Disclosed is an extensible boom system for a special motor vehicle. The disclosed extensible boom system for the special motor vehicle, which is a boom device mounted on the special motor vehicle, comprises: a first stage boom mounted on a turntable rotatably coupled to a vehicle of the special motor vehicle, fixated to the turntable having an adjustable inclination, and formed in a predetermined length to be long; a second stage boom inserted into the first stage boom, and protruding by a predetermined length toward a rear side of the first stage boom to be withdrawn; a multistage boom coupled to a side end of the first stage boom protruding toward a lower side of the first stage boom from the second stage boom having five connected booms capable of being withdrawn; a second stage withdrawing member disposed on an upper end of the first stage boom, and applying oil pressure such that the second stage boom is pushed toward a front surface of the first stage boom to be withdrawn; and a multistage withdrawing member disposed in the second stage boom, and applying oil pressure such that the multistage boom is withdrawn. According to the extensible boom system for the special motor vehicle which has an extensible boom corresponding to a working height for a high place task; is capable of extending a withdrawn length of the boom by having the second stage boom protruding toward the lower side of the first stage boom; is capable of finely controlling a working height by allowing each boom to be withdrawn in a single or interworking manner; and is able to increase stability of a high place task.

    특장차용 신축붐 시스템이 개시된다. 개시되는 특장차용 신축붐 시스템은 특장차에 장착된 붐 장치에 있어서, 상기 특장차의 차체에서 회전 가능하게 결합된 턴테이블에 탑재되고, 상기 턴테이블에서 고정되어 기울기의 조정이 가능한 일정 길이로 길게 형성된 1단붐; 상기 1단붐의 내부에 삽입되고, 상기 1단붐의 후방으로 일정 길이가 돌출 형성되어 인출 가능한 2단붐; 상기 2단붐에서 상기 1단붐의 하방으로 돌출된 측단의 타 측단과 결합되고, 5개의 붐이 서로 연결되어 인출 가능한 다단 붐; 상기 1단붐의 상단에 배치되고, 상기 2단붐을 상기 1단붐의 전면으로 밀어내어 상기 2단붐의 인출이 가능하도록 유압을 가하는 2단 인출 부재; 및 상기 2단붐의 내부에 배치되고, 상기 다단 붐의 인출이 가능하도록 유압을 가하는 다단 인출 부재;를 포함한다. 개시되는 특장차용 신축붐 시스템에 의하면, 고소작업의 작업높이에 대응되는 신축붐이 형성된 시스템으로, 2단붐이 1단붐의 하방으로 돌출 형성되어 붐의 인출 길이를 늘일 수 있고, 각각의 붐을 단독 또는 연동으로 인출할 수 있어 미세한 작업 높이의 조절이 가능하여 고소작업의 안전성을 높일 수 있는 장점이 있다.
