Crane Q gives the low-down The latest and most advanced version of Konecranes’ Crane Q geometric survey is being introduced to Australasia to provide crane users with the most accurate data on the geometry of their crane, which is essential to safety and optimising service life. The CraneQ survey is applicable to all kinds of overhead cranes and particularly relevant to those in heavy duty industries such as steel, paper, manufacturing and mining, where cranes are subjected to harsher operating conditions and more demanding uses. “CraneQ is based on advanced and traditional measurement methods. Proprietary software and skilled survey technicians provide an extremely accurate geometric analysis of your crane. In addition to the survey results, we can share our expertise to help you to plan corrective actions,” says Joseph Cefai, consultation services manager, Konecranes Australia and New Zealand.

He is senior author of a study in the journal Scientific Reports that explored degradation of tungsten under reactor-relevant conditions. Because tungsten has the highest melting point of all metals, it is a candidate for plasma-facing materials. Owing to its brittleness, however, a commercial power plant would more likely be made of a tungsten alloy or composite. Regardless, learning about how energetic atomic bombardment affects tungsten microscopically helps engineers improve nuclear materials. “Inside a fusion power plant is the most brutal environment engineers have ever been asked to design materials for,” Mr Parish says. “It’s worse than the interior of a jet engine.” Researchers are studying the interaction of plasma and machine components to make materials that are more than a match for such harsh operating conditions. Materials reliability is a key issue with current and new nuclear technologies that has a significant impact on construction and operating costs of power plants. So it is critical to engineer materials for hardiness over long lifecycles. For the current study, researchers at the University of California, San Diego, bombarded tungsten with helium plasma at low energy mimicking a fusion reactor under normal conditions. Meanwhile, researchers at ORNL used the Multicharged Ion Research Facility to assault tungsten with high-energy helium ions emulating rare conditions, such as a plasma disruption that might deposit an abnormally large amount of energy. Using transmission electron microscopy, scanning transmission electron microscopy, scanning electron microscopy and electron nanocrystallography, the scientists characterized the evolution of bubbles in the tungsten crystal and the shape and the growth of structures called “tendrils” under low- and highenergy conditions. They sent the samples to a firm called AppFive for precession electron diffraction, an advanced electron crystallography technique, to infer growth mechanisms under different conditions. The first of the new 6mm and 8mm DC servo motors to arrive downunder. Close inspection of the gear motor combination reveals the extent of motor customisations possible, normally for niche hand-built servo motor and gearhead combinations that the Swiss engineers have become famous for. Completely configured by the end user, Maxon motors’ new micro DC motors system of online motor design and fully automated construction is set to change the future of motor manufacturing technology. Without human interference the tiniest of microdrives can be tailored to the application via an online tool. From the shaft length, diameter and flat features to the mounting method, gearhead reduction, winding characteristics, cable length and connector type. All direct from the motor design portal to the automated manufacturing line. Features include laser welded steel construction, dual stainless ball bearings and integral strain relief on a motor with only 6mm outer diameter, over 17,000rpm at much lower noise levels than previously attained and torque levels to 200mNm make the new 6mm and 8mm servo gear motors incredibly power dense. The ultra-small DC servo motors have linear control characteristics, zero magnetic detent (cogging) making them suitable for applications such as micro pumps, medical and laboratory dosing devices and robotics.
