Beschreibung
Zusammenfassung:	The utility model discloses a hydraulic control system of an engine installation vehicle, which comprises a hydraulic oil tank (1), a load-sensitive pump (2), a load-sensitive proportional multi-way valve (10), a lifting oil cylinder (12) and a parking oil cylinder (15), the load-sensitive pump (2) is connected with the hydraulic oil tank (1), the load-sensitive pump (2) is communicated with the load-sensitive proportional multi-way valve (10) through an oil pipe, and the lifting oil cylinder (12) is connected with the lifting oil cylinder (12). And the load-sensitive proportional multi-way valve (10) is respectively connected with a lifting oil cylinder (12) and a parking oil cylinder (15) through oil pipes. According to the utility model, the load-sensitive proportional multi-way valve and the displacement sensor are adopted to carry out closed-loop precision control on the lifting oil cylinder, the load-sensitive proportional multi-way valve realizes synchronous control and independent control on the parki
