KOBELCO SK45SRX-7 Mini Excavator

Feb. 16, 2022

Model SK45SRX-7 KOBELCO excavator is a mini excavator with an operating weight of 10,300 pounds with cab. It has a 37-horsepower Yanmar diesel engine.

Max digging height with the standard arm is 18 feet 10 inches, max reach at ground level is 18 feet 8 inches, and max dig depth is 11 feet 3 inches.

A new hydraulic system on the KOBELCO mini excavator shortens the digging cycle by up to 7 percent compared to the previous 6E series, without reducing speed. Redesigned travel motors increase the travel speed by up to 5 percent. Other benefits of the new hydraulic system include smoother operation and improved levelling performance. The Integrated Flow Pump System enables operators to harness extra output from the third pump, which otherwise powers the swing and dozer circuit. This additional output is directed to the arm and boom for added power when digging, resulting in a fast and smooth raising operation, even with heavy loads.

The KOBELCO SK45SRX-7 is a compact tail swing mini excavator with a standard arm of 5 feet 1 inch. It has a preinstalled thumb bracket.

A 2-way dozer blade with float comes standard, and the blade is designed so earth falls forward and not behind the blade when dozing.

Inside the cabin, the dozer can be controlled by the ergonomically designed lever, which is easier to grip, and the first and second speed switches have been repositioned to improve maneuverability.

The boom, arm, and swing bracket all have large cross-section segments for added attachment strength, and the bolt-tightened pins firmly lock the boom to prevent the boom top from opening laterally. The bucket features a cast-iron idler link, and the box construction dozer supports provide greater strength.

The mini excavator line comes with a standard 3-year or 3,000-hour warranty.
