Skanska has completed a 90-day pilot program using a Volvo EC230 Electric excavator on the Purple (D Line) Extension Transit Project in Los Angeles, at the South Yard of the La Brea station. This project is working to extend westward nine miles and add seven new stations.
The use of this zero-emissions equipment by Skanska was a part of the first series of pilot programs launched for the Volvo excavator in North America. The goal of this trial was to test the capability of a battery-powered excavator to perform the necessary construction work, particularly in relation to its diesel-powered counterpart.
The Volvo EC230 Electric excavator replaced a diesel-powered Komatsu PC228 excavator and was used to load trucks of export construction material from a stockpile. The 90-day trial indicated results showing the Volvo EC230 Electric could perform the necessary activities as intended while keeping the pace of work on schedule.
The results indicate reduced emissions and lowered costs overall. The unit reduced carbon per hour by 66 percent and saved an estimated 74 percent in cost per hour ($15.15).
The pilot showed additional benefits from a health and safety aspect. Using the electric excavator generated much less vibration and noise than a diesel-powered version. This creates a less exhaustive and better working environment for the operator and results in less construction noise for the surrounding community. Favorable feedback from operators also included its ease of use and capacity.
“Skanska is proud to be a part of this pilot with Volvo which can serve as a catalyst for the evolution and adoption of lower emission construction practices,” said Mason Ford, director of sustainability and equipment services for Skanska USA Civil. “Aligned with our commitment to a cleaner future, the successful completion of this pilot program represents a significant stride forward for the entire industry. Change doesn’t happen overnight, but this type of investigation into the possibilities furthers the conversation around electrification and sustainable innovation within civil construction.”
Sunbelt Rentals supplied the Volvo EC230 Electric demonstration unit to Skanska for the use in this pilot program.
