Volvo's New Tier 4 Final Crawler Excavators
The new Tier 4 Final/Stage IV-compliant EC250E and EC300E crawler excavators from Volvo deliver a 5 percent improvement in fuel efficiency over past models, saving users time and money. This improvement comes from the new engine and a range of features that optimize flow and minimize pressure losses in the hydraulic system, the company says.
One key is the engine's ECO mode, which automatically reduces fuel consumption without any loss of performance in most operating conditions. The operator can manually control flow to the hydraulics using the integrated work mode system or choose from a selection of work modes according to the demands of the task at hand. To reduce idle time, the excavators can be equipped with automatic idling and auto-engine shut down systems as optional equipment.
All interfaces — including the joysticks, keypad and LCD monitor — have been ergonomically designed and positioned for comfort, control and efficiency. For operator ease of use, the number of switches has been significantly reduced.
For a more productive work the proportional two-pump flow makes it easier for the operator to improve the machine’s controllability. The high pump flow combined with the electro-hydraulic control system also helps create faster response and cycle times. In addition, the EC300E features increased pump input torque for even faster cycle times. With the boom float function, the power pump for boom lowering can be saved or used for other functions, further reducing cycle times and making grading operations easier.
The attachment management system makes changing attachments faster, safer and easier. Controlled through the monitor the system stores settings for up to 20 different hydraulic attachments. The After Treatment Control Module (ACM) automatically controls, monitors and diagnoses the after treatment system to ensure emission regulation compliance.
