PROBLEM TO BE SOLVED: To provide a running operation device provided with high operability by disposing one running operation device near a load hook which is a load suspension tool without needing two running operation devices, and capable of enlarging the vertical moving stroke of the load hook or the like, improving hitching and handling performance, and running and operating an electrically-driven hoist even from a position away from the load hook.SOLUTION: A running operation device includes: a cylindrical casing having a gripping part 36 disposed in an outer peripheral part to grip the device by hand, the operation part of a hoist operation switch and a winding-down operation switch disposed at a position allowing the operation part to be operated by the fingers of the hand gripping the gripping part 36; a signal generation circuit, a wireless transmission unit for converting a winding-up and down signal into a wireless signal to transmit it, and a battery storage part for storing a battery in the cylindrical casing; a load suspension tool connection mechanism for detachably connecting the upper end part of a load suspension tool at the lower end part of the cylindrical casing; and a load suspension tool/cylindrical casing connection mechanism for detachably connecting the upper end part of the load suspension tool or the cylindrical casing at the lower end thereof.SELECTED DRAWING: Figure 2 |
