ABSTRACT:
A floor sweeping attachment attachable to the underside of a factory fork lift truck. The device is in the form of a rectangular frame mounted on wheels to which a rotary brush sweeper unit is fastened. The wheel units of the frame are each mounted on a rotatable vertical pin, slidably fitted in a vertical tube of the frame. A pair of tapered wheels are fastened to the upper section of each wheel unit and ride under and lift up the frame when the device is moved sidewise to lift the brush sweeper unit above the floor level so as to avoid wearing of the brush bristles and brush sweeper wheels when the attached lift truck is not moving in a general forward or rearward motion.
