The invention relates to hydraulic self-locking type cross-shaped sliding rail rescuing equipment, in particular to emergency rescuing equipment which is provided with a telescopic rod, provided witha cross-shaped sliding rail at the top end of a hydraulic jack and used for automobile rescue, and is capable of achieving load bearing and rapid supporting. The telescopic rod is arranged between thecross-shaped sliding rail and the hydraulic jack, and four sets of tooth-shaped protrusions are arranged in an outer casing pipe body of the telescopic rod. An inner casing pipe body is provided withfour sets of tooth-shaped protrusions. The equipment can achieve self rescue through independent operation, and manpower, material resources and time are greatly saved. The cross-shaped sliding railon the jack of the equipment is used for supporting a wheel of an automobile, self rescue is finished by adjusting the longitudinal direction and the transverse direction of the cross-shaped sliding rail, the automobile can horizontally move in the longitudinal direction and the transverse direction through the cross-shaped sliding rail, operation is safe in a labor-saving manner, the purpose of convenient operation is achieved, and practicability is high.
