17 AGGREGATES MANAGER August 2014 The largest of the E-Series, John Deere's 460E articulated dump truck is equipped with a 481-horsepower Tier 4 interim engine and has a heaped capacity of 33.4 cubic yards. The 50-ton machine is designed for heavy-duty applications and features a ZF transmission with a high-capacity retarder, eight forward gears, and four reverse gears. Responding to customer feedback, the unit is enhanced by on-the-fly differential locks, which can be applied for improved performance in poor conditions. In addition, it comes standard with JDLink Ultimate, which provides operators with 24/7 online access to machine health, utilization, and fuel consumption. John Deere | The Cat 775G Off-Highway Truck delivers a 70-ton payload, improved fuel efficiency, and advanced transmission controls to enhance productivity and drivetrain durabil- ity. Two different economy shift mode selections enable quarry managers to tailor performance to the needs of the business. Advanced control systems also integrate the optional engine compression brake with automatic retarder control to enable faster downhill travel and reduced cycle times. The Cat C27 ACERT engine provides 729 net horsepower and meets Tier 4 final emission requirements. Compared to the previous model, the 775G can hold a higher gear when climbing 10-percent grades. Caterpillar | The Atlas Copco Scooptram ST7 LHD is built for underground applications requiring small size and high performance. The high-visibility FOPS/ROPS-approved cabin is said to put safety first. Easy access to daily service points supports efficient maintenance, and the Atlas Copco Rig Control System enables service information and diagnostics to be logged and displayed on the screen in the cab. Traction control allows full use of the 193-horsepower Cummins diesel engine to fill the 7.5-ton bucket to capacity, which has a 7-foot tramming height. An automatic lubrication system option is available. Atlas Copco | With a transport capacity of up to 33 tons, Liebherr's TA 230 Litronic is configured for maxi- mum work performance. The large dump body, combined with a robust drivetrain, is engineered for efficiency. Impressive retarder performance is said to ensure safe operations, while the unit achieves fast turnover rates with its intelligent drive concept. Maintenance-free bearing points and easy-access service points reduce maintenance costs and downtime. The TA 230 features Liebherr components, including its diesel engine, hydraulic cylinder, ball slewing ring, and elec- tronics. Liebherr says it is ready for the tough operating conditions in quarries and will provide operational reliability and availability. Liebherr | The DuraClass Alumax heavy-duty aluminum dump body is said to offer high strength and low body weight for long life and maximum payloads. Typically up to 50-percent lighter than traditional steel, the decreased body weight of aluminum bodies increases payload capacity and minimizes fuel consumption. The truck features a heavy-duty, 8-inch extruded top rail that resists bowing from heavy internal loads. The bottom rail, which includes an inside radius for faster and cleaner dumping, ties the deck, sides, cross members, vertical posts, and outside dirt shedders together and enhances structural integrity. Aluminum 5 3/4-inch I-beam long members have an integrated rubber track and rubber riser to reduce shock and noise. The 4-inch stacked U-shaped cross members provide extra load-bearing vertical walls.
