The invention discloses a fork truck used in a coal mine tunnel and belongs to the technical field of cargo transportation equipment. In order to solve the technical problems, a fork truck device which can be adjusted in multiple directions in a tunnel is provided. The fork truck is convenient to use, can avoid barriers effectively and reduces labor intensity of workers. The adopted technical scheme is that the back end of a fork arm is hinged to a bearing vehicle body, the front end of the fork arm is hinged to the upper end of an outer frame, the lower part of the fork arm is connected with the bottom surface of the fork arm through a rotary cylinder, the inner part of the outer frame is a cavity and is provided with an inner frame through a lifting cylinder, the cylinder body of the lifting cylinder is hinged to the inner wall of the upper part of the outer frame, the end part of the piston rod of the lifting cylinder extends downwards and is fixedly connected with the upper end of the inner frame, one side of the outer frame is provided with a guide groove, the sidewall of the inner frame is fixedly provided with a fork plate, and the vertical running track at the joint of the fork plate and the inner frame corresponds to the guide groove. The fork truck is mainly used for transporting middle-large size material in the coal mine tunnel, and realizes mechanization of the material transportation in the narrow tunnel.
