Beschreibung
Zusammenfassung:	The invention provides a high-altitude parachuting simulation hydraulic lifting system. The high-altitude parachuting simulation hydraulic lifting system comprises an oil supply assembly, a control assembly and a lifting mechanism. The oil supply assembly comprises an oil tank and a motor pump set. The control assembly comprises a proportional reversing valve and an adjustable overflow valve. The proportional reversing valve is provided with a P port, a T port, an A port and a B port. When the left station of the proportional reversing valve works, the port P is communicated with the port A, and the port B is communicated with the port T; when the middle station of the proportional reversing valve works, the oil ports are disconnected from one another; and when the right station of the proportional reversing valve works, the P port is communicated with the B port, and the A port is communicated with the T port. An oil inlet of the lifting mechanism and one end of the adjustable overflow valve are connected to
