Kobelco Construction Machinery USA introduced a 55-ton excavator for mining and construction applications. The new SK520LC-11, which is part of Kobelco’s -11 series, has an operating weight of about 121,000 pounds, offering what the company describes as top-performing cycle times, lift capacity and digging force. The excavator delivers a bucket digging force of 72,200 pounds and features a lifting capacity of 46,540 pounds. A 463-hp Tier 4 Final Isuzu 6WG1 engine powers the excavator. Independent travel, a Kobelco feature, enables the SK520 to move, lift and swing simultaneously without experiencing loss of power.
Motorized torque-arm enhancements elevate gear reducer performance
Dodge Industrial unveiled advancements in its motorized torque-arm (MTA) lineup. According to Dodge, its MTAs are the only AGMA-rated direct-drive reducers. Now, the company’s MTA lineup is larger and offers new capabilities. Larger 9, 10 and 12 reducers, for example, now support up to 329,000 inch-pounds of torque. Additionally, assembly packages with reducers sized 7 to 12 and Atlas Adapter support large foot-mount motors 60 hp and above, reducing the need for spare motor inventory by allowing the use of standard foot-mount motors in sizes not commonly stocked in C-face styles. Dodge says C-face safety input adapters enable access to the coupling through a split cover to eliminate the need to remove the motor.
