Till: EXPERTS Email your questions about bolt securing to [email protected] FRIDA CULLIN STEVE BUSALACCHI Do you have a question about bolt securing? Put the Nord-Lock Material fatigue Q: What is the fatigue phenom- A: Material fatigue occurs when a component is subjected to cyclic loading. If the cyclic loads applied are too high, microscopic cracks will form, and when they reach a critical size the part will fracture. Material fatigue occurs at a stress level below the yield strength of a When designing a bolted joint it is crucial to minimise the cyclic loads applied to the bolt to avoid...

With Superbolt® you can tighten even the largest bolts with hand tools. Like the Nord-Lock product range, the result is safer, faster and more accurate bolting, making them a perfect match. Bolted takes a closer look at Nord-Lock's latest DAVID WILES CHRISTER EHRLING, SUPERBOLT & CERN ^ ment, which came in 1974 while scrap choppers in a US steel mill, solved at a stroke two basic problems with big bolts. One is that they take a massive amount of torque to tighten. The second is that they have a nasty habit of working loose. When told that otherwise perfectly-functioning scrap chopper required...

As a bolt’s diameter increases, the torque required for tightening soars, but Superbolt tensioners reduce the torque required by splitting one big torque into a number of smaller torques. of applications, from satellites to submarines to the Large Hadron Collider at CERN. The problem Steinbock tackled is the fact that for bolt diameters bigger than about M24, it is very difficult to create enough torque to tighten or loosen a bolt. Simple physics shows that the torque needed to properly pre-stress a bolt increases by the third power of the bolt diameter. Therefore as the bolt diameter increases,...

Gold award from CERN SUPERBOLT SUPPLIED MORE than 1,500 high-strength mechanical tensioners, expan- sion bolts and multi-jackbolt tensioners to the CERN Large Hadron Collider in Switzerland. Multi-jackbolt tensioners were used for an ap- plication requiring a very high clamping force, but with limited space for tightening the bolts. Since only hand tools were required, the need to create anchor points for heavier tightening equipment was eliminated. Superbolt won the CMS gold award for its contribution to the Ideal mine solution THE SEVERE ENVIRONMENT of an under- ground coal mine takes a brutal...

The ABB DC drives are designed for most industries, including metals, mining, wire manufacturing, oil rigs and cranes. 12 bolted # 1 2012

i'i-w-i.H Electric motors are often called the "workhorses of the industry", running all kinds of machinery ranging from escalators and ski lifts to huge port cranes. Heavy mechanical movements require a reliable drive that ensures the best torque, speed, and motor efficiency. This reliability often starts with the right bolt securing system.
