A telescopic boom extension device (10) includes a cylinder-boom coupling mechanism (15), an inter-boom fixing mechanism (16), and a driving mechanism (17) that drives the foregoing two. The driving mechanism has a hydraulic supply part (18) and a drive source generation part (19). The hydraulic supply part includes an AOH and is provided at a cylinder tube of a telescopic boom (13). The hydraulic supply part supplies operating oil selectively to actuators driving a B pin and a C pin. The drive source generation part includes an air hose (57) and supplies compressed air to the AOH. The air hose is wound around a hose reel in an unrollable manner.
