These Destaco 81L Series pneumatic power clamps are designed for gripping, clamping, system checking, fixturing and testing, welding, CNC machining and locating applications in the aerospace, automotive and food & packaging industries. They have an aluminium body and a horizontal clamping steel arm for increased strength and durability. These pneumatic clamping devices are used to hold products securely in place to ensure error free operations and are intended for harsh welding environments that demand superior clamping power for improved durability, reliability & precision. Destaco pneumatic clamps are integrated with hardened rivets & bushings at pivot points to fix, rotate & move the handle bar for the required work position. They contain a pneumatic cylinder with an input port for connecting to a source of compressed air. These units are equipped with a patented Toggle Lock mechanism for locking the clamp in fixed position if sudden pressure drop or hose disconnection is detected. Destaco 81L Series clamps can handle a maximum load of 73.8 lb at pressures up to 72 psi, within temperatures ranging from -14 to 145 degrees Fahrenheit. These pneumatic power clamps are compatible with Destaco seal kits (81L16-1-00) for unobstructed functioning of the clamps as well as accommodate sensors (8EA-109-1) that are mounted to the cylinders having T-slot grooves. These sensors are activated with a magnetic ring which is installed on the cylinder of the clamps.
