Komatsu America Corp. says its new PC160LC-8 hydraulic excavator delivers maximum digging force, low noise level, and excellent fuel economy. The excavator has an operating weight of 36,770 to 37,740 pounds and is powered by a Komatsu SAA4D107E-1 engine. Its electronically controlled high-pressure common rail, fuel-injection system is EPA Tier 3-emissions certified.
Equipped with the latest Komtrax fleet monitoring system and wireless technology, the excavator’s operating data — operating hours, location, cautions, and maintenance alerts — are sent to a secure Web site for analysis.
Special features include the following:
• Large 7-inch LCD monitor that displays data;
• Easy service and maintenance access and Komatsu’s Equipment Management Monitoring System;
• Reliable, exclusively designed frame and electronic components;
• Five working modes designed to match engine speed, pump flow, and system pressure to specific application requirements with one-touch Power Max control to increase digging force by 7 percent for 8 seconds when additional digging power is needed; and
• A wide, spacious cab with a high-back seat for reduced operator fatigue.
Atlas Copco’s new HB 3100 hydraulic breaker has a service weight of 6,944 pounds and is suitable for carriers in the 66,139- to 114,640-pound class. Features include the Vibro-Silenced System to reduce noise and vibration, AutoControl to adapt blow frequency and impact energy to hardness of the rock, and the ContiLube II automatic lubrication system. StartSelect allows the operator to choose the startup and shutdown process to match the application. The PowerAdapt system shuts down the breaker when oil pressure exceeds the maximum input value, while an improved box system provides better stability and resistance. An optional DustProtector two-stage seal system protects the hammer unit and bushings from dust and rock particles in the lower part of the breaker.
Boart Longyear says its new flyable SC11 surface drill rig is the only compact and modular rig in its class that offers 5,456 Nm of torque and can manage PQ-size rods. The drill rig delivers large-diameter, deep-hole drilling with a 132 kN pullback rating and features a variable-speed motor. The rig was designed to easily break down into flyable modules, with the heaviest lift being only 680 kilograms. Lifting points are positioned at the module’s center of gravity for balance. Quick-connect hydraulic couplings accelerate assembly/disassembly and prevent oil spills.
Atlas Copco says its new ROC T35M drill rig features the COP 1840 rock drill with 18 kW of drilling power to drill holes ranging from 2.5 to 4 inches in diameter to a depth of 82 feet. Powered by a Cummins QSB 6.7 Tier III engine rated at 190 horsepower and 2,300 revolutions per minute, the rig matches percussion power and feed to the rock. The unit features a carousel with rocker switch rotation and single joystick control. The carousel can handle up to six, 12-foot rods plus a 14-foot starter rod.
Leica Geosystems says its next-generation, cutting-edge, Leica PowerDigger 3D guidance system for excavators is the result of many years of experience in developing machine-control systems. Its PowerSnap concept allows users to seamlessly swap the panels between laser, slope, and three-dimensional machine control as the job demands. The control panel has a rugged housing and is equipped with a 7-inch, full-color touch screen that takes the user through the installation, setup, and operating modes at a glance. The system also features built-in dredging and volume calculations.
Doran Manufacturing says its new Doran 360CE tire pressure monitoring system is designed for use with commercial equipment used in mining, construction, and earth moving applications. Installation and programming of the digital LCD display and valve-mounted sensors can be accomplished in less than an hour and require no special tools. The in-cab display system provides real-time monitoring for up to 36 wheel positions.
The Core Systems Design program from Superior Industries offers drive- and tail-pulley assemblies custom-engineered for a specific application. Each assembly is delivered as a pre-assembled package, which eliminates assembly cost and reduces installment time. The shaft on each assembly is protected by a specially developed rust prevention treatment.
John Deere Power Systems’ PowerTech PVX 9.0L and PowerTech PSX 9.0L engine models are the first of their off-highway 75-horsepower and above engines to be certified by the Environmental Protection Agency and European Union as compliant with Interim Tier 4 and Stage III B regulations.
Durable mining tire
Titan Tire Corp. says its second generation 007 MFT mining tire features a new belt package that provides a more durable design through changes to the compounds in the tread and base, which help reduce overall heat generation and improve cut, chip, and wear characteristics. The steel was removed from the sidewalls to provide better durability.
Baldor Electric Co. says its Super-E Duty Master motors, available in TEFC and WPII (weather protected) foot-mounted configurations, are designed for protection against extreme environmental conditions. Stock motors are available in 3,600, 1,800, and 1,200 revolutions per minute and 200 through 1,500 horsepower.
All KPI-JCI track-mounted impactor plants now come with the Mobile Star equipment monitoring system. The system allows any computer with an Internet connection to remotely monitor the location and operations of any of its Fast Trax equipment. It also has the ability to send e-mail notifications of operational events and logs the events for future reference and troubleshooting.
Loadrite says its new L-Series 2160 Advanced Payload Scale (APS) for Deere K-Series four-wheel-drive loaders extends the functionality offered by the loader’s embedded payload scale option. The APS features an easy-to-use, icon-driven interface and extensive data-collection and reporting capabilities.
Synthetic heavy-duty engine oil
Petro-Canada’s new Duron-E Synthetic 5W-40 Heavy Duty Engine Oil is specially formulated for both on- and off-highway fleets and is licensed to the latest API Heavy Duty Engine Oil category. The company says the oil extends drain intervals (along with an effective maintenance program), reduces engine wear, minimizes oxidative thickening, provides corrosion protection, and provides optimal top-up and cold start-up performance.
Chute improves conveyor loading
Custom-engineered Inertial Flow Transfer Chutes from Martin Engineering help control material delivery from the time it leaves the conveyor discharge pulley until it reaches the receiving belt. The chutes minimize impact and wear on liners and belts, while containing dust and spillage. Each chute design is tailored to suit the specific material characteristics and conveyor systems.
