PROBLEM TO BE SOLVED: To provide a highly efficient system capable of preventing secondary disaster.SOLUTION: In the special fire-fighting vehicle, water is discharged by using a water discharger 1, and a device driven by hydraulic pressure actuators 3-8 is mounted. The special fire-fighting vehicle comprises a non-positive-displacement pump 21 and a positive-displacement pump 22 driven by a power source (an engine 20) a reservoir tank 30 to store water a fire-fighting water suction path 31 to guide water in the reservoir tank 30 to a suction port of the non-positive-displacement pump 21 a fire-fighting water supply path 41 to feed water discharged from the non-positive-displacement pump 21 to the water discharger 1 an actuation water suction path 32 to guide water in the reservoir tank 30 to a suction port of the positive-displacement pump 22 an actuation water supply path 42 to feed water discharged from the positive-displacement pump 22 to the hydraulic pressure actuators 3-8 and a fire-fighting water pressure introduction path 43 to guide fire-fighting water pressure in the fire-fighting water supply path 41 to the actuation water suction path 32.COPYRIGHT: (C)2009,JPO&INPIT【課題】二次災害を防止し高効率のシステムを提供する。【解決手段】放水具1を用いて放水を行うとともに、液圧アクチュエータ3~8によって駆動される機器を搭載する特殊消防車両であって、動力源(エンジン20)によって駆動される非容積ポンプ21及び容積ポンプ22と、水を貯留するリザーバタンク30と、リザーバタンク30の水を非容積ポンプ21の吸込口に導く消防水吸込通路31と、非容積ポンプ21から吐出される水を放水具1に供給する消防水供給通路41と、リザーバタンク30の水を容積ポンプ22の吸込口に導く作動水吸込通路32と、容積ポンプ22から吐出される水を液圧アクチュエータ3~8に供給する作動水供給通路42と、消防水供給通路41の消防水圧を作動水吸込通路32に導く消防水圧導入通路43とを備える。【選択図】図1
