Document Type and Number:
Japanese Patent JP2016075089
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ladder mechanism that may be stored in a narrow space between a lower machinery and an upper work body, and also be expanded compactly.SOLUTION: The ladder mechanism is mounted on a rough terrain crane 10. The ladder mechanism includes a ladder 13 and a ladder driving device 14. The ladder driving device 14 has an arm support shaft 49 and a ladder support shaft 42. The arm support shaft 49 is disposed along a longer-side direction of the lower machinery 11, and rotatably supports a swing arm 43. The ladder support shaft 42 is disposed along a direction orthogonal to the arm support shaft 49, and supports the ladder 13. The ladder 13 rotates around the arm support shaft 49 and is extended sideways of the lower machinery 11, and rotates around the ladder support shaft 42 to be leaned against the lower machinery 11.SELECTED DRAWING: Figure 4
