October 2008 – RollOuts
Innovative housing and rotor
Stedman says its new, patent-pending V-Slam VS-88 vertical shaft impactor features innovative housing and rotor designs; an easy-access low-profile split-swing lid; higher operating speed for finer grinding; and capacities up to 500 tons per hour.
Dewaters plant sludge
McLanahan Corp. has obtained exclusive rights to market Matec Machinery’s HPT Plate and Frame Filter Press in the Americas. The company says Matec’s use of high pressure technology (HTP) allows the press to work at pressures of up to 300 pounds per square inch and handle even the most difficult, high-clay-content sludge. The Matec Press is said to function without use of flocculants and does not require a full-time operator to monitor feed density, flocculant dosage, or belt conditions. McLanahan says the unit also eliminates the need for settling ponds.
Bigger track-mobile plant
Telsmith has expanded its QuarryTrax line of track-mobile crushing plants with the introduction of the T16060, a primary impact plant designed for high-capacity production up to 800 tons per hour. The plant features Telsmith’s PA6060 primary impact crusher, which boasts a massive solid rotor set on oversized 220 millimeter, wide-series bearings. The large rotor allows the unit to crush 40-inch stone or concrete slabs.
Compact portable plant
Pump Vacuum Systems has developed a different way to produce sand and gravel using the company’s PVS Jet Pump. It created a portable plant that can produce multiple products while washing the material. The plant uses a grizzly screen to remove oversize, then moves sized material into the pump, where it is washed and conveyed either to a de-sander or a velocity box, then separated into final products. The company says its first plant is producing 300 tons per hour using one wheel loader to charge the plant and load trucks.
Self-dumping dust collector
Farr Air Pollution Control has introduced a new self-dumping hopper that simplifies the disposal of dust captured by cartridge-style dust collection systems. Farr says the hopper, available in one or two cubic-yard capacities, is easier to use than conventional barrels or collection drums and is recommended for a full range of dry mists, including those that must be reclaimed or recycled after the collection process.
New vibrating screen
W.S. Tyler has rolled out its new TYCAN HSG T0Class vibrating screen which allows the stroke and amplitude of the vibration to be adapted to product requirements quickly and easily, without new parts. The company says its new technology allows screen media to be “easily blended, modified, and exchanged, optimizing wear life versus open area.”
New 3-yard loader
Komatsu has unveiled the Dash-6 version of its 3.25-cubic-yard WA320PZ-6 wheel loader. The 32,480-pound machine has a 167-horswepower, Tier 3 engine and comes standard with Komatsu’s fleet monitoring system which relays machine operating data to a secure Web site for tracking. The Dash-6 also offers a new parallel linkage loader arm design for enhanced efficiency in fork applications. Its new cab is pressurized and quiet – the company says noise levels have been reduced to 70 dBA.
Three new excavators
Case Construction Equipment has added three more excavators to its CX B Series: the 79,065-pound CX350B, the 103,800-pound CX470B, and the 153,400-pound CX700B. The machines get Tier 3 engines with common rail fuel injection that deliver up to 7 percent greater fuel efficiency than previous models. They also get more hydraulic horsepower and larger-diameter hydraulic cylinders. The CX350B and CX700B now feature regenerative hydraulics on the boom and arm, as well as the bucket curl, speeding digging cycle times.
Lippmann-Milwaukee is touting its new 5062 jaw crusher as a replacement for a gyratory primary crushing station, describing it as a “massive,” high-capacity unit designed to hold up in the most demanding hard rock mining operations. Lippmann says that for the price of one gyratory installation, aggregate processors are successfully installing two of 5062 Jaws.
More powerful drill string
Rockmore says it developed the new XR32 thread design to provide underground drillers with a stronger, more powerful drill string. The XR32 connection is said to provide stability at the thread end, reducing stress on the thread connection. Its design provides stronger rod support, increased rigidity, and added strength to minimize rod bending due to complex rock formations or uneven surfaces.
Loader training simulator
Simlog has introduced what it says is the world’s first PC-based wheel loader simulator for training quarry and mine operators. The simulator puts trainees at the controls of modern loader and includes digging and interaction with a simulated off-highway truck. It is designed for skills assessment, skills development, and refresher training for both new and veteran operators.
Biodiesel blends approved
Case Construction Equipment has approved the use of B20 blends (20 percent biodiesel, 80 percent petroleum diesel) for most of its construction machinery. The company approved B5 blends in 2006. Case has published a chart matching its models and engines to current biodiesel recommendations.
Impactor gets new features
Stedman has added two new features to its Grand Slam secondary horizontal shaft impactor. The new Crush Plus grinding path system creates a third crushing chamber to maximize one-pass product yield, minimize oversize, improve material soundness, and produce highly cubical product. The Max-Yield automated apron adjustment system maintains gap setting adjustment for aprons and the grinding path, improving one-pass yield and reducing changeover downtime.
