Superpac BB     The Superpac BB was probably introduced to replace the Semex in the model lineup, and economy-priced packer offered in smaller body configurations. The BB was not just a "baby Superpac"; although the revolving rake method was the same as the BR series, the crankshaft was carried on much larger bearing wheels, which also served as the cam wheel for the hydraulic rams. The rams were located above the centerline of the crank, pushing downward and pulling upward. The BB may have been a "test bed" to eventually upgrade the BR to the new design, but this never did occur.     The BB was probably first built in the late 1970s, and discontinued circa 1990. All models had ejection blades similar to the BR series, but the smallest versions of the BB had a cable-operated tailgate lift, harking back to the days of the Benne OSEM. This was probably done to save weight and cost. Most of the BB series Superpacs appear to have some type of overhead-mounted tailgate cylinders, as can be seen in the images. A variety of binlifts could be added optionally. The large crankshaft bearing also served as the crank arm and cam to trip the reverse valve The BB had a substantially smaller hopper than the BR, and this one has a rubber flap mounted to the rake With optional hood and container lift, a variety of bins could be emptied Superpac BB fleet showing doors in closed and open positions This Saviem with a Superpac BB is retired, and resides in a peaceful pasture now Small model with cable-operated tailgate lift and lightweight ejector panel 5/16/20 © 2020 All Rights Reserved Photos from factory brochures/advertisements except as noted Logos shown are the trademarks of respective manufacturers
