Versatile portable impact plant
McCloskey International’s new I44R combines an impactor with a screenbox and a recirculating conveyor system to create a full crushing, screening, and recirculating system. The machine is powered by a 350-horsepower Cat C9 engine and boasts a 9.8-cubic-yard capacity in a 42- x 43-inch-wide impactor. The 5- x 10-foot screenbox features the company’s High Energy technology, a 10-millimeter throw pattern, and direct hydraulic drive. A heavy-duty, three-ply, chevron-pattern belt returns oversize material to the feeder.
The unit is said to be easy to move from site to site and can be operational in a matter of minutes with its folding hoppers and conveyors. Transport dimensions are 11 feet, 2 inches high; 50 feet, 4 inches long; 10 feet, 1 inch wide; and a weight of 94,300 pounds. An open chassis design allows for easy maintenance access. Additional options include a water pump and dust-suppression system, as well as a refueling pump.
Made in the U.S.A.
McLanahan Corp. launched a new line of filter presses designed, manufactured, and serviced in the United States. The fully automatic systems provide a fines dewatering solution that eliminates the need for slurry ponds and a full-time operator. Several different options are available in both overhead-beam and side-beam design with either recessed-chamber filter plates or membrane filter plates and a wide range of pressures from 225 to 725 pounds per square inch. Other options include core blow systems and automatic wash systems.
LiuGong Machinery Co. says its 922E next generation crawler excavator features additional power and control, a 5-percent improvement in operating efficiencies, and an 8-percent reduction in fuel consumption. The machine’s Intelligent Power Control System increases digging force by up to 10 percent for 10-second intervals. The no-time-limit heavy-lift system enables the operator to increase pressure to build force and reduce hydraulic flow to the attachment, while reducing speed. An automatic boom-descent regeneration system allows the boom to descend faster. A multi-working-mode selection system gives the operator the ability to match performance with the job. The excavator is powered by a Cummins QSB6.7 diesel engine rated at 127 kW.
Versatile, lightweight, and fast
Hyundai Construction Equipment Americas Inc. says its new HL730-9 wheel loader is the smallest, lightest, and most nimble of its new 9-series, boasting a 9.2-second cycle time. The machine is powered by a Cummins Tier-III QSB4.5 engine with three engine modes. The loader is equipped with long-life hydraulic filters with 1,000-hour service intervals and Hyundai certified hydraulic oil said to last up to 5,000 hours before changing. The company’s Hi-Mate Remote Management System provides operators and service personnel access to vital service and diagnostic information via an online portal.
Improved mobility, flexibility
Powerscreen, a Terex company, says its new Warrior 1400X portable screen was designed with reduced engine running speed, enhanced hydraulics, and a reduction in fuel consumption of up to 15 percent in comparison to its predecessor. Other key achievements include improved versatility and design specifications, improved mobility with a two-speed tracking system as standard, and a screening-angle range widening of 13 to 19 inches. Standard stockpiling capacity on all conveyors has increased by up to 25 percent. The time required for set-up and shutdown is faster than the previous model. Serviceability features include a screen box raise function and the ability to raise the collection conveyor. The chute design, in combination with the new feeder under-tray, slide-out feature, is said to minimize potential spillage and reduce harmful material buildup around the machine.
W.S. Tyler says its XL-Class vibrating screen combines advanced exciter drive technology with a wide body to offer better screening action and more throughput. Larger than the company’s other screens, the XL-Class is intended for high-tonnage production rates, yet is designed for low maintenance and easy operation. The screen offers a large 390-square-foot screening surface, allowing it to replace up to two inclined screens. This enables it to handle production rates up to 15,000 tons per hour and cut sizes from 1/4 to 5 inches with varying degrees of incline. The unit can also be configured as a banana screen. The decks are sloped to increase the speed of the material flow, which is especially effective when the feed load contains large amounts of fines smaller than the opening of the screen media. The screens are engineered using finite element analysis, which detects high vibration and stress points, natural frequencies, and harmonic responses, allowing each screen’s stroke, speed, and other variables to be set to perform at peak efficiency.
More environmentally friendly engine
Komatsu America Corp. says its new PC210LC-10 hydraulic excavator features a more environmentally friendly Tier 4 Interim-certified Komatsu SAA6D107E-2 engine. The excavator has an operating weight of 52,036 pounds and features improved hydraulic efficiency and operator comfort. The machine features improved hydraulic efficiency and has two counterweight options that maintain the lift capacity and stability while providing transportation flexibility. KomatsuCare and KOMTRAX come standard with the machine.
Minimizes rollover issues
Felling Trailers says its new X55 Cross/Over Dump trailer handles materials that current bottom dumps cannot haul. The trailer maintains 70 percent of carried weight over its chassis and is designed to minimize rollover issues experienced in side-dump and end-dump trailers. The company says the trailer doesn’t have to stop like other side dumps or end dumps, but can dump on the move and at a higher speed. Because of the weight distribution, the operator doesn’t see torque in the king pin or see/feel movement in the tractor while dumping. The trailer can dump at 55 degrees and is capable of dumping product that could stick in other trailers.
Multiple options, versatility
The hauler chassis from Volvo Construction Equipment can be fitted with a wide range of superstructures, providing an endless range of applications. The hauler chassis is a modular concept whereby customers can order a standard articulated hauler, supplied without load body or hoist cylinders. Customers can then modify these base machines to suit the specific transport solution required. A bolt-on frame extension is available for the A25F and A30F machines for added flexibility. The extensions are offered in two lengths — 47 inch and 67 inch — to support longer or larger volumes.
Increased production capability
In response to requests from operators, Hitachi added a number of improvements to its EX5600-6 ultra-large hydraulic excavator. The machine is heavier, with more engine horsepower, and the loader bucket capacity has been increased from 35.5 cubic yards to 38 cubic yards. The BE-backhoe version capacity has been increased from 38 cubic yards to 44.5 cubic yards, and the reach of the backhoe front attachment has been shortened. Hydraulic pump output has been increased by 10 percent without degrading conventional cycle-time performance, resulting in a higher flow rate at the same pressure. The machine is offered in both backhoe and loader shovel configurations.
Flexco says its new MHP Precleaner, recently added to its line of heavy-duty belt cleaners, features the largest, most abrasion-resistant urethane blade offered by the company. Multiple material path options and extended pole lengths ensure the cleaner fits each application perfectly. The large blade provides an extended life so the cleaner can run longer and more efficiently. A faceted profile design with continuous blade-edge renewal improves cleaning efficiency throughout the life of the blade. The molded-in wear line on the MegaShear blades makes routine visual maintenance checks easy. The three-piece pole design provides additional strength. Dual tensioners come standard for both spring and air/nitrogen systems.
New choice in ticket printing
Rice Lake says its new TicketPress offers a new choice in scale ticket printing. Its sleek, contemporary layout features a straightforward operator keypad and display. The unit gathers data from weight indicators, PCs, and more for on-command, formatable, dot-matrix printing of up to five-part, multi-copy forms. It is designed to integrate with old and new scale applications with features such as battery-backed time and date, sequential ticket numbering, automatic media thickness adjustment, and a quick-change ink cartridge.
Automatic initial priming/re-priming
Thompson Pump and Manufacturing Co., Inc. says its new 6-inch, portable, high-head 6JCC pump delivers 1,100 gallons-per-minute high heads to 490 feet and 212 pounds per square inch. The pump offers the company’s exclusive Enviroprime System, which provides reliable, automatic initial priming and re-priming with the environmental advantage of not spilling pump fluids during operation. Additional options include the company’s Silent Knight sound-attenuated canopy, accessories, applications assistance, and more.