Production-boosting roller bearings
Emerson Industrial describes its new Sealmaster Mounted Spherical Roller Bearing as an advanced, double-row design that improves load capacity and speed capabilities in aggregate conveyor operations. The bearings feature pillow blocks that contain high-capacity, double-row spherical roller bearings designed to carry high radial and combination loads. The series is said to have a higher basic dynamic rating (BDR) than competing models with a similar cartridge design.
Ruggedized time-clock system
TimePilot has rolled out a time and attendance system designed from the ground up for construction-related applications. The weatherproof design can be mounted on walls, posts, or the side of a truck. Employees clock in and out by touching a key-sized iButton to the clock. The clock reads the iButton, identifies the employee, and records the time.
Smaller, updated screen
Powerscreen has developed the H5163R scalping and screening plant as a smaller, updated version of the 6203 plant introduced earlier. The new unit can handle materials up to 10 inches and produce up to 600 tons per hour of high-specification products.
New mining truck
Caterpillar has issued the D-series version of its 785 mining truck. The new 785D can be configured for payloads ranging from 142 to 155 tons. It has a 1,248 net horsepower, Tier 2 engine and can operate at altitudes of 14,000 feet with no derate. The 785D also features Cat’s “X body,” which includes greater volume capacity and mine-specific options.
New filling scales
Intercomp says its new filling scales are designed to weigh empty trailers at the point of filling and can accommodate a variety of trailer lengths, wheel configurations, and axle spacings. The modular, portable scales offer a total capacity of 120,000 pounds.
Reznor has introduced a pair of new, 250,000-btu waste-oil heaters. Designed to recycle used oils into shop heat, the RA-250 is a standard unit space heater, while the RAD-250 is a ductable furnace, designed to duct heat wherever it is needed.
More flexibility, capacity
Atlas Copco has redesigned its ROC L8RC drill rig to increase its performance and versatility. Able to drill blast holes or dewatering holes, the ROC L8RC can be converted from down-the-hole drilling to reverse-circulation (RC) drilling; RC mode is used for efficient in-pit drill grade control or shallow exploration holes, according to the company.
Indeco says its new HP 25000 is the world’s largest hydraulic breaker. The 24,370-pound unit measures more than 14 feet high and has a 10-inch tool diameter. It can strike up to 460 blows per minute.
MTi Group says its new Solo BlastBag borehole plugs are designed to be deployed with one hand. The product features a patented two-speed aerosol latch that works in all temperatures.
Caterpillar Inc. and Navistar International have signed a deal to jointly pursue highway truck opportunities world wide, including severe service trucks for North America. Cat hopes to roll out a Cat-branded on-highway truck in 2010.
ESCO has added two new eco-friendly formulas to its line of crusher backing products: ECO-BAK Standard is for standard crushing applications, and ECO-BAC High Impact is for more severe applications.
Detroit Diesel has introduced the DD13, a 12.8-liter, six-cylinder diesel engine for the vocational markets, among others. The engine can develop 350 to 450 horsepower, depending on configuration.
Sterling Trucks is now offering a brochure for its Class 7-8 natural gas truck on-line at www.SterlingTrucks.com/NaturalGas.
More power and lift
Caterpillar has given its new 315D L excavator 5 percent more horsepower and up to 8 percent more lift capacity than its predecessor. Along with a new Tier 3 engine, the 115-horsepower, 38,095-pound machine is factory-equipped for fast installation of auxiliary hydraulic circuits, and its control system stores hydraulic flow and pressure for up to 10 different work tools.
‘Promising’ hybrid research
Volvo Construction Equipment is touting new research that shows diesel-electric hybrid technology can reduce fuel consumption and CO2 emissions by greater amounts than previously thought.
“We are facing the very real prospect of fuel savings up to 50 percent, significant performance increases, and a reduction in CO2 emissions in the order of millions of tons a year,” Volvo CE’s Arvid Rinaldo told Aggregates Manager’s Kirk Landers and a group of international business journalists in June.
Volvo unveiled its L220F Hybrid last March, projecting fuel savings of up to 10 percent depending on application. Further product development has improved fuel usage even more – in particular, an integrated starter generator that allows the engine to switch off when the machine is motionless and instantly switch on when the engine is needed. Volvo expects to begin deliveries of the L22F Hybrid late next year.
Indeco is replacing its UP-series breaker line with the new HP series, which boasts increased hydraulic efficiency across the line. The company has also introduced innovations specific to each size class, including a slimmer, lighter casing for mini breakers.
Atlas Copco has completed its line of medium-duty hydraulic breakers with the introduction of the 3,310-pound MB 1500. Suitable for carriers in the 17-29 metric ton weight class, the new model has fewer moving parts than previous generations and a control system that automatically adapts blow frequency and power output to operating conditions.
