New Compact Excavator

June 26, 2017

Komatsu’s new Tier 4 Final PC138USLC-11 features excellent lift capacity, stability and performance in a compact model designed to fit a variety of applications. If the tracks can fit through an area, then there is enough space so that operators can swing without worrying about hitting an obstruction.

Upgrades, updates and enhancements. Each new model that Komatsu produces has them, and the PC138USLC-11 Tier 4 Final excavator is no exception, with productive features that provide excellent lift capacity, stability and performance in a compact model design that fits a variety of applications.

“The PC138USLC-11 is the perfect machine for contractors on highway, bridge and other roadwork jobs,” said Kurt Moncini, Komatsu Senior Product Manager. “It’s easy to transport, versatile and the tight tail swing fits easily within one lane of traffic. Even though it’s compact, the excavator has a robust counterweight and can be an effective tool on large, open jobsites, too.”

The 7,630-pound (3460 Kilograms) counterweight provides excellent lift capacity, equal to or better than conventional models in the same size class. The contoured cab profile and sliding door allow the cab to swing within the same radius as the counterweight.

“If the tracks can fit through an area, then there is enough space for operators to swing without worrying about hitting an obstruction,” said Moncini. “That gives them confidence to work in congested areas, close to power poles or transformers and up against, or even inside of a building.”

Like other Tier 4 Komatsu machines, the PC138USLC-11 features Komatsu hydraulic technology that matches engine speed and hydraulic pump output for optimal performance. Operators can also match the machine to the materials and the job at hand with six working modes, including Power, Economy and Attachments. An enhanced attachment control stores up to 10 attachments in the monitor panel, with adjustable flow control. Two-way attachments also run in Economy mode for greater efficiency.

Improved telematics

Komatsu upgraded its telematics technology to cellular, ensuring that when work is performed inside a building, KOMTRAX information remains available. Operators can view it through an updated monitor panel that also incorporates a standard, rearview-camera output that’s always available on the screen.

“Ground-level access to service points are all located on one side, including fuel, engine oil and air filters,” said Moncini. “That saves time, which can be better spent in production. It’s a terrific all-around machine that’s built for great production, even in less-than-ideal conditions. The PC138USLC-11 would be a valuable addition to any fleet.”
