
front-loading forks coupled with the refuse vehicle for dumping intermediate containers into the container on the rear portion of the chassis;
at least one track fastened in a fixed position on a bumper of the refuse vehicle, the at least one track comprising:
a stationary plate, and
a deflectable plate, at least a portion of the deflectable plate and the stationary plate extending outward from the bumper in the forward direction;
at least one guide mounted on a front-loading fork of the refuse vehicle, the at least one guide configured to engage the deflectable plate during misalignment of a front-loading fork relative to the refuse vehicle in a direction transverse to the forward direction of travel; and
at least one spring secured to the stationary plate and aligned with the deflectable plate, the at least one spring configured to bias the deflectable plate against the at least one guide in the transverse direction.
18. The refuse vehicle of claim 17 , wherein the at least one track has a length extending transverse to the ground surface.
19. The refuse vehicle of claim 18 , wherein the at least one spring is angled with respect to the length of the at least one track.
20. The refuse vehicle of claim 18 , wherein the at least one spring is parallel with respect to the length of the at least one track.
21. The refuse vehicle of claim 17 , wherein the at least one spring enables a deflection and return of the deflectable plate.
22. The refuse vehicle of claim 17 , wherein the deflectable plate is configured to deflect horizontally to compensate for the misalignment of the front-loading fork relative to the refuse vehicle.
23. The refuse vehicle of claim 17 , wherein the at least one guide is coupled to the front-loading fork and held fixed relative to the front-loading fork.
