STEERING DEVICE FOR CONSTRUCTION MACHINE

摘要

A tilt-up mechanism (25) for tilting up an upper column (16) of a steering column (13) from a drive position to a tilt-up position is configured independently from a tilt angle adjusting mechanism (33) and a column length adjusting mechanism (37). When an operator who is to get on/off an operator's seat (9) steps on and operates a pedal (44) of the tilt-up mechanism (25), an engaged state of a lock pin (40) with respect to a tilt-up member (26) is disengaged. The tilt-up member (26) is rotated around a support shaft (31), (32) by a spring force of a tilt-up spring (47), whereby the upper column (16) is tilted up together with a steering wheel (12) in a direction (A) away from the operator's seat (9). At this time, the tilt angle and the column length can be held at positions adjusted in advance.
