To provide a track road operation vehicle that expands a movement allowance range of a boom device without impairing safety.SOLUTION: A controller 60 determines performance that determines a movement allowance range of a boom device to first performance when a car body is supported by an iron wheel, determines it to second performance when the car body is supported by a front iron wheel and a rear jack 37, determines it to third performance when the car body is supported by a front jack 31 and the rear jack 37 in a storage state, and determines it to fourth performance when the car body is supported by the front jack 31 and the rear jack 37 in an overhang state. The fourth performance is higher than the third performance, the third performance is higher than the second performance, and the second performance is higher than the first performance. The controller 60 drives the boom device on the basis of the movement allowance range indicated by the determined performance.SELECTED DRAWING: Figure 5

    【課題】安全性を損なうことなくブーム装置の移動許容範囲を広げた軌陸作業車を提供する。【解決手段】コントローラ60は、ブーム装置の移動許容範囲を決める性能を、車体が鉄輪で支持されている場合に、第1性能に決定し、車体が前鉄輪と後ジャッキ37とで支持されている場合に、第2性能に決定し、車体が格納状態の前ジャッキ31及び後ジャッキ37で支持されている場合に、第3性能に決定し、車体が張出状態の前ジャッキ31及び後ジャッキ37で支持されている場合に、第4性能に決定する。第4性能は第3性能よりも高く、第3性能は第2性能よりも高く、第2性能は第1性能よりも高い。コントローラ60は、決定した性能が示す移動許容範囲に基づいて、ブーム装置の駆動を行う。【選択図】図5
