Types of clamps their applications and industries – a thomasnet buying guide la gastronomie


Cable clamps hold cables or cords together and secure them. Hose clamps hold hoses on the ends of pipe spuds. Hand clamps hold workpieces secure for various work operations. Material handling clamps are used for heavy load lifting or moving and are usually found in use on heavy equipment, but there are versions for lighter loads as well. Pipe clamps are for hanging pipes and conduits.

Types of Clamps Hand (Tool) Hand (Tool) Clamps are hand operated tools used to position and hold workpieces during assembly or while undergoing manufacturing. Key specifications include intended application, clamp type, and grip range, along with the clamp features. Hand (tool) clamps are available in a variety of styles including bar, draw, parallel, and toggle, and are used for various applications such as bookbinding, picture framing, or door making, and as jigs for a number of manufacturing operations. Clamps used with laboratory glassware are included here as well.

Material Handling Material handling clamps are clamping mechanisms used to hold heavy material as it is being lifted or manipulated. Key specifications include the intended application, load capacity, and the orientation of the clamping action. Material handling clamps are used primarily in construction applications for lifting or manipulating large loads. They are commonly found in use on cranes for lifting loads such as rails, girders, pipes, etc. They are used in factories and foundries as well.

Hose Hose Clamps are mechanical devices used to hold hoses or tubes in place on the ends of pipe spuds. Key specifications include the clamp type, diameter, and material. Hose clamps are used wherever a flexible fluid connection must be made, for example, between the water pump of an auto engine and the inlet spud of the radiator. They are made in many sizes and materials, including metal or plastic, depending on the application, and can be designed as single-use or as reusable devices.

Pipe Pipe Clamps are devices used for hanging or securing pipes. Key specifications include the intended application, clamp type, and pipe diameter. Pipe Clamps are used primarily in piping and plumbing applications for the hanging of various types of pipes. Applications include exhaust pipes, guard rails and conduits, among others. There are many styles and sizes available as well as a variety of materials depending on the type of pipe being hung and the environment.

Cable Cable Clamps are mechanical devices used to tie down and hold bundles of cables or cords together. Key specifications include the cable diameter, mounting hole diameter, and the material. Cable clamps are used primarily in manufacturing to assist with routing cables or cords and securing them. They help to relieve stresses in the cables and give them a clean routing. Many materials and sizes are available with various mountings for ensuring a proper and secure fit of cable bundles.

Ground Ground Clamps are devices used for securing grounding wires to grounding rods and pipes. They are used for general grounding of antennas, etc. and for specific tasks such as welding and aircraft refueling. Key specifications include the intended application and material. Several types are available depending on the construction of the ground wire, i.e., bare conductor or shielded.

Applications and Industries Hand clamps for general workholding are available in a variety of styles. Some of the more common varieties include C clamps, bar clamps, toggle clamps, etc. Clamps with soft faces are made especially for woodworking and cabinetmaking. Woodworking clamps typically have speed features to allow them to be brought up to the work quickly prior to applying clamping pressure. A host of hand clamp styles are used in general fixturing applications, for metalworking, etc., and they are typically adjustable with quick release features to permit work to be locked into fixtures and removed rapidly after any machining, etc. is completed. Clamp styles here include hold down, toggle, push-pull, Carver, etc.

A step up from hand clamps are the power workholding varieties that are pneumatically or hydraulically actuated and sometimes made to swing toward and away from the workpieces when they are clamped and unclamped. These are located by searching under Type: Swing. Material handling clamps are often used in so-called below the hook applications, where they are suspended from crane-, forklift-, etc. mounted hooks and used to pick up steel plate and the like. Often they incorporate a gripping or latching mechanism that uses the suspended weight of the plate, beam, etc. to provide the necessary holding force.

Hose clamps come in a variety of styles, from the reusable worm gear style to the economical ear clamps that are crimped in place for one-time use. Ear clamps, wire clamps, etc. are particularly prevalent in the auto industry. Constant torque clamps are available for expanding/contracting hose assemblies. Pipe clamps are used as elements in pipe hangers, as assembly devices for exhaust systems (muffler clamps), and as connectors for sanitary (quick connect) piping systems.

Pipe clamps often incorporate a U-bolt and a saddle which is tightened down with nuts to squeeze the mating pipes together. Clamps for repairing pipe can be found under Couplings (Fittings). Ground clamps are often made of conductive material such as brass to insure the transmission of electricity through them. Cable clamps are used for affixing cables to walls, etc. and rely on friction and pinch to secure the cable jacket or sheath. Some cable clamps are lined with cushioning to further their grip and protect the cable sheath from abrasion.

Considerations Selecting hand clamps is mostly a matter of identifying the clamp type or application. Hold down clamps, for example, are popular for securing work on tables or benches, as are push-pull clamps. Other clamps, such as bar or squeeze clamps, are useful for gluing up laminated assemblies and the like. Clamps for laboratory glassware can be found by searching under intended application the glassware type, be it flask, beaker, etc.

Hose and pipe clamps are generally specified by diameter, with many hose clamps operable over a range of diameters. Some hose clamps require special tools for crimping them, such as ear clamps, while others, such as worm gear style (or screw) clamps, can be opened and closed with screwdrivers, wrenches, etc. Manufacturers usually opt for economy and installation ease when selecting clamps, whereas do-it-yourselfers might spring for costlier clamps that don’t require special tools for installing.

Material handling clamps are selected for the material or shape being hoisted and usually by capacity. They normally rely on a squeeze or camming mechanisms to grip plates, sheets, etc. Ground clamps are usually selected by cable type—bare or sheathed—and by the grounding rod type. Cable clamps are selected mainly based on cable size.

Load Capacity Similar to maximum clamping force, this attribute applies to material handling clamps and pipe clamps where loads are suspended. For pipe clamps it is usually expressed in lbs., and for material handling clamps, in tons or lbs. Maximum Torque This attribute applies to hose clamps and is usually expressed in in.-lbs. or ft.-lbs. It pertains to the torque requirements of the screw, bolts, etc. that tighten the clamp.
