PROBLEM TO BE SOLVED: To provide a passenger loading bridge capable of properly detecting a fact that drive wheels of a travel device used for extension movement and/or horizontal movement of a tunnel part come close to an obstacle.SOLUTION: A passenger loading bridge comprises: a tunnel part which is fitted in a nested box-state, and which can relatively move in a cross direction and which can be extended; a drive column which is used for vertical movement of the tunnel part; and a travel device 13 which is used for extension movement and/or horizontal movement of the tunnel part. The travel device comprises: a support frame 17 for supporting the drive column; a driver 16A mounted on the support frame; drive wheels 14A, 14B driven by the driver; and a detection part for detecting a fact that the drive wheels come close to an obstacle. The detection part 39A comprises: a holding member 33 which is connected to the support frame; a flexible member 30 which is held to the holding member, and stretched in the surrounding of the drive wheels; a tensioner 31 for applying tension force to the flexible member; and a switch 32 which is switched based on a change of the tension force applied to the flexible member.SELECTED DRAWING: Figure 2
【課題】トンネル部の伸縮移動および/または水平動に用いる走行装置の駆動輪が障害物に接近したことを適切に検出し得る旅客搭乗橋を提供する。【解決手段】旅客搭乗橋は、入れ子状に嵌合されて、前後方向に相対移動して伸縮可能なトンネル部と、トンネル部の上下動に用いるドライブコラムと、トンネル部の伸縮移動および/または水平動に用いる走行装置13と、を備える。走行装置は、ドライブコラムを支持する支持フレーム17と、支持フレームに搭載されている駆動器16Aと、駆動器により駆動される駆動輪14A、14Bと、駆動輪と障害物との接近検出に用いる検出部と、を備える。検出部39Aは、支持フレームに連結された保持部材33と、保持部材に保持されて、駆動輪の周囲に張られた可とう性部材30と、可とう性部材に張力を付与するテンショナー31と、可とう性部材に作用する張力の変化に基づいて切り替わるスイッチ32と、を備える。【選択図】図2
