PROBLEM TO BE SOLVED: To provide an on-rail work vehicle in which both of work efficiency and safety on a track are achieved.SOLUTION: An on-rail work vehicle operates a boom device with first performance (S12) in the case that an outrigger is in a support state (S11: Yes), operates the boom device with second performance lower than first performance (S19) in the case that an iron wheel is in an overhang state (S13: Yes), a turn table is in a storage state (S14: Yes), the outrigger is in a non-support state (S11: No), and a driving force from a driving source is in a non-transmission state in which said force is not transmitted to the iron wheel (S15: Yes), and operates the boom device with third performance lower than second performance (S21) in the case that the iron wheel is in a storage state, and the outrigger is in the non-transmission state (S11: No and S13: No).SELECTED DRAWING: Figure 3
【課題】軌道上での作業効率と安全性とを両立させた軌陸作業車を提供することにある。【解決手段】軌陸作業車は、アウトリガが支持状態である場合に(S11:Yes)、第1性能でブーム装置を動作させ(S12)、鉄輪が張出状態で(S13:Yes)、転車台が格納状態で(S14:Yes)、アウトリガが非支持状態で(S11:No)、且つ駆動源からの駆動力が鉄輪に伝達されない非伝達状態である場合に(S15:Yes)、第1性能より低い第2性能でブーム装置を動作させ(S19)、鉄輪が格納状態で且つアウトリガが非支持状態である場合に(S11:No&S13:No)、第2性能より低い第3性能でブーム装置を動作させる(S21)。【選択図】図3
