The hydraulic system comprises an action assembly, a flow dividing assembly, an oil tank assembly and a control valve, the action assembly comprises at least two hydraulic cylinders, the flow dividing assembly comprises at least two flow dividing motors, and the oil tank assembly comprises an oil tank, an oil inlet path, a first oil return path and a second oil return path. When the control valve controls the second oil inlet to be communicated with the oil inlet path, hydraulic oil in the oil tank passes through the oil inlet path and the second oil inlet, passes through the flow dividing motor of the flow dividing assembly and enters the piston cavities of the hydraulic cylinders, and due to the flow dividing effect of the flow dividing assembly, the flow of the hydraulic oil entering the piston cavities of the hydraulic cylinders is equal. Therefore, the hydraulic cylinders can synchronously and stably extend out; when the control valve controls the first oil inlet to be communicated with the oil inlet path, hydraulic oil in the oil tank enters the rod cavity of the hydraulic cylinder through the first oil inlet, and the piston rod of the hydraulic cylinder is pushed to retract stably. The invention further provides lifting equipment which comprises the hydraulic system.

    本发明公开一种液压系统,包括动作组件、分流组件、油箱组件和控制阀,其中,动作组件包括至少两个液压缸,分流组件包括至少两个分流马达,油箱组件包括油箱、进油油路、第一回油油路和第二回油油路。当控制阀控制第二进油口与进油油路相连通时,油箱内的液压油经由进油油路和第二进油口,经过分流组件的分流马达,进入液压缸的塞腔内,由于分流组件的分流作用,使得进入各液压缸塞腔内的液压油的流量相等,从而能够使各液压缸同步、平稳伸出;当控制阀控制第一进油口与进油油路相连通时,油箱内的液压油经过第一进油口进入液压缸的杆腔,推动液压缸的活塞杆平稳收回。本发明还提供一种举升设备,包括上述的液压系统。
