The Uhing-Easylock®, available from Techna International, provides a tried and tested system for the secure clamping of items (spools, reels, etc) onto rotating shafts, in a range of sizes for shaft diameters of 10, 15, 20, 22, 25, 30, 35 and 40mm, with tension from 400N on the smallest unit up to 5,000N on the largest unit. The units comprise a fixed cone, an interchangeable cone point and a tensioning clamping ring, which is increasingly offset to the shaft with which it engages, in response to axial or tensioning forces, so creating an increasing friction contact. The greater the tensioning force, the greater the clamping effect of the ring. As the item is held firmly between the fixed cone and the clamping cone, braking moments are able to be transmitted from the shaft to the item being clamped, allowing fast stopping of the machine if a fault occurs. These units provide several advantages including: • Single-handed operation for assembly and disassembly • Shortest possible changeover times • No tools required Tried and tested system

shaft diameter sizes of 8, 10, 12, 15, 16, 20 and 22mm, utilises a clamping ring which is offset to the shaft to provide clamping forces from 200N to 320N depending on size. The Fastlock range is available in 15 metric shaft diameter sizes from 10mm to 56mm and in 14 imperial sizes from 0.375 (3/8") to 2". Techna International Ltd – UK Website : www.techna.eu

• High tensioning forces on a plain, round, greaseless shaft • Suitable for use with driven shafts • Emergency stop secure • Maintenance-free • Suitable for static applications • Resistant to vibration

For less arduous clamping operations, Techna provides two ranges of spool clamping collars both with single-handed, quick release operation, without the need for tooling. The Uhing “U-Clip”, in a range of
