How we made our choices
When we ask readers how we can best help them keep track of changes in the products and services they use to produce aggregates, almost everyone wants an annual short list of the really important stuff.
No wonder. The sheer volume of introductions is overwhelming. Aggregates Manager covers dozens of products each year in its RollOuts departments and Supply Lines features.
So each year, our staff reviews all the product introductions we’ve covered for the past year (our Top RollOuts “year” actually runs from the December 2009 issue through the November 2010 issue) to pick out 25 that we believe are worth further review. Our priorities are new concept products — which are rare — new series/new generation products in categories that relate to the aggregates industry, and other rollouts which serve our readers’ interests by increasing competition in a product category.
Inevitably, we omit deserving products, either because we just didn’t understand the significance of the product or because the announcing company didn’t communicate what was special about the product, or both. In either case, we apologize in advance for these omissions.
Breaker with improved box design
Atlas Copco’s new HB 3100 hydraulic breaker has a service weight of 6,944 pounds and fits carriers in the 66,139- to 114,640-pound class. Features include the VibroSilenced System for reduced noise and vibration, AutoControl that adapts blow frequency and impact energy to the hardness of the rock, the ContiLube II automatic lubrication system, StartSelect that matches the start up and shut down process to the application, the PowerAdapt system that shuts down the breaker when oil pressure exceeds the maximum input value, and an improved box system for better stability and resistance.
Large crawler excavator
Doosan’s new 72.1-metric-ton DX700LC crawler excavator features an operating weight of 158,953 pounds with standard boom and arm and a 4.32-cubic-yard bucket.

Each wire is said to vibrate independently to provide a harmonic frequency that reduces plugging and blinding, improving throughput performance by as much as 30 percent. The company says the screens perform well when screening dry material, but are especially productive when handling wet or sticky material. The screens are available in three styles.
Washes aggregate using less water
W.S. Tyler says its new Hydro-Clean washing units clean aggregate while reducing water consumption by up to 75 percent over traditional log washers. The units use high-pressure nozzles rotating at 90 revolutions per minute to spray up to 90-percent recycled water on material with pressures up to 2,900 pounds per square inch, removing silt and clay particles as small as 63 microns and processing up to 400 tons per hour, depending on model size and application. Water consumption ranges from 27 to 211 gallons per minute, depending on application and model size; power requirements are no higher than 300 horsepower (225 kW) on the largest model. The units are available in four model sizes that produce 20 to 400 tons per hour.
Updated loader/backhoe line
Case’s new 590 Super N, the largest loader/backhoe in the company’s N Series, features a 108-horsepower, 4.5-liter, turbocharged engine. The company describes the N Series as “stronger everywhere,” touting increases in backhoe breakout force and lift, along with increased loader breakout force, lift, and reach. A new Power Lift system is said to channel hydraulic power directly to the boom, increasing lift capacity by as much as 39 percent. Three transmissions are available — Powershift S-Type, Powershift H-Type, and Powershuttle. New side lighting illuminates the entire perimeter of the machine.

The machine also features a GPS-capable satellite system (Hi-Mate) that monitors machine functions, fuel efficiency, and diagnostics through an online portal.
Hybrid excavators come to North America
Komatsu’s 138-horsepower, 20- to 22-ton PC200LC-8 hybrid excavator has an operating weight of 43,643 to 47,260 pounds and a bucket capacity of 0.66 to 1.57 cubic yards. The machine’s hybrid system works on the principle of swing energy regeneration and energy storage through the use of an electric swing motor. The kinetic energy generated during the swing braking phase is converted to electricity, which is sent through an inverter and captured by the capacitor. The captured energy is then discharged quickly for upper structure rotation and to assist the engine when accelerating under work load conditions. Tests comparing the hybrid to Komatsu’s standard excavator showed a 25- to 40-percent reduction in fuel consumption, according to the company.
Portable, easy to operate equipment line
KPI-JCI says the high crushing capacity of its new GT200 cone crusher plant, one of the company’s new affordable line of Global Track Series equipment, creates more saleable materials per pass, saving time and increasing profitability. The crusher’s dual-motor design allows for quick closed-side setting adjustments to ensure precision while crushing.
High-production, fuel-efficient wheel loaders
Volvo says its new L220F wheel loader is the toughest of its F-Series line, featuring a breakout force of 50,470 pounds and a bucket capacity of 7.1 cubic yards. The Tier 3-certified V-ACT engine provides high torque at lower speeds, allowing the engine to operate with low levels of noise and exhaust emissions. Other features include the new OptiShift, with patented Reverse by Braking; a patented T-linkage, lift-arm system; and an ergonomically designed machine operator’s cab (Care Cab) with improved sound and vibration dampening. All F-series wheel loaders are 95-percent recyclable.
Self-service ticket kiosk and print terminal
Libra Systems’ self-service kiosk allows for more truck traffic at the scale without increasing costs. The kiosk frees up scale house operators, reduces data entry and ticket errors, reduces in-yard times, quickly and automatically identifies trucks, and controls truck flow.
TCI Manufacturing’s new floating transfer conveyors are designed to work with the company’s bucket dredge to transport materials across water. The conveyors are built with a swivel point for dredge movement and feature a radial-type receiving hopper. Features include a head-end turn style, head-end discharge hood, and a catwalk and handrails around the head end and down the drive side of the conveyor.
Harp wire reduces downtime
Major Wire says its new LFM Harp Wire is manufactured with straight wires firmly molded into polyurethane strips that hold the wires in place at the crown bar, eliminating steel-on-steel wear. The polyurethane strips are said to keep the wires equally tensioned, creating better wire vibration, reducing blinding, and increasing production of a cleaner aggregate. The company says its new wire handles high-impact loads better and lasts up to twice as long as conventional harp and piano wire.
Earthmover tires for rocky terrain
Michelin Earthmover Tires says its new X-Traction tires are now available in North America. The E4 tires are designed for earthmover transport equipment operating in rocky terrain. A new cooling system shoulder design and C2 Technology casing architecture reduce heat build up, allowing trucks to operate continuously at higher speeds. The tires feature 13-percent deeper tread and thicker under-tread rubber for resistance to cuts and impacts.

A 55- by 32-foot unrestricted feed opening prevents bridging and maintains consistent feed. Features include a hydraulically adjustable product conveyor with a 13-foot, 1-inch discharge height; a modular hopper that can be removed for transport; and two-speed tracks for maximum site mobility. The product conveyor can be raised and lowered hydraulically during operation and for transport or maintenance.
Weigh on the go
Rice Lake Weighing Systems’ new WLS-C compact on-board weighing system for skid steers, wheel loaders, track loaders, and lift trucks offers a compact profile that fits easily into any cab, at an economical price. The system installs with a printer to create an all-in-one mobile weighing and ticketing operation, thereby reducing unnecessary trips to a central scale.
Land-based bucket-ladder dredge
Rohr Corp.’s newest development in underwater mining technology, its land-based, bucket-ladder dredge, is new in the United States. The company says the dredge can extract deposits at shallow-water depths of 36 to 40 feet. Once extracted, the material can be stockpiled, conveyed directly from the dredge, or fed onto a haul truck.
40-ton articulated truck enters the market
Terex says its new 40-ton TA400 articulated truck features a Tier 3-compliant, fuel-efficient, 450-horsepower diesel engine; maximum rim-pull and gradeability for negotiating inclines; and a large body capacity with low body weight to maximize load size and retention.
