The utility model discloses an engine rear power take-off simulation load device for engineering machinery, which comprises an engine arranged on a test bed, and a gear shifting pump, a steering pump and a vibration pump which are driven by an engine crankshaft driving gear train, and a first hydraulic oil tank and a second hydraulic oil tank are arranged on the test bed. The vibration pump and the gear shifting pump are communicated with the first hydraulic oil tank through an oil inlet and outlet pipeline, the steering pump is communicated with the second hydraulic oil tank through an oil inlet and outlet pipeline, and electric control proportional valves are arranged on oil outlet pipelines of the steering pump, the vibration pump and the gear shifting pump and are in signal connection with the measurement and control system. And the measurement and control system controls each electric control proportional valve to be opened according to a set program. According to the utility model, in an engine developm
