Bobcat enters compact tractor market
Bobcat’s three-model lineup of compact tractors, the CT120, CT225 and CT230, are the first of what will eventually be a nine-model offering. The CT230 (pictured) has a 30-horsepower engine with three travel speed options. Difficult terrain is handled through four-wheel drive and a hydrostatic transmission. Weighing 3,055 pounds, the CT230 is 56 inches wide with agricultural tires, 118 inches long and 96 inches high with the ROPS deployed. The ROPS can be folded down for transport or storage. Available attachments include an angle blade, box blade, finish mower, post-hole digger, seeder and tine rake, as well as a front-end loader and attachments.

Electronic loader control, one-touch idle offered on Case M Series 3 backhoes
Case Construction Equipment’s M Series 3 backhoe lineup includes the 580M, 580 Super M, 580 Super M+, 590 Super M and 590 Super M+. The five models range in net horsepower from 79 to 109 with dig depths from 14 feet 3 inches on the standard backhoe to 20 feet 4 inches with the Case Extendahoe. The loader end on the series has an electronic auxiliary control, which allows precise, easy control of attachments such as the 4-in-1 bucket. The backhoes are now available with a one-touch idle built into the machine’s pilot controls, which allow you to return the engine to idle at the touch of the button instead of using the rotary hand throttle. Pressing the button a second time returns the engine up to the previous rpm setting.

Structural rigidity extends paving widths
Built for highway, industrial and airport paving, the Terex SF3500B Series concrete slipform pavers have a 26-inch main frame tubing to offer improved structural rigidity at extended paving widths. With the capability of telescoping up to 8 feet from one side of the paver, the machine can deliver nearly zero deflection paving, according to the company. The vibration manifold is mounted directly to the paving kit, reducing the total vibrator hose length by nearly 500 feet at a standard 24-foot paving width. This also helps improve visibility, reduces heat and lessens tear-down time. The manifold’s 3,000-psi, high-pressure spinner fittings offer leak-free disconnects.

Sany truck-mounted pump vertical height reaches 215-plus feet
Sany Heavy Industry’s 66m truck-mounted concrete pump boasts a vertical height of 215-plus feet, which the company says gives it the longest arm support in the world. A heavy-duty delivery cylinder prolongs the service life of wear parts. The concrete pump has an output of 261 cubic feet per hour and arm support damping technology that reduces 50 percent of jitter at the end of the hose, says Sany. The forward-swing, multi-stage extendible support leg enables unilateral support and quick expansion, and allows the machine to adapt to narrow spaces.
