Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a construction elevator support dismantling crane that can dismantle construction elevator supports safely and provide a dismantling method. SOLUTION: A portal frame 3 is erected on a carrier 2 elevated being supported by supports 1, and a fixed rail 4 is fixedly provided at the upper part of the portal frame 3. A moving rail 6 is provided to traverse in the portal frame 3 being supported by the fixed frame 4, and a motor-driven chain block 8 is provided to traverse in the portal frame 3 being supported by the moving rail 6. The moving rail 6 is slided, or the motor-driven chain block 8 is slided to take in the supports 1 without turning a crane.
