A telescopic boom extension device includes a cylinder-boom coupling mechanism, an inter-boom fixing mechanism, and a driving mechanism that drives the foregoing two. The driving mechanism has a hydraulic supply part and a drive source generation part. The hydraulic supply part includes an AOH and is provided at a cylinder tube of a telescopic boom. 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 and supplies compressed air to the AOH. The air hose is wound around a hose reel in an unrollable manner.
