IRock: RDS-20
IRock says the RDS-20 primary crusher is versatile enough for use across multiple industries, having the ability to process materials like quarry rock, demolition debris, recycled concrete, recycled asphalt and base rock for oil fields. The machine features a 5-ft. x 16-ft. double-deck screen. It has the ability to crush, screen and separate up to three different sizes of materials – two sized and one crusher run – at a rate of up to 500 tph. The initial vibrating feed opening is 52 in. x 17 ft., while the crusher feed opening is 56 in. x 32 in. A closed-circuit design allows both decks of oversized material to return to the feeder for another pass through the crusher after the initial round of screening. A 440-hp Cat C-13 ACERT Tier 3 engine powers the RDS-20, which can also be equipped with a Tier 4 engine. www.irockcrushers.com Photo: IRock Crushers Keep Reading
Doosan: DX420LC-3
The DX420LC-3 excavator has been upgraded with improved engine horsepower, lift capacity and cooling capabilities, according to Doosan. With an operating weight of 92,374 lbs., a maximum digging depth of 25 ft., 5 in., a dump height of 25 ft., 4 in. and maximum digging reach of 37 ft., the DX420LC-3 is capable of handling a variety of applications. A six-cylinder, 362-hp, water-cooled diesel engine powers the excavator. Doosan says the engine has been optimized for use with a cooled exhaust gas recirculation system, a diesel oxidation catalyst and a diesel particulate filter. The turbocharged engine features a high-pressure common-rail design with direct fuel injection, electronic control and four valves per cylinder. www.doosanequipment.com Photo: Doosan Keep Reading
Telsmith: T300 Cone Crusher
Telsmith's T300 Cone Crusher is engineered for maximum uptime and productivity while delivering 300-hp performance and an estimated crushing capacity output between 135 and 440 tph in quarry applications. The T300 features a large clearing circuit, which is engineered to safely and quickly allow any uncrushable materials to pass. For reduced maintenance time and costs, the T300 is designed with six cylinders yet still offers a large crushing force, Telsmith says. The unit also offers an anti-spin feature that prevents head spin to extend manganese life. Like other key components, the T300 is mounted on top of the machine to offer top-service access. The T300 is also designed to operate with pressure lubrication oil while eliminating the use of a gearbox and a separate hydraulic circuit. www.telsmith.com Photo: Telsmith Keep Reading
SKF: System 24 LAGD Series
SKF System 24 LAGD Series single-point automatic lubricators are timely and accurate hands-off solutions to deliver the proper preset amount of lubricant needed for bearings in machinery, according to the company. The gas-driven feed versions are engineered to perform reliably on a 24-hour basis without manual intervention, and they can resolve issues typically associated with hard-to-access or potentially hazardous lubrication points. Ultimately, SKF says the lubricators optimize the accuracy, reliability and cleanliness of lubricant delivery, contributing to increased uptime of assets, reduced maintenance and a favorable environmental impact. Lubricators feature flexible and user-adjustable dispense settings (ranging up to 12 months) and transparent lubricant containers for visual inspection of dispense rate. www.skf.com Keep Reading
Rugby Manufacturing: Eliminator LP
Rugby Manufacturing's redesigned Eliminator LP dump bodies line is available in carbon steel, aluminum and stainless steel construction in 9-ft. and 11-ft. lengths with interchangeable parts. A 12-ft. model is available in carbon steel and aluminum. The steel model now features a seamless, one-piece 10-gauge steel floor for optimum strength and durability. A lower mounting height improves stability on all models, Rugby adds, while a 9-ft. inside diameter allows for full sheets of plywood or other materials. Each model is available with fold-down sides and features Rugby’s EZ-Latch upper-tailgate mechanism, which releases the tailgate quickly and keeps it more secure when closed. www.rugbymfg.com Keep Reading
Atlas Copco: Hütte HBR 202
Hütte Bohrtechnik's self-contained hydraulic crawler drill rig model is available with an onboard electric or diesel motor, meaning it does not need a separate power supply. The Hütte HBR 202, which is available exclusively through Atlas Copco, shares the same undercarriage and telescoping mast as the 203. Those two areas are where the similarities between the 202 and 203 end, though. The HBR 202 features unique kinematics resulting from an upper structure that rotates 140 degrees left and right and extends forward and back about 14 in. An addition is a three-speed Hütte HG28 low-profile rotary head that provides 21,000 ft.-lbs. of torque with a clearance to the front face of less than 12 in. www.atlascopco.us Keep Reading
Martin Engineering: EVO High Speed Impact Cradle
A new high-speed impact cradle from Martin Engineering is designed to reduce roller and frame damage from heavy conveyor loading conditions in aggregates, mining, coal handling and other applications involving dense materials and/or high volumes. The EVO High Speed Impact Cradle is engineered to withstand brutal operating conditions, reducing roller failures and service requirements, says the company. The new cradles use Martin Engineering’s Trac-Mount technology to slide in and out easily for maintenance. The modular components are light enough to be removed by hand, without using a crane or other equipment to handle them. www.martin-eng.com Keep Reading
Terex Minerals Processing Systems: MACS
MACS (Mobile Aggregate Crushing System) plants utilize larger crushers and screens than what's typically used in track-mounted or wheeled plants, according to Terex. Now, MACS offers the MVP450X cone crusher, which is configured with a number of features to increase productivity and ease of use, the company says. Enhancements include high-speed clearing of jammed material and quicker crusher separation capabilities for faster manganese changes, Terex says. The units travel at less than 13 ft., 6 in. high and at less than 12 ft. wide. Interplant conveyors are designed into the units so separate transfer conveyors are not required. Folding conveyors and walkways set up using on-board hydraulics, eliminating the need for cranes or lifts. www.terex.com Keep Reading
Powerscreen: XH320X
The XH320X represents the next generation of Powerscreen's impact crushers for the quarrying and recycling markets. This impact crusher was developed to incorporate an independent hydraulically driven pre-screen that's designed to improve fines removal and reduce chamber wear costs for users. Coinciding with the pre-screen feature is a hydraulically folding extended side conveyor with a stockpile height of 12 ft., 1 in. The hopper capacity has also been increased with the addition of hopper extensions that can be hydraulically folded for transport. The new hopper design incorporates hydraulic locking pins for rapid setup time, removing the need for manual wedges. An extended hydraulically folding product conveyor that increases the stockpile height to 13 ft., 1 in. is an option. www.powerscreen.com Keep Reading
