Powerful and environmentally friendly

Higher productivity

PC138US-11 is fast and precise. It features a powerful Komatsu EU Stage IV diesel engine, Komatsu load-sensing “closed center” hydraulic system (CLSS) and premium Komatsu comfort that delivers fast response and unmatched productivity in its class.

Komatsu fuel-saving technology

The fuel consumption of PC138US-11 has been reduced by up to 5%. Engine control has been improved. The variable speed adaptation to the engine and hydraulic pumps guarantees efficiency and precision both during single movements and combined movements.

Adjustable auto idle stop

To reduce unnecessary fuel consumption and exhaust emissions, as well as to reduce operating costs, Komatsu’s auto idle stop will automatically stop the engine after it has been idling for a certain period. It can easily be programmed from 5 to 60 minutes. An eco-meter and eco-tips on the screen in the cab further contribute for efficient operation.

Superb usability

Ideal for a wide range of applications

Komatsu PC138US-11 is equipped to perform all kinds of tasks, in an efficient manner. On small or large facilities, for digging, ditching, landscaping or site work, Komatsu’s hydraulic system always ensures maximum productivity and control.

6 work functions

Power, Lift, Hammer, Economy, Implements Power, and Implement Economy are available features that ensure that the PC138US-11 delivers the performance you need with minimal fuel consumption. The economy function can be adjusted for ideal balance between power and economy, to suit your current work. The amount of oil delivered to hydraulic implements can be adjusted directly on the large screen.

Large selection of accessories

With many available options – such as belt plates for asphalt or shear – you can equip your PC138US-11 so that it can handle special needs during transport, workplace, or tasks.

Built-in versatility

A standard-mounted hydraulic circuit controlled by a joystick slider and a floor-mounted pedal gives the PC138US-11 superb versatility. There are 10 memory settings for implements, which can be stored with custom names. In combination with standard equipment circuit for HK attachment, changing equipment is now even easier. An additional hydraulic circuit is available for equipment that requires an additional hydraulic function.

Short hedge and superb stability

PC138US-11 has a rounded shape with minimal protrusions both front and rear. The very short turning radius at the rear is perfect for work in tight spaces, especially in densely populated areas or on roads, during forestry work and demolition work. Thanks to optimal solutions, the PC138US-11 is extremely stable. Along with the machine’s large range makes this stability machine ideal for work that requires long range, such as demolition work and slope work. With sufficient reach for unloading during loading work, the operator can always work easily, efficiently and completely relaxed.

Top class comfort

Increased comfort

In the wide Komatsu SpaceCab- cabin, the air-spring seat has a high back standard, with warmth for increased comfort and with fully adjustable armrests. It is the optimal center for a comfortable and less tiring work environment. Ergonomically and logically designed levers and switches further contribute to increasing the driver’s productivity to the maximum.

Perfect driver environment

In addition to the DAB + radio, the PC138US-11 has an additional input for connecting external devices to play music through the speakers in the cabin. Two 12V power outlets are also available in the cabin. Proportional levers are fitted as standard for safe and precise operation of implements.

Low noise construction

Komatsu crawler excavators have very low external noise levels and are particularly suitable for work in tight spaces and densely populated areas. Optimal use of noise-absorbing and noise-absorbing materials helps to provide a very low internal noise level.

Information and communication technology

Widescreen format screen

The large screen can be easily adapted as of own choice and offers 26 different languages, simple buttons and multifunction keys that provide access to several different functions and operating information at your fingertips. The rear-view camera and level gauge for the AdBlue® tank is now incorporated in the standard display on the screen.

An envolving interface

Useful information is now easier than ever to find and understand with the upgraded screen interface. An optimal main screen for the current job can be selected by pressing the F3 key.
