Abstract
A ladder assembly for a work vehicle is disclosed. The ladder assembly may generally include a ladder having a first side rail, a second side rail and first and second rungs extending between the first and second side rails. The ladder may be supported on the work vehicle at a first pivot point and a second pivot point. The ladder may also include a first linkage and a second linkage. The first linkage may be coupled between the first rung and the first pivot point and the second linkage may be coupled between the second rung and the second pivot point. In addition, the ladder may be configured to pivot about the first and second pivot points between a first position and a second position.
Claims19
A work vehicle comprising:
- a fuel tank comprising at least one recessed channel;
- a ladder assembly pivotally supported relative to the fuel tank, the ladder assembly comprising:
- a ladder including a first side rail, a second side rail, and first and second rungs extending between the first and second side rails, the ladder being supported on the work vehicle at a first pivot point and a second pivot point, the ladder further comprising a first linkage and a second linkage, the first linkage being coupled between the first rung and the first pivot point, the second linkage being coupled between the second rung and the second pivot point, wherein the ladder is configured to pivot about the first and second pivot points between a first position and a second position;
- and
- a biasing mechanism coupled to the first linkage or to the second linkage, wherein the biasing mechanism is configured to bias the ladder toward the first position when a respective linkage is above a horizontal orientation and toward the second position when the respective linkage is below the horizontal orientation, and the at least one recessed channel is configured to at least partially receive the first or second rung.
A work vehicle comprising:
- a fuel tank;
- a ladder assembly pivotally supported relative to the fuel tank, the ladder assembly comprising:
- a ladder including a first side rail, a second side rail, and first and second rungs extending between the first and second side rails, wherein the ladder is supported relative to the fuel tank at a first pivot point and a second pivot point, the ladder comprises a first linkage and a second linkage, the first linkage is coupled between the first rung and the first pivot point, the second linkage is coupled between the second rung and the second pivot point, and the ladder is configured to pivot about the first and second pivot points relative to the fuel tank between a first position and a second position;
- and
- a biasing mechanism coupled to a respective linkage of the first linkage or the second linkage, wherein the biasing mechanism is configured to bias the ladder toward the first position when the respective linkage is above a horizontal orientation and toward the second position when the respective linkage is below the horizontal orientation,
- wherein the fuel tank comprises at least one recessed channel configured to receive at least a portion of the ladder.
A work vehicle comprising:
- a fuel tank comprising at least one recessed channel;
- a ladder assembly pivotally supported relative to the fuel tank, the ladder assembly comprising:
- a ladder including a first side rail, a second side rail, and first and second rungs extending between the first and second side rails, wherein the ladder is supported relative to the fuel tank at a first pivot point and a second pivot point, the ladder comprises a first linkage and a second linkage, the first linkage is coupled between the first rung and the first pivot point, the second linkage and coupled between the second rung and the second pivot point, the ladder is configured to pivot about the first and second pivot points relative to the fuel tank between a first position and a second position, and the at least one recessed channel is configured to at least partially receive the first or second rung.
