The new Cat® C Series articulated dump trucks—725C, 730C, and 730C EJ ejector—feature new engines with more power, advanced transmission control, enhanced operator amenities, new serviceability features, and for the 730C and 730C EJ models, automatic traction control. The 725C has a rated payload capacity of 26 tons and the 730C and 730C EJ models are rated at 31 tons. The Cat C9.3 ACERT engine powers the 725C and is rated at 314 net horsepower, and the Cat C13 in the larger models has 367 net horsepower.
The Cat MH3037 is the third model in a new wheeled-material-handler range that Caterpillar is introducing in the greater-than-25-ton size class. The MH3037 is purpose-built, says Caterpillar, to work productively and durably in industrial, scrap recycling, mill-yard and waterway applications. A patented “ground entry and exit” system features a step-in cab that lowers to the front or the side of the machine, facilitating convenience and safety for operators and service personnel, says the company.
Two new Cat compact wheel loaders—the 910K, a new model in the range, and 914K, replacing both 914G2 and IT14G2¬—feature Caterpillar's Optimized Z-bar loader linkage, allowing these new models, says the company, to work with the digging power of conventional Z-bar machines, while also providing the parallel lift of an integrated tool carrier. Both models use a 92-net horsepower, Tier 4 Interim engine, the Cat Hystat hydrostatic drive system, and newly designed cabs. High-lift booms, couplers and a range of work tools, including Cat Performance Series buckets, are available.
The new Cat M Series 3 motor graders—12M3, 140M3, 160M3 and their all-wheel-drive (AWD) counterparts—meet Tier 4 Final emissions standards and incorporate a number of new features designed to enhance operating efficiency. For Tier 4-Final, Caterpillar has added a selective catalytic reduction (SCR) system to the after-treatment strategy used on the M Series models. A new, operator-selecetd Economy (ECO) Mode is designed to save fuel by reducing engine speed, allowing the machine to work in a more efficient range.
Caterpillar’s new range of utility compactors, (CB22B, CB24B, CB24B XT, CB32B, CB34B, CB34B XW, CC24B and CC34B) compete in the 1.8-metric ton to 5-metric ton size class and, according to Caterpillar, feature a simple operating environment with intuitive controls and easy-viewing LCD display. Efficient compaction performance is achieved, says the company, via better visibility, increased drum diameters, multiple- frequency vibratory systems, and optional ballast addition on some models.
According to Caterpillar, Cat Connect, a new framework for construction technologies and services, helps customers monitor, manage and enhance operations to gain more control of jobsites. Using data from technology-equipped machines, says Cayterpillar, customers get more information and insight into equipment and performance than ever before.
The new Cat 336F hydraulic excavator meets Tier 4-Final emissions standards and delivers fuel-saving performance, says Caterpillar, via its electric boom- and stick-regeneration valves and an engine idle shutdown setting that stops the engine after a specified interval of idling. In addition, the operator can reduce engine speed to idle with the touch of a button, and an economy power mode further reduces fuel consumption.
The new Cat 620 K Series Wheel Tractor-Scrapers—621K, 623K, and 627K—refine the design of their H Series predecessors, which introduced features such as Sequence Assist and Load Assist that automate cycles. K Series models build on the design of their H Series predecessors with new features, including high pressure steering, engine over-speed protection, tire spin reduction, differential lock engagement protection, machine/ground-speed control, and a payload-estimator system.
A new Cat Pin Grabber Coupler for excavators is designed to meet or exceed global industry standards for coupler safety, including the European Union EN474 standard and the ISO/DIS-13031 "best practices" ruling. The coupler’s design has earned several patents, and more are pending. The new coupler will be the only coupler available for factory and retrofit installations and can be used for all Cat D, E and F Series excavators, models 311 through 390. The new coupler works with Cat buckets and most competitive buckets.
According to Caterpillar, the new Cat® 323F L ES (Extreme Service) hydraulic excavator is a specially designed machine with reinforced structures and massive counterweight to take on the most severe applications. The machine delivers 20 percent more over-the-side lift capacity than its conventional 20-ton counterpart and has the stability, says Caterpillar, to handle the largest of work tools, such as thumbs and grapples.
Caterpillar has expanded its heavy-duty line of Class 8 work trucks with the new Cat CT681 vocational truck, a set-forward-axle model designed for customers who prefer a longer wheelbase truck or who must comply with restrictive load limitations on bridges and roads. The CT681 joins the company’s CT660, which has a set-back front axle. Unveiled at CONEXPO-CON/AGG 2014, the CT681, says Caterpillar, has been working in a variety of field-testing applications since the third quarter of 2013.
According to JLG, its new1850SJ Ultra Series boom lift delivers 19 stories of working height, allowing access to applications previously reserved for truck-mounted booms. The new model has a platform height of 185 feet, a reach of 80 feet, and a maximum capacity of 1,000 pounds. The boom extends from ground to full height in less than five minutes, the company says. A telescopic jib extends and retracts to provide additional reach, as well as to provide up-and-over capability and the ability to telescope into and around structures in various applications.
The NP15 crusher has been added to the Nordberg NP Series from Metso Mining and Construction. The steep feed angle increases material penetration into the rotor. It accepts feed material up to 400mm and maximum throughput capacity is up to 12 percent bigger than its NP1315 siblings. Fewer side liners means more flexibility in the use of the side liners and less parts in stock, compared to the NP1315. A two-part rear frame allows the operator to choose which way to open the frame depending on the point that needs to be accessed.
Mobile Twin Shaft (MTS) concrete plant mixer has a low mixer charging elevation and 12 foot 8 inch-minimum discharge height for use with most locations and fleets without having to lower the grade elevation, the company says. The 42-inch wide conveyor belt design allows for fast truck charging and minimal spillage. The plant’s electrical panel is manufactured in-house and is UL-listed, which the company says eliminates field certification requirements. The wash system provides high pressure cleaning for the mixer, conveyor, and transporter.
The P185 and C185 compressors are now powered by a Tier 4-Final, 49-horsepower Deutz D2.9 L4 electronic engine. At 100 percent load, the P185 and C185 run nine and seven hours, respectively, and provide 100 psi at 185 cubic feet per minute.
Guntert & Zimmerman’s EGON IntelliMatics expands monitoring engine functions to catch small issues in all aspects of machine operation including hydraulic and electrical functions. The S600 Multi-Purpose Slipform Paver will be equipped with this feature.
The DX225LC-3 excavator is powered by a 167-horsepower DL06K engine that is Tier 4-Interim compliant using CEGR. The excavator weighs 49,604 pounds, has a bucket breakout force of 33,510 pounds, arm breakout force of 23,810 pounds, digging reach of 31 feet 10 inches, and dump height of 22 feet 5 inches.
The SLV90-2 compact track loader has a Tier 4-compliant, 92-horsepower, four-cylinder engine. The track loader has a breakout force of 7,961 pounds and a lifting capacity of 5,869 pounds. Bucket options include teeth, straight-edge, four-in-one, pallet forks, and others.
The company’s largest cold mill, the W 250i, has a maximum power rating of 991 horsepower and wide conveyor slewing angles to make the milling process more efficient. It has a milling depth of up to 13.8 inches.
Genie BE69 series rough-terrain, electric scissor lifts are bi-energy (BE), or hybrid, units. The 69-inch lifts include GS-2669, GS-3369 and GS-4069 BE models, corresponding to heights of 26, 33 and 40 feet. A 5-foot slide-out deck provides users with room to work; lift capacity is 1,500 pounds.
