Volvo Construction Equipment, Asheville, N.C., has announced the debut of its EC250D and EC300D excavators. The new excavators are heavy- duty machines that weigh 54,230 to 61,730 pounds (24.6 to 28 metric tons) and 66,140 to 73,630 pounds (30 to 33 metric tons) respectively.
According to a press release, the company says it designed the EC250D and EC300D excavators to offer improvements in fuel efficiency by between 9 to 13 percent. Both machines are fitted with Tier 4i- certified Volvo D8H engines, intended to produce lower emissions and high fuel efficiency. The engines include a waste-gate turbo, externally cooled exhaust gas re-circulation (EGR) and a combination of diesel oxygen catalyst (DOC) and diesel particulate filters (DPF) with partial fuel burner and active regeneration, according to Volvo. Maximum power is 202 horsepower for the EC250D and 227 horsepower for the EC300D.
Operators can choose from five working modes, including idle, fine, general and heavy. Performance can be further matched to the task by an attachment management system, which stores up to 18 different attachment presets. This allows hydraulic flow and pressure adjustments to be accurately set with a touch of a button, according to the company.
