With a digging force of 24,800 pounds, the SK140SRLC-7 has a compact design and long digging reach capabilities.  The unit has 19-foot 7-inch dig depth and an 11-rpm swing speed, which shortens cycle times by around 10 percent, says the company.

A 105.4-horsepower Isuzu engine increases the machine’s power output over its predecessor by around 10 percent. The SK140SRLC-7’s 31,700-foot-pound  drawbar pulling force gives the machine “powerful travel capabilities, enabling it to tackle steep and rough terrain with ease,” says the company. And independent travel allows the machine to move, lift and swing simultaneously without experiencing loss of power.

An attachment selection system with adjustable flow-rate presets for the bucket, breaker, nibbler and thumb allows the operator to quickly change between tools. The model is also available with an optional offset boom, designed to increase stability and maneuverability while working in confined areas, such as next to walls or close to traffic.

The machine comes standard with an ergonomic lever and Grammer air ride suspension seat to reduce operating force and fatigue. The SK140SRLC-7’s cab features  include an optimized control layout with a new jog dial and 10-inch color monitor. An unfastened seatbelt indicator and built-in rear, left and right-side cameras with a customizable split-screen display function enhance operator awareness and jobsite safety, says the company.

Remote diagnostic and preventive maintenance systems on the machine allow easy access to maintenance data from the operation management system. Operators can expect extended service intervals when it comes to engine oil, hydraulic oil, filter changes and greasing, according to Kobelco.
