The present invention relates to a forklift preheating apparatus with which a forklift can be preheated within a shorter period of time in a low-temperature region or season. The present invention includes a hydraulic tank (10) storing working oil; a hydraulic pump (20) transporting the working oil from the hydraulic tank (10); and a pressurizing means (100) pressurizing the working oil transported by operation of the hydraulic pump (20). The pressurizing means (100) includes a variable relief valve (110) for passage of the working oil transported by the hydraulic pump (20); a solenoid valve (120) connected to the variable relief valve (110) by a bypass line (122) and operated such that the preheating can be promoted by the working oil being pressurized at a super-cool temperature of each system; and a controller (130) performing pressurization by operating and blocking the solenoid valve (120) upon super-cool temperature detection.

    본 발명은 기온이 낮은 지역 또는 계절에 지게차의 예열시간을 단축할 수 있도록 지게차의 예열장치에 관한 것이다. 본 발명은 작동유가 저장되는 유압탱크(10)와; 상기 유압탱크(10)로부터 작동유를 이송시키도록 하는 유압펌프(20)와; 상기 유압펌프(20)의 가동으로 이송되는 작동유가 승압되도록 하는 승압수단(100)을 포함하고, 상기 승압수단(100)은, 상기 유압펌프(20)에 의해 이송되는 작동유가 통과되도록 하는 가변 릴리프 밸브(110)와; 상기 가변 릴리프 밸브(110)와 바이패스 라인(122)으로 연결되면서 각 계통의 과냉온도시 작동유가 승압되도록 하여 예열이 촉진되도록 작동되는 솔레노이드 밸브(120)와; 과냉온도 감지시, 상기 솔레노이드 밸브(120)를 작동시켜서 폐쇄되도록 하여 승압이 이루어지도록 하는 콘트롤러(130)을 포함하는 것이다.
