ABSTRACT:
The relative movement between the draft frame and the bowl member of a scraper bowl-lift apparatus is controlled by one or more bowl-lift motors. The longitudinal centerline of the motor passes through a spreader member of the draft frame. One end of the motor is pivotally connected to a shrouded motor support at a location above the spreader member while the other end of the motor is pivotally connected to a preselected portion of the bowl member. By so orienting the bowl-lift motor relative to the spreader, the entire draft frame apparatus is of improved strength and efficiency.
