INNOVATIONS EQUIPMENT & PRODUCTS BOBCAT UPGRADES LOADER SERIES Building on the productivity of the Bobcat 700 and 800 frame-size loaders, significant upgrades have been made to the skid-steer loaders, compact track loaders and all-wheel steer loader. Upgraded loader features apply key interim Tier 4 (iT4) technologies to pro- vide enhanced loader functionality and re- porting for machines with horsepower ranging from 75 to 174. Machines in this horsepower class include Bobcat's 700 and 800 frame-size loaders, consisting of seven M-Series loaders: the S750, S770, and S850 skid-steer loaders; the A770 all-wheel steer loader; and the T750, T770 and T870 compact track loaders. Other upgraded features include: Increased breakout and lift forces. Bob- cat 800 frame-size loaders (S850 and T870) have been equipped with increased hydraulic pressures and industry-leading breakout and lift forces, resulting in shortened digging cy- cles, notes Bobcat. The iT4-equipped T870 will have nearly 17 percent more lift break- out force than the Tier 3 model. Less noise, better fuel consumption. For Bobcat loaders equipped with Selec- table Joystick Controls, an optional auto- idle function is available. The feature automatically activates, causing the en- gine rpm to drop to idle if a loader's func- tions are not used within five seconds. Horsepower management updates. The new iT4 engines can interpret information that will allow horsepower management— a standard feature of Bobcat Selectable Joystick Controls—to be based on engine torque instead of engine rpm. This mini- mizes engine stalling and provides addi- tional travel speed at low-mid engine rpm. New M-Series loader hydraulic control valve. A new hydraulic control valve allows use of the tilt function—rolling out or rolling back an attachment—regardless of auxiliary system pressure. M-Series instrument panel updates. All deluxe instrument panels in M-Series loaders, including 600 frame-size loaders not affected by iT4 in 2012, will provide simplified navigation and more in-depth information regarding operator and ma- chine performance. Machine performance displays. The 5- in., full-color LCD screen now offers a display screen titled "Machine Performance," which provides three functions—viewed only by owner-level individuals—to assist with mon- itoring key data to determine productivity rates by operators and other project metrics. Those functions include user login informa- tion, overall job statistics and user job sta- tistics. New screens viewed by all users include vital information such as real-time fuel consumption and emissions data. Ultra-low-sulfur diesel fuel (15 parts per million). As with all iT4 emissions con- trols technologies, only ultra-low-sulfur diesel (ULSD) fuel may be used in iT4 com- pliant 700 and 800 frame-size loaders. HOLLOW HOLE HYDRAULIC CYLINDER To meet the needs of big jobs such as crane assem- bly, rigging and heavy construction demanding re- liable portable power. The company has introduced a 1,000 ton capacity, double-acting hollow hole hy- draulic cylinder. This cylinder joins the other rugged hollow hole cylinders in the Trompler line of off-the-shelf hydraulics. These cylinders have a maximum pressure at 10,000 psi, and their piston design enables pow- ered push/pull forces. Made in the USA, the Trompler hollow hole cylinders have an en- hanced design for reliability. A number of quality features including industrial hard chrome pistons, high strength heat-treated steel and heavy-duty bearings enable Trompler to back up these cylinders with a life-time warranty covering workman- ship and material defects. — www.tromplerflu- idpower.com 48 | SEPTEMBER 2012 WWW.CONCRETEPRODUCTS.COM
