Sany America, Peachtree City, Ga., will introduce two new rough-terrain cranes, SRC860XL and SRC840, and display its first self-assembling crawler crane, SCC8300, at ConExpo-Con/Agg 2011. The SRC860XL has the longest main boom in the 60-ton capacity class. The five-section main boom has a 140-foot maximum length. The boom can also be equipped with a 53-foot bi-fold jib. The crane was designed specifically for the transportation requirements of the U.S. market.
A fully optioned machine weighs 98,000 pounds. Measuring 10’x10’, the crane to be moved for minimum cost. Its powertrain features a 250 hp Tier-3 Cummins engine coupled to Dana Powershift transmission (six-speed forward and reverse) and Axletech axles. The standard tires are Bridgestone radials (29.5R25).
Rated at 40 tons, the SRC840 will be the industry's strongest crane in the 30- to 40-ton market. The four-section main boom extends to 110 feet. The addition of a 45-foot bi-fold jib increases maximum tip height to 154 feet. For simplicity and commonality of design, the SRC840 also uses the same manufacturers for its powertrain features.
All Sany rough-terrain cranes come with a Sany-designed LMI system including a large display screen. The LMI has two display modes, one for crane operations and one for traveling. Using the large touch screen the operator can easily switch between display modes as well as function its setup.
In addition, the company’s first self-assembling crawler, the 330-ton SCC8300, is designed to meet the transportability needs of global customers, especially those in North America. The new family of cranes, which is being developed under the direction of veteran crane designer John Lanning, will be tested to ANSI B30.5 standards with independent third-party verification. It will feature two full-power load hoist drums mounted in the butt of its 203-foot boom. The crane has a 59-foot fixed jib and features Sany’s LMI system. A Cummins QSM11 Tier-3 engine delivers 400 hp at 1,800 rpm and full open-loop hydraulic power transmission has electrical controls.
