項１記載の重量物等の移動装置。[Scope of Claim for Utility Model Registration] (1) A plurality of hydraulic jacks are fixed in a straight line at intervals, and each piston rod of the fixed hydraulic jacks is provided with a clamping mechanism for attaching and detaching a tension member linked to a heavy object. Furthermore, in the hydraulic jack, the oil supply ports on the side that shortens the stroke of the piston rod are connected to each other with a hydraulic hose, and conversely, a hydraulic pump that feeds hydraulic oil to the oil supply port on the side that extends the piston rod is connected via a directional control valve. Features: A device for moving heavy objects. (2) The tension member attachment/detachment clamp mechanism automatically chucks the tension member when the piston rod operates to extend the stroke, and automatically releases the tension member when the piston rod operates to shorten the stroke. 2. The apparatus for moving heavy objects, etc. according to claim 1, characterized in that it is a wedge-shaped attachment/detachment clamp mechanism configured as follows.
