PC138US-11E0 Komatsu excavator specs & Dimensions (2016 - 2022)

Monitor Interface

Helpful information is now easier than ever to find and understand with the upgraded monitor interface. An optimal main screen for the ongoing work can be selected simply by pressing the F3 key.

Optimal jobsite safety

Safety features on the Komatsu PC138US-11 comply with the latest industry standards and work in synergy to minimise risks to people in and around the machine. A neutral detection system for travel and work equipment levers increase jobsite safety, along with a seat belt caution indicator and an audible travel alarm. Highly durable anti-slip plates – with additional high friction covering – maintain long term traction performance.

Komatsu fuel-saving technology

Fuel consumption on the PC138US-11 is lower by up to 5%. Engine management is enhanced. The variable speed matching of the engine and hydraulic pumps guarantee efficiency and precision during single and combined movements.

Adjustable idle shutdown

The Komatsu auto idle shutdown automatically turns off the engine after it idles for a set period of time. This feature can easily be programmed from 5 to 60 minutes, to reduce unnecessary fuel consumption and exhaust emissions, and to lower operating costs. An Eco-gauge and the Eco guidance tips on the cab monitor further encourage efficient operations.

Noise Levels in Komatsu Excavators

Komatsu crawler excavators have very low external noise levels and are especially well-suited for work in confined spaces or urban areas. The optimal usage of sound insulation and of sound absorbing materials helps to make noise levels inside the cab comparable to those of an executive car.

Safe maintenance

Thermal guards around high temperature areas of the engine, protected fan belt and pulleys, a pump/engine partition that prevents hydraulic oil from spraying onto the engine, and exceptionally sturdy handrails: in Komatsu tradition, the highest safety level is provided for a fast and smooth maintenance.

Long-life oil filters

The Komatsu Genuine hydraulic oil filter uses high-performance filtering material for long replacement intervals, which significantly reduces maintenance costs.

Short tail swing and exceptional stability

The PC138US-11 has a rounded profile with minimal protrusions at both the front and the rear. Its ultra-short tail swing radius is perfect for work in tight spaces, particularly in urban areas, or for road construction, logging and demolition. Thanks to optimised packaging, the PC138US-11 is exceptionally stable. Coupled with the machine’s wide working range, this stability makes it ideal for any work requiring long reach, such as demolition jobs and slope cutting. With ample dumping reach available for loading operations, the operator can always work easily, efficiently and with absolute confidence.

A wide choice of options

With many options available – such as road-liner track shoes or a dozer blade – you can configure the PC138US-11 to match specific demands for transport, working envelope or duty.

Short tail swing radius

1,48 m – Because the tail of the PC138US-11 is more compact than conventional models, the PC138US-11 reduces the operator’s need to check behind him for movement.

Short implement swing radius

1,98 m – Boom raising angle of the PC138US-11 is larger than on a conventional profile excavator, while front implement protrusion is lessened.

Safe operation in confined areas

The machine’s rounded profile allows it to operate in narrow spaces or where there are a number of obstructions. The compact tail design minimises the risks of rear impact and lets the operator concentrate fully on his work.

First-Class Comfort

In the wide Komatsu SpaceCab™, a standard air-suspended high-back seat, heated for improved comfort and with fully adjustable armrests, is the centre of a comfortable and low-fatigue working environment. High visibility and ergonomic controls further assist to maximise the operator’s productivity. Conveniently customisable and with a choice of 26 languages, the widescreen monitor with simple switches and multifunction keys gives fingertip access to a large range of functions and operating info. The rear camera view and an AdBlue level gauge are now incorporated into the default main screen.

Rear-view camera

A standard fitment camera gives you an exceptionally clear view of the rear work zone on the widescreen monitor panel. This low profile camera is integrated into the counterweight’s shape and adjustable. On request, the KomVision system can be equipped.

Safe SpaceCab™

The cab is ROPS compliant with ISO 12117-2:2008. It has a tubular steel frame and provides very high shock absorbency, impact resistance and durability. The seat belt is designed to keep the operator in the safety zone of the cab in the event of a rollover. Optionally it can be fitted with an ISO 10262 Level 2 Falling Object Protective System (FOPS) with openable front guard.

KomVision (optional)

KomVision can display a 360 degree bird’s eye view representation of the machine on the standard monitor by using 3 cameras installed on the sides and rear of the machine.

Lifting Capacity

When removing bucket, linkage or cylinder, lifting capacities can be increased by their respective weights. With 500 mm shoes. Load is limited by hydraulic capacity rather than tipping. Ratings are based on SAE Standard No. J1097. Rated loads do not exceed 87% of hydraulic lift capacity or 75% of tipping load. Lifting capacity stated is based on lifting with bare arm. When lifting with additional equipment installed to the arm, please subtract the weight of all additional equipment from the values stated.
