AGGREGATES MANAGER / November 2016 9 Peer-to-peer collision avoidance system Proximity Awareness, from Caterpillar, is a new collision avoidance system for surface vehicles. Part of the Cat MineStar Detect capability set, the system uses peer-to-peer communications leveraged by the automotive industry. It is said to deliver fast and reliable communication between vehicles and presents collision avoidance information to operators without the need for a robust radio network covering the site. Onboard hardware can be fitted to light vehicles and to any brand of surface min- ing equipment. Fewer components are required compared to the previous system, which uses a WiFi network. The result is reduced space required onboard vehicles, fast installation, and lower cost. The system provides three onboard alarming levels. Zones, which define alarming, are operator configurable. Alarming priority ranges from low to critical. Caterpillar | www.cat.com Excavator offers high production rates Volvo introduces its largest North American excavator to date, the EC750E. The 75-ton unit was designed to deliver heavy lifting power and high productivity without sacrificing fuel efficiency. The machine is said to deliver up to 15 percent higher productivity with 5 percent more fuel efficiency than its predecessor, the EC700CL. The excavator is powered by a 516-horsepower, Tier 4 Final, Volvo D16J engine. When combined with larger diameter boom cylinders and increased working pressure, the unit delivers a 7-percent in- crease in digging force and a 4-percent boost in hydraulic flow. A new range of buckets — including general purpose heavy-duty, and extreme-duty designs — also contributes to increased productivity by offering up to 10 percent more bucket space. Volvo Construction Equipment America | www.volvo.com Effective sampling system McLanahan combined its experience in sampling systems and wet mineral processing to develop the Vezin Sampler, which collects falling bulk mate- rial or slurry flow for sampling in primary, secondary, tertiary, and quaternary sampling stages. The fully enclosed units contain a rotating sample collection assembly. They feature access and inspection panels on the top and side to allow for easy viewing of internal components, as well as periodic cleaning. The cutter design incorporates a radial cutter opening cross section so that a full, accurate sample is collected from the material stream. Each sampler also includes a proximity sensor for rotation monitoring purposes. McLanahan | www.mclanahan.com Tensioning system streamlines change-outs Haver and Boecker debuts the patented Ty-Rail quick-tensioning system to allow for faster screen media change-outs. Each package includes two tension rail systems, eight angle boxes, and eight bolts. Once installed, each rail becomes a singular, removable piece since the bolts remain attached to the rail, and the angle boxes remain attached to the vibrating screen. To remove the tension rails, an operator loosens the bolts on each, shifts the angle boxes up, and lifts the rail and bolts out as one piece. This is said to reduce screen media change-out times by about 50 per- cent and can be performed by one person rather than two. Haver and Boecker Canada | www.havercanada.com
