TOP ROLLOUTS CATERPILLAR INC. Tier 4 Final haul truck Caterpillar says its new Tier 4 Final 777G off-highway truck offers next generation transmission control with its Advanced Productivity Electronic Control Strategy (APECS), which provides greater productivity at better fuel rates with torque shift man- agement that allows the truck to carry more momentum up grades. The engine requires the use of ultra-low sulfur diesel fuel and low-ash engine oil, but requires no additional maintenance or operator input. Additional features include enhanced braking and trac- tion control, hydraulic oil-immersed disc brakes, a traction control system that differen- tiates between tire spin and high-speed turns, wider cab access with hand rails, 50-percent lower noise levels in the cab, and a combination of radar and cameras for enhanced safety and object detection. Maintenance is said to be quick and convenient with ground-level service centers for both electrical connections and fluid fill. Caterpillar, Inc.; cat.com/requestcatinfo.

Portable frac sand plant Cemco and McLanahan collaborated to produce the industry's first por- table frac sand plant capable of producing two sizes of frac sand. The com- pany says the plant transports easily from one site to the next, is highway legal, and meets all state DOT requirements for transport. The plant design features two units on separate chassis to keep it within the legally transport- able height of 13.5 feet. The two units connect with four hoses to make a complete, integrated plant. Only two operators are needed to assemble and disassemble the plant, which is said to take less than eight hours. The self-erecting plant offers an average output of 150 tons per hour, and is built for continuous operation. A one-touch screen control panel regulates and determines the operation and characteristic of the entire plant. The electric-powered plant is designed with minimal moving parts to minimize maintenance and downtime. Cemco, Inc.; cemcoturbo.com. McLanahan Corp.; mclanahan.com.

Near-zero emissions Cummins says its QSL9 engine, with up to 400-horsepower output, meets Tier 4 Final near-zero emissions standards with a next-generation compact catalyst and selective catalytic reduction (CCC- SCR) after-treatment system. The company says the engine makes no performance compromises in order to meet the standard, retaining its proven fast engine response and reliability. The after- treatment system provides a fully passive, flow-through operation and enables the engine to further improve fuel efficiency over the current engine. Further, it is configured for a highly compact and flexible equipment installation. The CCC-SCR after-treatment will be available in multiple configura- tions, including switchback, horizontal, and vertical. Cummins, Inc.; cummins.com.

Ultra-fines recovery system Deister's new ultra-fines recovery system (UFR) is designed to recover ultra-fine sands and silts, allowing operations to eliminate or greatly reduce the use of settling ponds. The system enables producers to create a dry tailing or silt product for stockpiling for removal or as a saleable prod- uct. It is capable of recoveries to 350-400 mesh at feed capacities from 1,500 to 3,500 gallons per minute. The reverse-slope vibrating screen is available in sizes up to 7 feet wide and 12 feet long with solids capacities of up to 70 tons per hour. Victaulic connections allow flexibility and ease of maintenance. A sloped bottom plate promotes even solids flow to the pump inlet, and an auto- matically adjusted make-up water valve protects the pump. A hand-railed stairway and platform on both sides and back of the screen allow safe and easy maintenance access. Deister Machine Co.; deistermachine.com.
