Kobelco Construction Machinery USA has introduced its Tier IV Final SK350LC-9E model to the North American market. Kobelco’s SK350 is among the company’s largest crawler excavator models and is well-equipped to provide operators with enhanced power and efficiency, while meeting the latest Tier IV Final emissions standards. The SK350 is set to deliver significant operational cost savings due to better fuel economy, greater efficiency and reduced service intervals, according to the manufacturer.
Kobelco’s 82,200 lb. (37,285 kg) SK350 is powered by a 270 hp, Tier IV Final HINO engine allowing the machine to tackle a wide-range of heavy-duty applications with ease, while remaining highly fuel efficient. This model incorporates both selective catalytic reduction (SCR) and self-cleaning diesel particulate filter (DPF) systems to provide the lowest possible operation costs. This dual system minimizes diesel exhaust fluid (DEF) consumption when compared to SCR only systems. Kobelco’s Tier IV Final solution delivers as much as a 10 percent reduction in fuel consumption as compared to a Tier III machine, a tremendous benefit which Kobelco achieved by studying and refining its hydraulic system performance in real jobsite conditions.
Efficiency on the SK350 came as a result of an extensive evaluation of the hydraulic and control systems with a focus on reducing parasitic losses, while maintaining peak productivity. Hydraulic system improvements as a result of this evaluation include reduction of power loss due to hydraulic restrictions, fine matching of pump performance to actual job conditions and the ability to operate at maximum efficiency when heavy-duty work is not required, according to the manufacturer.
In addition to power and fuel economy, the SK350 boasts increased digging capabilities. With a digging force of 50,600 lbs., a digging depth of 24 ft. 10 in. (7.5 m), a suggested 0.875 to 2.75 cu. yd. (.6 to 2 cu m) bucket range and a swing speed of 10.0 rpm, this crawler excavator ensures quick cycle times to keep productivity levels on point regardless of the application.
Kobelco’s SK350 showcases the company’s proprietary intelligent control system, ensuring smooth engagement and disengagement across all machine functions. Heavy lift mode can be enabled when extra lift capacity is needed, while power boost gives operators 10 percent more power for additional digging capability with no time limit. The SK350 also comes standard with Kobelco’s independent travel feature. This function allows the excavator to travel and lift simultaneously without experiencing a loss of power or speed, making it both versatile and safe to operate across a wide variety of applications. In many instances, this Kobelco exclusive feature eliminates the need of contractors to supplement their fleet with other types of carriers.
The SK350 is ergonomically designed with a spacious, climate-controlled cab with plenty of leg room and operating space. Wide access doors provide ease of entry and exit, while windows on all sides offer excellent visibility, ensuring safe operation, particularly in the rear, due to Kobleco’s low profile hood design. A rear view camera with an LCD monitor is installed as standard equipment for additional safety. A 7-way adjustable suspension seat, AM/FM radio, large cup holder and ample storage tray for personal belongings give operators a pleasant work environment on even the toughest of work days. Additionally, operators can look forward to ease of use in the SK350 with centralized controls, easy-to-read instrumentation and onboard self-diagnostics, including warning screens and audible alarms, which alert the operator to the status of critical equipment functions.
Kobelco’s SK350 is not only comfortable to operate, but it’s also built-to-last. This rugged excavator is built with forged and cast steel materials for maximum durability and features reinforced high stress areas on the arm and boom, wide welds and a standard rock guard. Its sturdy undercarriage with heavy-duty track guides and rollers, as well as a thick base plate and grousers, make the SK350 ideal for the most challenging of job sites. Self-lubricating bushings at the attachment pins and abrasion resistant bushings near the bucket come standard.
The SK350 is equipped with Kobelco’s KOMEX machine operation management system, which allows owners access to crucial machine data including location, operating hours, fuel consumption and maintenance status. Operators and fleet managers along with Kobelco dealers and service personnel can easily view all vital equipment information to more effectively plan jobs and schedule regular service intervals.
Maintenance is easy on the SK350, and now even more cost effective. Operators can expect extended service intervals by as much as 100 percent or more when it comes to engine oil, hydraulic oil, filter changes and greasing. When periodic maintenance is required, the SK350 can be worked on at ground level with easy access to all key service points.
