Abstract
The present disclosure discloses an industrial vehicle driving in four directions and a traveling mechanism for the industrial vehicle. The traveling mechanism for the industrial vehicle driving in four directions comprises four wheel sets at bottom of the vehicle body, the wheel sets are sequentially connected to form a quadrangle; one wheel set is a rotating wheel set, another wheel set is a reversible directional wheel set, and the axis direction of the rotating wheels is switched between two directions through the rotating action of a rotating shaft of the wheel set; the other two wheel sets are variable-state wheel sets, and the rotating wheel state are switched between a directional state and a follow-up universal state. The present disclosure has simple structure, low cost, good supporting stability, and usage range, usage efficiency and maneuvering capability of the industrial vehicle are facilitated.
