Title (EN) SAFETY SYSTEM FOR CONSTRUCTION MACHINE
(FR) SYSTÈME DE SÉCURITÉ POUR ENGIN DE CHANTIER
(KO) 건설 기계의 안전 시스템
Abstract: front page image
(EN)The present invention relates to a safety system for a construction machine. A safety system for a construction machine according to an embodiment of the present invention comprises: a pilot pump for supplying a pilot hydraulic oil; a plurality of spools each of which is operated by the pilot hydraulic oil to control the supply of a main hydraulic oil and has a signal portion formed in one area thereof; a signal line that sequentially connects the pilot pump with the signal portion of the plurality of spools and discharges, into a hydraulic tank, the pilot hydraulic oil which the pilot pump has supplied; and a pressure sensor for measuring the pressure of the signal line.
(FR)L'invention concerne un système de sécurité pour engin de chantier qui, selon un mode de réalisation, comprend: une pompe pilote pour fournir une huile hydraulique pilote; une pluralité de bobines dont chacune est actionnée par l'huile hydraulique pilote pour commander l'apport d'une huile hydraulique principale, et présente une zone dans laquelle est formée une partie signal; une ligne de signal qui raccorde séquentiellement la pompe pilote avec la partie signal de la pluralité de bobines et décharge, dans un réservoir hydraulique, l'huile hydraulique pilote fournie par la pompe pilote; et un capteur de pression pour mesurer la pression de la ligne de signal.
(KO)본 발명은 건설 기계의 안전 시스템에 관한 것으로, 본 발명의 실시예에 따른 건설 기계의 안전 시스템은 파일럿 작동유를 공급하는 파일럿 펌프와, 상기 파일럿 작동유로 동작하여 메인 작동유의 공급을 제어하고 일영역에 신호부가 형성된 복수의 스풀과, 상기 파일럿 펌프와 상기 복수의 스풀의 상기 신호부를 차례로 연결하고 상기 파일럿 펌프가 공급한 파일럿 작동유를 유압 탱크로 토출하는 신호 라인, 그리고 상기 신호 라인의 압력을 측정하는 압력 센서를 포함한다.
