PROBLEM TO BE SOLVED: To timely check an image of a rear view of a machine body on a monitor in an irregular ground transport vehicle in which a vessel is arranged behind an operator cab on a turning body.SOLUTION: An irregular ground transport vehicle equipped with a rear view monitoring camera, in which a turning body is rotatably provided on a travelling body includes pressure detectors for detecting pressures A1 and A2 of ports on one side and on the other side of a left travelling hydraulic motor respectively, pressure detectors for detecting pressures B1 and B2 of ports on one side and on the other side of a right travelling hydraulic motor, a direction detector for detecting the direction of the turning body with respect to the travelling body, a direction determination device for determining the direction of the turning body with respect to the travelling body based on a signal of the direction detector, a backward travelling detection device for detecting backward travelling which is a travelling operation of the travelling body to the rear side based on the result of the determination by the direction determination device, a large/small relation between the pressures A1 and A2, and a large/small relation between the pressures B1 and B2, and a display control device for causing an image taken by the rear view monitoring camera to be displayed on a monitor in an operator cab when backward travelling is detected by the backward travelling detection device.SELECTED DRAWING: Figure 10
【課題】旋回体上における運転室の後側にベッセルを配置している不整地運搬車において適時に機体後方の映像をモニタで確認できるようにする。【解決手段】走行体上に旋回体を旋回可能に設け、後方監視カメラを備えた不整地運搬車において、左走行用油圧モータの一方側及び他方側のポートの圧力A1,A2をそれぞれ検出する圧力検出器、右走行用油圧モータの一方側及び他方側のポートの圧力B1,B2をそれぞれ検出する圧力検出器、走行体に対する旋回体の向きを検出する方向検出器、方向検出器の信号を基に走行体に対する前記旋回体の向きを判定する方向判定装置、方向判定装置の判定結果、圧力A1,A2の大小関係、及び圧力B1,B2の大小関係を基に、後方側への走行体の走行動作である後進を検出する後進検出装置、及び後進検出装置で後進が検出されている場合に後方監視カメラで撮影した映像を運転室のモニタに表示させる表示制御装置とを備える。【選択図】 図10
