Equipped with the Sidewinder lever handle, the new CM Tornado 360° enables operators to be more productive with significantly less effort compared to conventional ratchet lever tools, product engineers contend. The Sidewinder lever handle features a 360-degree rotating lever and fold-out revolving handle. Working in unison, they allow the operator to realize the full potential of 360-degree rotation from a safe, ergonomic position. The design reduces repetitive wrist action experienced with traditional lever hoists, letting the operator utilize a full range of motion to work up to 12 times faster. The Tornado’s double-reduction gearing and high-quality bearings decrease pull force by up to 30 percent, minimizing operator fatigue as compared to using conventional ratchet lever tools. The Tornado is available in ¾- and 1.5-ton capacities with standard lifts up to 20 feet.

From Rice University, Houston … Bringing order to disorder is key to making stronger and greener cement and concrete. In National Science Foundation and U.S. Department of Energy-backed research, Rice University scientists have decoded the kinetic properties of cement and developed a way to “program” the microscopic, semicrystalline particles within. The process turns particles from disordered clumps into regimented cubes, or spheres that combine to make the material less porous and more durable.
