Zusammenfassung:	The utility model provides a hydraulic oil heating system. The hydraulic oil heating system comprises a hydraulic oil tank, an engine, a controller, a hydraulic oil heating switch, a cold start heating switch, a hydraulic oil heater, a liquid fuel oil heater and a temperature sensor. The engine is communicated with the liquid fuel oil heater through the first ball valve, the engine is further communicated with the liquid fuel oil heater, the third ball valve, the hydraulic oil heater and the engine through the second ball valve, and the liquid fuel oil heater is communicated with the third ball valve; the hydraulic oil heating switch, the engine, the cold start heating switch, the first ball valve, the second ball valve, the third ball valve and the liquid fuel heater are electrically connected with the controller. According to the utility model, hydraulic oil is rapidly heated in extremely cold weather to meet the viscosity requirement of normal work, the operation preparation efficiency is improved, and the
