Horizontal Handle Hold-Down Action Clamp Features Horizontal Hold-Down Action Clamps - The outstanding characteristic is the low height design. Unlike the handle and the hold-down bar of the vertical clamps, those of the horizontal clamps move in opposite directions. These clamps are manufactured with solid or "U" shaped hold-down bars and with various mounting options. The holding capacities range up to 2,400 pounds.   Straight-Line Action Clamps  Features These are manufactured in a variety of models to accommodate a wide range of load ratings (100 pounds - 16,000 pounds). The push/pull handle is easy to operate and moves the plunger of the clamp in and out along its axis. Almost all of these clamps can be locked in two positions, allowing you to use them as either push or pull clamps. Several base mounting options are available. Some models have threaded bodies for thru-hole mounting.   Pull Action Clamps Features The handle can be moved to place the clamping pull bar (hook) around the opposing latch and pressed down to reach the locked position. Ideal for sealing chamber doors or mold closures, the latch clamps provide a powerful closing force, positive holding and convenient operation. Holding capacities range up to 7,500 pounds, and threaded "hook" or "U-bolt" type bars offer an adjustment feature.   Squeeze Action Clamps Features The jaws are locked automatically when closing, as one or both handles are squeezed against the central position. The jaws are drop-forged in steel and most are supplied with 1 or 2 adjustable spindles. Most medium and heavy-duty squeeze action plier clamps feature the DE-STA-CO trigger release for easy one-hand opening. All forged models are heat-treated alloy steel, machined to close tolerances.   Pneumatic Swing Cylinders Features Quick, Clean & Economical DE-STA-CO's new 8400 Series joins the 8000/8100 and 8200/8300 Series, rounding out a versatile, time-saving line of swing cylinders. Ideal for installations where hydraulic power is not suitable, these pneumatic power clamps from DE-STA-CO have all the same quick-acting advantages and can produce up to 160 lbs. clamping force from shop line air pressure (see chart). These double-acting clamps are red anodized aluminum with either a threaded body that permits three mounting options, or a block-style mounting body. Intended for quick clamping in secondary manufacturing operations on metallic or non-metallic products. These clamps offer a combination of features that makes them uniquely adaptable to such applications, as welding and assembly operations. Spindles included.   Pneumatic Heavy Duty Toggle-Lock Features Pneumatic Clamps - DE-STA-CO Pneumatic Clamps use air-actuated cylinders to operate the clamping action. They are ideal for quick clamping in repetitive production operations, and yet are portable and economical to use on short run jobs with temporary fixturing. Pneumatic Clamps are available in many different styles - Swing Cylinders, Hold-Down and Straight-Line Action, Heavy-Duty Toggle-Lock, Heavy-Duty Power Rollers and Low Profile Retractor Clamps - for a wide range of applications. Formula For Calculating Maximum Allowable Inlet Pressure Maximum Line Pressure = Holding Capacity Cylinder Area x Mechanical Advantage Formula For Calculating Exerting Force Exerting Force = Inlet Pressure x MA x Cylinder Area Example For Model 830: Holding Capacity = 2,500 lbs. Inlet Pressure = 80 psig Cylinder Area = 1.767 in.2 MA = 9.8:1 Maximum Line Pressure = 2,500 lbs. 1.767 in.2 x 9.8= 145 psig Exerting Force = 80 psig x 1.767 in.2 x 9.8 = 1,385 lbs. Typical Circuitry It is relatively simple to plumb a pneumatic circuit. There are only five basic components in every fluid power system: Power Source (Air Compressor) Control Valve Actuators (Cylinders, Clamps) Fluid Conditioners (Filters, Regulators) Piping and Fittings
