A working vehicle with a traversing system wherein a front wheel is installed on a swing member rotatable about a vertical axis relative to a body and including a rotating cylinder for rotating the swing member. The entire part of the front wheel is formed compact in connection with a drivingly running device stored in the swing range of the front wheel. A battery mountable on the body comprises a wide front part movable in the vehicle longitudinal direction between rear wheels in the straight forward running attitude. A narrow rear part is positioned between the rear wheels in the transverse running attitude, whereby the attachment and detachment of the wheel can be preformed easily and can be mounted stably.

Working vehicle with traversing system

A vehicle body () is provided with a pair of right and left front wheels () and a pair of right and left rear wheels (), these wheels being adapted to be turned through 90 degrees. The front wheels () are attached to turning members () installed on the vehicle body () for turning around vertical axes (), and turning means () are installed for turning the turning members (). The front wheels () are operatively connected to travel drive means () respectively attached to the turning members (). The travel drive means () extend rearward from the inner sides of the front wheels (). Masts () are installed on the front end of the vehicle body (), and forks () are installed on the masts (). The front wheels are of the type in which they can be steered to turn sideways. And the travel drive means do not require the masts to be positioned more forwardly of the front wheels than necessary and the longitudinal balance can be satisfactorily maintained without increasing the self-weight.

Forklift with transverse travel system

Front wheels and rear wheels are mounted to a vehicle body to be steerable by 90 degrees. Right and left front wheels are connected to the turning members which are capable of rotating around vertical axes in relation to the vehicle body though individual electric drive motors. Each electric motor has an external casing integrally formed with each turning member, and allows a drive shaft and a rotor to be accommodated and rotatable therein. Each drive shaft is connected to the front wheel, and an apparatus for rotating the turning member is provided. This allows the driving front wheels to be steered straight sideways and the electric motor to be readily assembled and arranged compact.
