A hydraulic pilot handle used for a crane and capable of intelligently recognizing and controlling the direction comprises a handle assembly, the handle assembly is connected with a valve body through a universal shaft, the valve body is provided with a plurality of valve rod assemblies, each valve rod assembly corresponds to the movement direction of the handle assembly, a circular cam is arranged above the valve rod assemblies and connected with the handle assembly, and the valve rod assemblies are connected with the circular cam. The valve rod assembly is connected with a pressure sensor, and the pressure sensor is connected with the system controller. According to the hydraulic pilot handle with the intelligent control direction recognition function for the crane, the pressure sensor is arranged at each valve rod assembly, the valve rod assemblies in which direction act are detected through the pressure sensors, and therefore the specific control direction of handle operation is detected; the function of recognizing the specific control direction of handle operation by converting mechanical pressure generated by handle action into corresponding electric output signals is achieved, the structure is compact, cost is low, and reliability is high.
