An automatic and high precision method for getting parameters of four-component system in minitype hydraulic crane was studied. For solving the problem of getting parameters of four-component system in minitype hydraulic crane inefficient and low precision, the mathematic expression of the parameters was found using trigonometric function and kinematics theory, so the computing precision of parameters was increased. Through process analyzing and algorithm design for the movement of four-component system using method of differential coefficient, the problem that it is hard to find the maximum force position of the piston-staff in hydraulic cylinder with traditional method was solved. All parameters were computed by program rapidly and accurately.
