Komatsu’s PC138USLC-8 Series Hydraulic Excavators have a short tail swing profile,
designed specifically for work in confined areas. By reducing tail swing, the PC138USLC-8 is perfect for work on roadways, bridges, in urban areas, or anywhere space is limited. The PC138USLC-8 Series provides the performance and productivity you expect from Komatsu equipment.

Ecology and Economy Features:

• Low Emission Engine
A powerful turbocharged and air-to-air aftercooled Komatsu SAA4D95LE-5 engine provides 68 kW 92 HP (net). This engine is EPA Tier 3 emissions ready, without sacrificing power or machine productivity.

• Low Operational Noise
The dynamic noise is reduced providing low noise operation.

Productivity Features:

• High Mobility
— Large drawbar pull and steering force are evident when operating on a slope or other rough terrain.
— The machine travel speed changes automatically to Hi or Lo at optimal points according to the travel load.

• High Stability
The PC138USLC-8 offers exceptional lifting capacity and high stability with a large counterweight.

• Mode Selection
Five working modes designed to match engine speed, pump delivery, and system pressure.

Upper Structure Features:
• Slip resistant surfaces for improving foot traction
• Rear view camera

Excellent Reliability and Durability:
• High rigidity work equipment
• Sturdy frame structure
• Reliable Komatsu manufactured major components

KOMTRAX® equipped machines can send location, SMR and operation maps to a secure website utilizing wireless technology. Machines also relay error codes, cautions, maintenance items, fuel levels, and much more.

Operational Features
• Small Tail Swing
— Excellent operation in tight quarters is improved due to the small tail swing radius design
— Round profile provides short protrusion of front and rear portions of the upper structure.
— Occupies a small road width for operation in congested areas. — Wider Working Ranges: Job sites that require a long attachment reach, such as demolition and slope cutting, also benefit from the increased digging and dumping ranges of the PC138USLC-8.

Large TFT LCD Monitor:
• Easy-to-see and use 7" large multi-function color monitor
• Can be displayed in 12 languages

TFT : Thin Film Transistor
LCD : Liquid Crystal Display

Easy Maintenance
• Long replacement interval of hydraulic oil and hydraulic filter
• Remote mounted engine oil filter and fuel drain valve for easy access
• Equipped with the fuel pre-filter as standard (with water separator)
• Side-by-side cooling concept enables servicing of individual cooling modules.
• Equipped with the Equipment Management Monitoring System (EMMS).

Larger Comfortable Cab
• Low noise cab design with viscous cab mounting
• Sliding convex door facilitates easy entrance in confined areas.
• Large cab improves working space.
