Komatsu new PC138US-8 Crawler Excavator
22/10/2007

Komatsu were the inventors of the ultra-short-tail excavators. The 13-tonne PC138US-8 was designed for use on urban and roadside construction sites. As the latest in the company’s short tail swing machines, the PC138US-8 offers unrivalled machine management, operator comfort, safety, fuel efficiency and low environmental impact.

Like all machines in the Dash 8 range, the PC138US-8 is fitted with Komtrax, Komatsu’s Satellite Monitoring System. Machine data is easily accessible over the internet and allows owners or fleet managers to view the machines location, performance and service requirements. Komtrax can even help secure equipment, and will email the owner or fleet manager when a machine shows a caution alert or if it is activated outside an engine lock period.

Designed to offer total safety for both the operator and people around the machine, the PC138US-8 features Komatsu’s unique roll-over cab, specifically developed for hydraulic excavators. Over 1 million Euros were spent on testing this life saving feature, and the cab’s tubular steel frame protects the operator even if the machine rolls over. Furthermore, to help prevent accidents, the excavator includes a travel alarm, anti-slip steps and a rear-view camera   which are all standard.

With its optional heated air suspension seat, the cab provides a fantastic comfortable and quiet working environment with an in-cab noise level of just 72 dB(A). Standard on the PC138-8, is the largest full colour monitor panel on the market. This ergonomic finger tip controlled operating panel allows easy access to work modes, cab-climate control and a full colour image from the rear mounted camera.

Both the front and back of the excavator’s upper structure have a rounded profile, allowing the PC138US-8 to work easily and safely in confined areas or where obstacles are present. The PC138US-8 is available with optional blade assembly and rubber road liners. Quick coupler piping is fitted as standard to allow convenient and rapid changes of attachments. An extra attachment circuit is also fitted as standard, suitable for either crusher or breaker. As an option, an additional rotation circuit is available.

The operator can choose between 5 Working Modes to optimise performance and fuel usage. The Eco gauge on the right side of the monitor panel lets him see at a glance just how hard the machine is working. In Economy Mode, and with Komtrax activated, fuel usage can be easily monitored for maximum fuel efficiency and minimum nitrogen oxide (NOx) emissions.

The PC138US-8’s ecological credentials are further boosted by its powerful yet efficient SAA4D95LE-5 Komatsu engine. Part of Komatsu’s innovative ECOT3 range, this electronically controlled high-pressure common-rail engine is fully compliant with EU Stage IIIA emissions. The engine is very quiet to run and, together with a unique low noise design, ensures the PC138US-8 meets EU noise regulations with a dynamic external noise of just 100 dB(A).
