<P>PROBLEM TO BE SOLVED: To facilitate loading and unloading work of a gas cylinder to a machine by stably supporting the gas cylinder at the comparatively low position of the machine, and at a position where visibility of an operator is not disturbed. <P>SOLUTION: The support device 3 of the gas cylinder 25 includes: a fixed frame 30 fixed to a machine body side; a movable frame 31 which can be operated in a rocking manner; and a fixed metal fitting 6 mounted on the movable frame 31. One end of the movable frame 31 is constituted to be connected/disconnected to/from the fixed frame 30, and the other side of the movable frame 31 is pivotally attached to the machine body side at a side lower than a connection point to the fixed frame 30 and around a horizontal direction axis x in a direction which crosses the central axis of the gas cylinder 25 which is loaded in an attitude of falling sideways. Switching between a loading attitude in the attitude of falling sideways and a descent attitude in which it is taken down on the ground in a vertical attitude, can be performed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
