A full line of heavy-duty rotary-electric vibrators and drives has been designed specifically for screening machines and other vibratory applications. All provide continuous maximum-force operation — from 30 lb to more than 40,000 lb. These dust-tight, splash-proof motors provide excellent field performance in harsh environments. Heavy-duty construction — including ductile-iron castings, steel end covers and high-alloy fasteners — ensures a long life. The motors are available in 3600-, 1800-, 1200- and 900-RPM models, from 1/50th to 17.5 hp. All units can be mounted horizontally or vertically.
