    cex0805conexpo4
    The new F-Series engines from Fiat Powertrain Technologies (FPT) — using an inline, four-cylinder design and having a displacement of 3.2 liters — are designed specifically for off-road and stationary applications. Meeting Tier-3 emissions standards and available in horsepower ratings of 74, 82 and 87 (at 2,500 rpm), the F-Series models feature two valves per cylinder, cast-iron cylinder head, mechanical fuel-injection, and structural or non-structural architecture. The new engines also may be configured with either an internal or an external EGR (exhaust-gas-recirculation) system and, further, as either turbocharged or turbocharged-and-aftercooled.

    Caterpillar D7E Electric-Drive Dozer

    cex0805conexpo1

    Caterpillar claims its 59,000-pound D7E track-type tractor's electric drive system will deliver 25 percent more material moved per gallon of fuel than the D7R Series II dozer. A 235-horsepower Cat C9 diesel drives a generator to produce electricity that ultimately powers two AC electric drive motors, which are connected to a differential steering system, final drives, and a low-sprocket undercarriage. The electric drive train has 60 percent fewer moving parts compared to previous D7s. The drive eliminates gears to shift and is said to perform much like a hydrostatic drive, albeit with faster response to load demands. It is expected to be available in 2009. See video, specs and more!

    cex0805conexpo2
    The first compact track loader IHI/CES has manufactured is the CL35, with a rated operating capacity (50 percent of tipping load) of 2,310 pounds. The 7,826-pound CL35 is powered by a 67-horsepower Yanmar diesel. With a radial lift path, the loader arm generates 5,710 pounds of breakout force and 6,474 pounds of bucket breakout force.

    JLG FS80LiftPod

    cex0805conexpo5

    According to JLG, its new FS80 LiftPod is "the most portable aerial work platform in the world." Each of the LiftPod's five modules (base, mast and carriage, platform, power pack and work tray) is designed to be "carried by one person and can be assembled in around 30 seconds." The LiftPod is a practical alternative to a ladder and typically can be transported in the back of a utility vehicle. The 63-pound base of the LiftPod is made of high-strength steel and its mast (44 pounds) and platform (30 pounds) of lightweight aluminum. The unit's power pack (15 pounds) can elevate and descend with a worker an average of 20 times before recharging is required. The LiftPod has a platform height of 7 feet 8 inches, a platform size of 24×20 inches, and a platform capacity of 300 pounds.

    Miller Electric PRO 300

    cex0805conexpo6
    The PRO 300 diesel welding generator has been improved by using fewer and more robust electronic components. An optional 4-cylinder, 24-horsepower Deutz engine provides more power for using larger electrodes and gouging with carbons up to 1/4-inch diameter, the company says. More power also compensates for less oxygen when working in higher elevations. The unit offers better E6010 performance for downhill pipe welding, as well as better MIG, flux cored and TIG arc starts. It provides 20 to 410 amps of welding power, as well as 12,000 watts of peak generator power.

    Bobcat Suspended Undercarriage

    cex0805conexpo7
    Responding to customer requests for a smoother ride fromcompact track loaders, Bobcat developed a roller suspension system, which is currently available as an option for the T320 compact track loader and will become available for more of the company's rubber-track models later this year. In the new suspension system, the rollers are suspended by high-strength-steel leaf springs as a means of reducing vibration. In addition, the system used track idlers that have been raised to make the machine easier to turn. A further advance built into the new suspension system is provision for a larger area around the sprocket to facilitate cleaning. Video coverage

    JCB 409 Wheel Loader

Using a standard 1.3-cubic-yard bucket, the 409 has a straight tipping load of 10,480 pounds, and a full-turn tipping load of 8,628 pounds. (When equipped with pallet forks, says JCB, the 409 can handle a 5,500-pound load.)

    ESCO Ultralok Bucket Teeth

    cex0805conexpo27
    ESCO's new Ultralok Tooth System eliminates a separate pin from the tooth/adapter interface. Each tooth/point has an integral hammerless locking mechanism to simplify installation and replacement. The Ultralok retainer is integrated into the tooth, so there is no separate pin to manage during installation and removal. It will be offered in seven construction sizes. The tooth-and-adapter line will supply 6- to 75-metric-ton excavators and 3- to 12-cubic-yard wheel loaders. Key to the Ultralok system is that the adapter carries the load, and the pin simply retains the tooth on the adapter during most of the duty cycle. Video coverage.

    John Deere Diesel Engines

    cex0805conexpo56
    To achieve compliance with Interim Tier 4 off-highway emissions required in 2011 for engines 174 horsepower and up, John Deere Power Systems will not use selective catalytic reduction, but rather will add a diesel oxidation catalyst/diesel particulate filter unit to its Tier-3 PowerTech engine to achieve the 90-percent diesel particulate reduction required. Selective cata-lytic reduction requires the vehicle be fitted with a separate tank, a urea injection system, and a legislatively required tamper-proof diagnostic system. For the required 50-percent reduction in oxides of nitrogen, Deere will increase the percentage of cooled exhaust gas recirculation.

The 764 HSD weighs in at 32,000 pounds and is powered by a 200 horsepower Deere PowerTech 6.8-liter engine. Video, specs and more

    Astec Double Barrel Green System

    Astec says its Double Barrel Green System reduces the mixing and
    compaction temperatures of asphalt without sacrificing the quality of the pavement. The new system is considered a warm mix process. However, unlike other warm mix technologies, the process does not require the addition of expensive commercial additives, Astec says. Instead, water is injected into the mix along with the liquid asphalt cement. Water causes the liquid asphalt to foam and expand in volume, yielding a temperature that is about 50 F less than traditional hot mix asphalt.

    Doosan DL Wheel Loaders

    cex0805conexpo44

    Doosan has added four new wheel loaders to its DL series: DL200TC, DL250TC, DL300 and DL450. Bucket capacities range from 2.6 cubic yards to 6.3.

Four-fold, full-floating and height-adjustment system ensures that the machine aligns parallel to the pavement during milling and transport.

    Topcon Fast Grading System

    cex0805conexpo49
    Topcon's newest machine-control system, 3D-MC2, is claimed to increase the travel speed of dozers by more than 200 percent while maintaining grading smoothness. With new sensor technology — a combination of inertial sensors and gyros — the calculation of positioning is sped up by a factor of 10. This reduces the inherent latency of traditional GPS technology and allows for faster, accurate positioning in real time. According to Topcon, 3D-MC2 breaks down the "last barrier" of grading productivity — speed — and will change the role of the dozer on the jobsite.

    MOBA Grade Control

    cex0805conexpo52

    Backwards-compatible to prior MOBA products, the GS-506 grade-control system for graders and dozers likewise uses five sensors to control the blade. In this case, rotation, long-slope, and cross-slope measurements are combined with the new MOBA SonicSki+ ultrasonic sensor and/or the new LS-3000 laser receiver. The SonicSki+ utilizes extended side-shift functions, has a working range up to 4 feet, and can be used over a string line or curb edge due to the use of six transducers. The LS-3000 receiver offers a full 360-degree detection range for grading of large areas. For the machine operator, an integrated shield combined with manual contrast control allows for clear reading in all light conditions.
