Abstract:

To provide a working machine in which the strength of the lift arm and the main beam for bearing a load of an attachment and a compressive load of a lift cylinder is increased by means of a stand, so as to prevent their deformation, while stable workability can be maintained.

This working machine includes: the lift cylinder 26 which is attached together with a connecting member to a hitch 21 installed in a machine body; the main beam 23 which has one end of the lift cylinder 26 supported at a supporting position d; the lift arm 24 which has the main beam 23 provided in the midway portion, and which has an attachment 25 attached to a leading end via an attachment member; and the stand 31, the base end of which is pivoted on the lift arm 24 and the other end of which can be locked in the locking position c of the main beam 23. The other end of the stand 31 is locked to the main beam 23 so that the main beam 23, the lift arm 24 and the stand 31 can form an approximately triangular shape in a side view.
