SSAM began the transition to electric in September 2012, partnering with Conductix-Wampfler to retrofit eight RTGs to e-RTGs. Over the next two and a half years, the operator worked to convert a total of 32 RTGs to electric and purchased four new e-RTGs from Chinese manufacturer ZPMC, all equipped with Conductix-Wampfler cable reels.
In order to complete the project, SSAM also converted four Paceco RTGs into RMGs for intermodal rail yard operations. Those units are powered with Conductix-Wampfler’s Hevi-Bar II Conductor Bar System.
“The transition to e-RTGs is a clear benefit no matter how you look at it,” commented Gabriel Juri of SSAM. “We are extremely satisfied with the performance of the e-RTGS, particularly due to the higher speeds and increased productivity from not having to refuel or conduct diesel engine maintenance.”
With the transition complete, SSAM said it is well on its way to increasing efficiency and cost savings while meeting all the latest environmental demands. The e-RTGs employ new technologies that greatly reduce emissions and enhance productivity, reliability and flexibility.
The new technology reduces fuel consumption by an estimated 95%. In addition, the e-RTGs are apparently more reliable than diesel-powered versions with less downtime. This reduction in both fuel demand and maintenance costs will mean a significant net savings each year for SSAM.
