ABSTRACT:
A conveying carrier is arranged to be self-propelled and move along a conveying passage having a pit formed therebelow. A track covers the top side of the pit flush with the road surface of the conveying passage. A plurality of wheels are attached to the conveying carrier with at least the front wheels being casters. A steering frame is pivotally supported on the conveying carrier and is turnable about a vertical steering axis line. A driving wheel and motor are attached to the steering frame, with the driving wheel being positioned to contact the track at a location substantially directly below the vertical steering axis line. A guide member is guided by a guide rail laid in the pit and connected to the steering frame through a slit in the widthwise center of the track. The pit is a substantially U-shaped track frame buried in the widthwise central portion. The track is formed of a pair of cover plates which are detachably mounted on the upper ends of side plates on both sides of the track frame as to leave the slit therebetween.
