The SK520LC-11 features an operating weight at approximately 121,000 pounds. It delivers a dynamic bucket digging force of 72,200 pounds and achieves a lifting capacity of 46,540 pounds while minimizing fuel consumption. The SK520 is powered by a 463-horsepower Tier IV Final Isuzu 6WG1 engine.

“Independent Travel,” an exclusive KOBELCO feature, enables the SK520 to move, lift, and swing simultaneously without experiencing loss of power.

An optional counterweight removal system further enhances the SK520’s performance and operation to make this machine easier to move from one job site to the next. This feature makes counterweight removal and installation a quick, simple process to reduce costs and increase safety. Operators can choose from multiple working modes to optimize performance for specific tasks.

Built to withstand the toughest working conditions, the SK520LC-11 features materials and components that ensure long-lasting durability. Convenient access to all service points allows quick and efficient day-to-day maintenance.

The SK520LC-11 carries as standard a four-year or 4,000-hour warranty, with optional extended warranty options possible with the KOBELCO Premium Protection Plan.

The spacious cab offers visibility and ergonomics, reducing operator fatigue during long hours of operation. User-friendly controls and advanced monitoring systems ensure safety and efficiency.

Standard features include a heated air ride, seven-way adjustable suspension seat; multi-vent air conditioner; radio with USB, AUX, and Bluetooth capabilities; ergonomic, adjustable pilot control levers; and rearview and right-side cameras.

The SK520LC-11 is equipped with a range of technological advancements designed to boost efficiency and reduce environmental impact. Energy-saving modes and automatic idle shutdown contribute to lower fuel consumption and reduced emissions, aligning with KOBELCO's commitment to sustainability. The excavator’s 10-inch color monitor allows the operator to select the most important information needed to ensure safety and machine control.

The new model can be equipped with a variety of attachments, including different types of buckets, hammers, and grapples. The auxiliary flow rates are all adjustable by the operator through the in-cab monitor. Mode settings for other attachments like a tilt-rotator can also be added or changed.
