도면에는 미 도시되었으나, 상기 수납공간(11)에 상기 스탭(10)이 구비되지않은 경우, 닫힌상태를 유지하는 상기 프론트커버(9) 위에 올라서서 상기 연료탱크(4)에 연료를 주유할 수 있다.Although not shown in the drawing, when the staff 10 is not provided in the accommodation space 11, the fuel tank 4 may be refueled by climbing on the front cover 9 that maintains the closed state. have.
한편, 타이어의 펑크 발생시 또는 작업장치에 쌓인 먼지 등을 상기 에어콤프레서(8)를 이용하여 제거할 경우, 상기 에어콤프레서(8)의 콤프레서를 작동시켜 에어탱크에 저장된 압축공기를 배출시키고, 상기 에어탱크에 에어호스를 통해 연결되는 에어건을 이용하여 압축공기 량을 조절하는 작동 원리는, 공지된 기술내용이므로 이들 구성에 대한 상세한 설명은 생략한다.On the other hand, when the puncture of the tire occurs or when the dust accumulated in the work device is removed using the air compressor (8), by operating the compressor of the air compressor (8) to discharge the compressed air stored in the air tank, the air The operating principle of adjusting the amount of compressed air using an air gun connected to the tank through an air hose is a known technology, and thus detailed descriptions of these configurations will be omitted.
여기에서, 상술한 본 발명에서는 바람직한 실시예를 참조하여 설명하였지만, 해당 기술분야에서 숙련된 당업자는 하기의 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경할 수 있음을 이해할 수 있을 것이다.Herein, while the present invention has been described with reference to the preferred embodiments, those skilled in the art will variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below. And can be changed.
전술한 구성을 갖는 본 발명에 따르면, 에어콤프레서를 빗물 등의 외부환경으로부터 보호하여 파손 및 부식에 의한 내구성 저하되는 것을 방지할 수 있는 효과가 있다. 또한 에어콤프레서를 프론트커버 내의 잉여공간에 배치하여 공간활용도를 높이고, 에어콤프레서가 운전실과 인접하여 사용자의 접근이 용이하므로 에어콤프레서를 쉽게 사용할 수 있는 효과가 있다.According to the present invention having the above-described configuration, it is possible to protect the air compressor from the external environment, such as rain water, to prevent degradation of durability due to breakage and corrosion. In addition, the air compressor is disposed in the surplus space in the front cover to increase the space utilization, and the air compressor is close to the cab, so that the user can easily access, there is an effect that can be easily used.
