Volvo has extended its C-Series excavator range with models spanning weight classes between 25 and 49 tonnes (27.5 to 53.9 short tons). A new Volvo, Tier-III-compliant engine is tuned for high torque at low revs for fuel efficiency. The onboard computer balances maximum available power to hydraulic output, preventing the engine from becoming overloaded (regardless of engine speed or pump demand). The new Care Cab gives operators more space, better climate control, better visibility, and controls that are easier to use.
