The new C-30 C-clamp (photo) permanently mounts on machinery while retracting easily without tools for quick access to the interior of a variety of machinery, such as dryers, mixers, conveyors, tanks and reactors. The new clamp delivers up to 1,700 lb of clamping force to establish a tight seal on machine panels, doors, housings, screen decks and other equipment, even when joining different materials and multiple thicknesses. For quick release and machine access, the C-30 clamp features a proprietary, stainless-steel yoke and roll-pin assembly that allows opening with one hand and no tools without detaching the clamp from the machinery. When cleaning, inspection or maintenance is complete, the clamp may be returned to the closed position at the desired tension in seconds to resume safe machine operation. The C-30 clamp eliminates the need for steel bolts, rivets, welds and other fastening methods that inhibit access. Complete cleaning and product changeovers move smoothly, without concern for confined space entry. The clamp comes in cast aluminum and stainless-steel construction, or in FDA-approved 303 stainless steel to meet USDA regulations and 3-A standards for the food and dairy industries. — The Witte Co., Washington, N.J.
