To provide a ladder/boom loading vehicle that shortens a projecting duration of an outrigger and enhances operability and safety during operation of a ladder.SOLUTION: A ladder/boom loading vehicle includes: a plurality of outriggers 8 provided on a vehicle body 2; an outrigger cylinder 12 having an extension-side oil chamber 121 and a contraction-side oil chamber 122; an oil tank 13; a hydraulic pump 14; and an outrigger speed increase switching valve 23. When an operation for moving one of outriggers 8 provided on the left side or one of outriggers 8 provided on the right side to a projecting side is selected, a controller selects an oil tank 13 as a destination of oil discharged from the contraction-side oil chamber 122 by turning off the outrigger speed increase switching valve 23, and when an operation for simultaneously moving two or more of the outriggers 8 provided on the left side or two or more of the outriggers 8 provided on the right side to the projecting side is selected, the controller selects the extension-side oil chamber 121 as the destination of oil discharged from the contraction-side oil chamber 122 by turning on the outrigger speed increase switching valve 23.SELECTED DRAWING: Figure 3
【課題】梯子/ブーム搭載車において、アウトリガの張り出し時間を短縮し、また梯子操作時の操作性や安全性を高めること。【解決手段】車体2に複数設けられたアウトリガ8と、伸側油室121及び縮側油室122を有するアウトリガ用シリンダ12と、オイルタンク13と、油圧ポンプ14と、アウトリガ増速切換弁23とを備え、制御器は、左側に設けられたアウトリガ8のうちの一本、又は右側に設けられたアウトリガ8のうちの一本を張り出し側へ動かす操作が選択された場合、アウトリガ増速切換弁23をオフとすることで縮側油室122から吐出された油の行先をオイルタンク13とし、左側に設けられたアウトリガ8のうちの二本以上、又は右側に設けられたアウトリガ8のうちの二本以上を同時に張り出し側へ動かす操作が選択された場合、アウトリガ増速切換弁23をオンとすることで縮側油室122から吐出された油の行先を伸側油室121とする。【選択図】図3
