Safety headset automates noise attenuation

The 3M Pelot series includes the ProTac III Headset, geared for environments where workers are exposed to loud or sharp noises, but need to hear warning signals, alarms, or other sounds in machines and processes. It monitors the surrounding environment and automatically adjusts the amount of attenuation when hazardous noises are present.

Silo fluidizers

The 2-in. (50mm) diameter Mini Fluidizer disk fits in pipes, chambers, chutes and small hoppers to enhance powder and dry bulk material flow in pneumatic conveying systems. Compact size equips the Mini disk to fit curvatures as small as 4 in. In most all applications, the company’s Fluidizers prevent bridging, rat holing and material hang-ups.

Material handling devices

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.
