The invention discloses a self-traveling equipment train used for a fully mechanized coal mining face. The self-traveling equipment train mainly comprises two flat cars, a transverse shift device, support devices, connecting frames and a hydraulic control system, wherein the flat cars are lapped in series front and back; the transverse shift device is connected between the two flat cars, and is used for driving the two flat cars to move front and back; the support devices are vertically fixed on each flat car by the corresponding connecting frame, and are capable of supporting the flat car to keep fixed on site; the hydraulic control system is used for controlling the sequential action of the transverse shift device and the support devices. The self-traveling equipment train used for the fully mechanized coal mining face is simple in structure and easy to operate and control, the alternate movement and the steady support effect of the two flat cars are realized by the stretch and the shrinkage of the transverse shift hydraulic cylinder and a piston cylinder, the stability of the self-traveling equipment train on the fully mechanized coal mining face with a large dip angle is improved, the occurrence of self-slippage phenomenon is prevented, the mobility of the train is controlled at any time according to needs, and the maneuvering characteristic is improved.
