Volvo Construction Equipment, Shippensburg, Pennsylvania, has introduced a Tier 4 Final/Stage IV-compliant crawler excavator. The EC480E crawler excavator lowers operating costs through reduced fuel consumption and simple maintenance requirements, according to Volvo.
The EC480E is powered by a Tier 4 Final/Stage IV-compliant Volvo D13 engine, which allows the excavator to deliver high digging and breakout forces alongside reduced emissions and improved fuel efficiency.
Volvo says the full electro-hydraulics are matched to the engine and are controlled by an advanced system, which provides on-demand flow and reduces power losses within the circuit. The Volvo ECO mode contributes to the machine’s total improved efficiency without losing performance in most operating conditions, the company explains. As well as improving fuel efficiency, Volvo says this increases controllability for more precise performance.
The crawler excavator’s integrated work mode system offers the operator a choice of work modes according to the task at hand — including I (idle), F (fine), G (general) and H (heavy) — for efficiency and machine performance. When controls have been inactive for a pre-set amount of time, the excavator can be programmed to automatically reduce engine speed or shut down to reduce fuel consumption and noise. Operators can keep track of both current and average fuel consumption via a gauge in the cab.
The Volvo EC480E crawler excavator also has been designed for simple maintenance, the company says. The excavator’s three-piece undercarriage and high tensile steel X-shaped frame have been reinforced to ensure a long service life, while additional superstructure cover plates prevent damage to the underside of the machine from rock and debris. The chance of the equipment overheating is reduced due to a hydraulically-driven, electrically-controlled cooling fan, further minimizing fuel consumption and noise. The fan’s optional reverse functionality, which blows air in the opposite direction, enables self-cleaning for ease of maintenance.
Volvo says its general purpose buckets are ideal for digging and rehandling in soft to medium conditions, while heavy-duty buckets are designed for productive digging in compacted materials. A selection of economic, replaceable wear parts, including high-quality teeth, segments, side cutters, adapters and shrouds, also are available to protect the bucket and ensure long life.
