New Caterpillar(R) 308C CR Hydraulic Excavator Delivers Performance and Versatility in Tight Spaces


Caterpillar introduces the 308C CR hydraulic excavator, a compact radius version of the 307C. Designed for urban contractors, and others who work in space-restricted applications, the 308C CR works productively in areas as narrow as 9 feet 8 inches (2.85 m). The new machine features high performance, excellent controllability, a comfortable operator station and extended service intervals.

The 308C CR weighs up to 17,730 lb (8040 kg), depending on how it is equipped, and produces 54 net horsepower (41 kW). A versatile machine, it accommodates two stick sizes, four bucket options, two blade widths and a variety of work tools. When equipped with the long stick, the excavator has a digging depth of 15 feet 5 inches (4.69 m). Tail swing radius is a mere 4 feet 3 inches (1.29 m).

Efficient power, precise control, low fuel consumption

An open-center, two-pump hydraulic system provides high efficiency and outstanding control. The hydraulic system uses each of the main pumps to 100 percent of engine power under all operating conditions, resulting in fast implement speeds and pivot turns. Pump flow decreases automatically when controls are in neutral to minimize fuel consumption and sound levels. A stick regeneration circuit conserves energy while the stick is in use, shortening cycle times and lowering operating costs. A boom drift reducing valve limits drift when material is suspended, improving efficiency and productivity. An auxiliary hydraulic valve is standard on the 308C CR, allowing easy field installation of work tools. Three auxiliary hydraulic arrangement choices enhance flexibility.

The 308C CR is powered by a naturally aspirated four-cylinder diesel engine. Developed for construction applications, the engine features long-stroke piston movement for high torque at medium to low speeds, excellent fuel efficiency, low sound levels and reduced vibration.

Comfortable work environment

The cab on the 308C CR is spacious and quiet, enhancing operator comfort and productivity. A sliding door offers easy entry and exit when working in tight quarters. An automatic climate control system and a front windshield that can be opened and closed with one touch keep the cab well ventilated. Ergonomically designed consoles and low-effort controls allow the operator to work comfortably and focus on production all shift long.

Reduced maintenance time

Key maintenance and service intervals on the 308C CR have been extended to improve machine availability and reduce operating costs. By using a new type of bearings, the front linkage greasing interval has been extended to 1,000 hours, except in bucket areas. Daily maintenance can be performed quickly and accurately because critical check points are grouped on the left side of the machine and are accessible from the ground.

The 308C CR is a versatile excavator that will work productively and economically in space-restricted applications. For more information, customers should contact their local Caterpillar dealer or visit the Cat web site at www.cat.com.
