The present invention provides a traveling operation device for a crawler-type overhead working truck, which can perform all traveling operations including an enable switch operation in addition to traveling operations such as advancing, retreating, turning, stopping and the like of the crawler-type overhead working truck by a single hand. An enable switch (22) and a change-over switch (24) are arranged on an operation rod main body (21) of an operation rod (20) which is operated by an operator during driving, and the enable switch (22) and the change-over switch (24) can be operated by the same finger holding the operation rod main body (21), so that the enable switch (22) and the change-over switch (24) can be operated by a single hand. Furthermore, when the controller (70) receives a switching command signal accompanying the operation of the switching switch (24) from a normal travel control state in which the overhead working truck (1) is moved forward, backward, stopped, and turned in accordance with the tilting of the operating lever (20) in the front-rear direction and the tilting of the operating lever (20) in the left-right direction, the controller (70) stops the normal travel control, and the controller (70) stops the normal travel control when the controller (70) receives the switching command signal accompanying the operation of the switching switch (24). In the spin-turn control, the left motor (60a) and the right motor (60b) are rotated in opposite directions to turn the overhead working truck (1) at the location.

    本发明提供一种履带式高空作业车的行驶操作装置,除了能用单手进行履带式高空作业车的前进、后退、转弯、停止等行驶操作以外,还能进行包括使能开关操作的所有行驶操作。在构成行驶时操作者操作的操作杆(20)的操作杆主体(21)上,在用把持该操作杆主体(21)的相同的手指能够操作的位置上设置使能开关(22)和切换开关(24),使它们全部能够用单手操作。并且,从根据操作杆(20)前后方向的倾动和左右方向的倾动而使高空作业车(1)前进、后退、停止、转弯的通常行驶控制的状态,若控制器(70)接收到伴随切换开关(24)的操作的切换指令信号,则控制器(70)停止通常行驶控制,转移到使左侧电动机(60a)和右侧电动机(60b)向相互相反方向旋转从而使高空作业车(1)在该场所转弯的自旋转弯控制。
