PROBLEM TO BE SOLVED: To provide a long object lifting and lowering device which, firstly, can simply and reliably prevent the runout of a lower end of a long object, and secondly, allows for reduction in the longitudinal direction-length and width of a lifting/lowering arm, thereby capable of being made compact as a whole.SOLUTION: The long object lifting and lowering device comprises a wire rope 11, an upper arm 12, a wire receiving band 13, a lower arm 14, a winch 15, a guide rope 16 and a lifting/lowering arm 17. The lower arm 14 includes: a lower arm body with one end side fixed to a height part capable of carrying out the ground work of a strut; an opening/closing arm 14f having a base end connected to the lower arm body in a turning manner, and sandwiching the lower end of a long object 3 such as a fire extinguishing hose between the lower arm body and itself when closed; and locking means 14 g for locking the opening/closing arm 14f in the lower arm body when the opening/closing arm 14f is closed with respect to the lower arm body.SELECTED DRAWING: Figure 1
