Aggregates Manager’s Top 25 RollOuts for 2008
Fintec unveiled a new track-mounted impactor that combines its expertise in designing track-mounted mobile crushers with the impact-crusher expertise of its new parent company, Sandvik. The new 1440 features a Sandvik PR301D impactor with a fluid clutch drive and a 440-horsepower engine. Fed by a two-deck pre-screen, the crusher is a four-hammer, open-style rotor. The unit has an operating weight of 49.8 metric tons and is about 51 feet long. It is designed for throughputs of 300 to 350 metric tons per hour.
Long-lasting fine wire
W.S. Tyler introduced Ty-Ger Wire, a high-carbon industrial wire available for high-wear screening application. The company says this hard steel wire was traditionally available only in larger diameters, but it has developed a patented process to create a small diameter wire that is high-wear, tear-resistant, and extremely elastic. The company says Ty-Ger Wire has up to two times the tensile strength of stainless steel and up to four times the strength of basic steel.
Efficient cone crusher
Metso Minerals rolled out its new cone crusher, the Nordberg HP5. The second in an all-new series of high-performance cones, it is designed to offer efficient production of high-quality end products. The HP5 is said to produce much finer products with fewer crushing stages, thereby saving energy and lowering costs. With a combination of optimized speed and a large throw, the company says the unit offers the highest reduction ratios of any cone crusher currently on the market. Its efficient crushing action improves power consumption, resulting in a lower kilowatt-hour per ton of crushed end product with lower recirculation load, according to Metso.
Streamlined installation tool
Flexco introduced its improved aluminum MSRT installation tool designed for the company’s SR Fastening System. The Aluminum MSRT Multiple Rivet Driving Tool is lightweight, portable, and designed to assist the splice installer in harsh working environments where heavy splicing equipment has to be moved regularly. The scalloped design of the new tool’s riser plate is said to allow for fast, accurate alignment of fastener strips on the anvil plate.
Caterpillar introduced its new 740 articulated hauler with expanded capacity, touting its 43.5-ton payload capacity as the highest in the class. Its expanded capacity truck body handles up to 31.4 cubic yards of material. Other features on the truck include differential locks that can be engaged and disengaged on the go for faster cycle times in poor underfoot conditions and steep grades, a 453-horsepower engine, and a seven-speed automatic transmission with individual clutch modulation to ensure constant shift times even when the oil is cold.
Highway portable stacker
Thor Global introduced its T150-20, a 48-inch by 150-foot highway-portable telescopic stacker. The unit can be folded up and ready for transport or unfolded and ready for production within 15 minutes, the company says, and can stockpile up to 2,000 tons per hour. The new stacker features a quick-release system that allows the operator to engage or disengage the radial drive system within three minutes. It also boasts zero-speed switches on inner and outer conveyors to protect the stacker from overloading if the belt is broken or slips.
All weather, automated drill rig
Atlas Copco highlighted its ROC D7C, a silenced SmartRig surface crawler. SmartRig is a concept that facilitates a variety of automation in drill rigs. The hardware is designed to operate in every possible weather condition, and the software can be upgraded on site. The units have built-in logging and monitoring functions as well as support for diagnostics and fault finding. Through PC software, the SmartRig control system electrical signals are generated to control the hydraulic valves. This concept of a “dry cab” has no hydraulic pipes or gauges and reduces noise for the operator.
