Komatsu introduces new hydraulic excavator

The excavator features six working modes, with energy saving guidance incorporated into the cab’s monitor panel.

Komatsu America Corp’s new PC238USLC-11 hydraulic excavator boasts a four per cent productivity increase as well as a decrease in engine parasitic loads, when compared to its predecessor.

The new machine is built with a heavy counterweight mass and rounded cab for true tight tail swing performance and improved lift capacity. The hydraulic excavator also features six working modes, with energy saving guidance incorporated into the cab’s monitor panel.

“The PC238USLC-11 maintains the tight tail swing radius of its predecessor, making it well suited for utility and highway applications working in confined spaces,” said Andrew Earing, product manager of tracked machines for Komatsu America.

“The machine’s contoured cab profile and sliding door allows the cab to swing within the same radius as the counterweight. The additional counterweight remains standard, giving the PC238USLC-11 equal or better lift capacity than conventional models in the same size class.”

The hydraulic excavator is equipped with an EPA Tier 4 Final certified, 6.69 litre engine with 167 hp. The machine uses a Komatsu Diesel Particulate Filter (KDPF) and selective catalyst reduction system, with Diesel Exhaust Fluid (DEF) injection used to meet the Tier 4 Final requirements.

Komatsu also added exhaust gas recirculation to reduce nitrogen oxide emissions.

As well, parasitic load on the engine is reduced via a new temperature controlled viscous fan clutch. Auto idle engine shut down helps reduce non-productive engine idle time and reduces operating cost.

The new hydraulic excavator is available with Komatsu’s new KomVision system, a birds-eye-view camera system that combines input from three cameras into a surround-view image of the machine and surroundings to provide improved operator situational awareness.

Furthermore, Komtrax and the machine’s monitor panel deliver machine data for monitoring and quick operator action. Komtrax, Komatsu’s remote monitoring system, now include an operator ID system, that provides data to track operators, applications and machine operation for up to 100 ID codes.

For operator comfort, the hydraulic excavator includes a standard high capacity, high back, heated, air-ride seat; selectable, auxiliary hydraulic control option provides one way and two-way attachment flow in the monitor panel, with adjustable flow control; Upgraded high-resolution, LCD colour monitor panel that incorporates the standard rearview camera display with gauges; and an auxiliary jack to connect mp3 players or other digital devices.

For easy maintenance, the PC238USLC-11 features ground-level access to engine oil and filters, DEF fill, as well as air filter and swing-out coolers.
