The four-way forklift belongs to the technical field of forklifts and comprises a chassis, a portal and a forward moving support, the chassis comprises wheels, a frame, a driving system and a transmission system, the driving system comprises a battery and a hydraulic system, the frame comprises two front wheel carriers and a rear saddle, front wheels are mounted at the ends of the front wheel carriers, and rear wheels are mounted in the middle of the rear saddle. The transmission system comprises a telescopic mechanism, a rear oil cylinder for driving the rear wheels to steer, a left oil cylinder and a right oil cylinder, the left oil cylinder and the right oil cylinder respectively drive the front wheels to steer, the front wheels and the rear wheels are both connected with the transmission system, the portal frame is installed on a forward-moving support, the forward-moving support is connected with the frame, and the forward-moving support is located between the two front wheel frames. The problems that in the prior art, when a forklift forks and carries super-long goods, transverse stability is poor, transverse movement cannot be achieved, the turning radius is large, movement is not flexible enough, the requirement for the movement space is large, autonomous walking work cannot be achieved, the energy density of an electric forklift is insufficient, and a gearbox of an internal combustion engine forklift occupies space or is polluted by noise and tail gas can be solved.
