Smaller screener with big-screen attitude
McCloskey International’s versatile R105 High Energy Screener is designed to handle throughput for a large range of rock, quarry, construction & demolition, and soil products. One-third smaller in size than the company’s popular R155, the screener tips the scales at almost 50,700 pounds. The transportable unit features a stockpile height of 11 feet, 9 inches and a screening area of 12 feet by 4 feet, 6 inches.
Longer service intervals, greater operator comfort
Bobcat says its new E80 excavator has a completely new design that sets a high standard by increasing the time between service intervals and improving operator comfort. Daily greasing of the bushings at the boom, arm, and bucket pivot is a thing of the past, says the company, saving the operator 30 minutes per day. The spacious cab includes an operator’s seat that adjusts six ways to create an individually designed ergonomic work environment, and an automotive-style heating/air-conditioning system. A fixed instrument panel on the right side of the cab has an easy-to-read display that provides machine performance information for the operator.
Choose diesel or electric power
Powerscreen’s dual power screen gives users a choice between diesel and electric power. Having this choice provides an option to avoid high fuel costs and addresses environmental concerns about diesel emissions. Once positioned on site and connected to an external electricity source, the unit can be switched to operate on electricity. The track screen retains all the benefits of a mobile machine.
Free-flowing materials feeder
Thayer Scale’s new LWY-SC-RF Loss-in-Weight (LIW) rotary feeder is designed to handle extremely free-flowing and fluidizable materials. The company says the feeder’s design incorporates a rotary feeder that comes in a variety of sizes and configurations, making it ideally suited for applications discharging into pneumatic conveying systems. The feeder system can be configured for either continuous LIW feeding or batching. Weighing is done through Thayer’s patented low-deflection, non-wearing force measurement suspension system flexure scale which measures vertical loading and can take high-load directed overloads.
Bucket tips for mining machines
Caterpillar says its LM Series Ground-Engaging Tools feature a safe, fast, new “hammerless” CapSure tip-retention design. The design allows tip installation and removal by using only a 3/4-inch ratchet. The CapSure retention system makes the pin and retainer integral with the tip. The service technician need only turn the side-mounted locking system 180 degrees, exerting minimal force, to activate the system. Two lifting eyes on top of the tip assembly allow the technician to easily attach a small sling for use with a service crane. The company says, once installed, the new tips, which are constructed of DH3 alloy, are designed to outlast tips constructed of other materials.
Low-cost automation system
Etheridge Automation’s new low-cost Production Plus Automation system was developed to help aggregate plants with limited capital realize the production increases possible with automation. The system is a PLC-based control system that uses the essential production features of the company’s Quarry Information Management System for the operator interface. The system can include five to 20 pieces of operating equipment and up to four crushing circuits. The company guarantees a 10-percent production increase.
Mine monitoring and control system
Caterpillar’s MineStar FleetCommander 3.0 is a comprehensive surface mine monitoring and control system that uses technology to improve productivity and lower costs. Real-time interaction with mobile field equipment allows mine managers to improve machine use, manage operators, track material movement, and monitor production in near real-time. New software supports decision-making by evaluating “what if” impacts of making changes to the production plan during the current shift, helping controllers make decisions that optimize mine productivity.
