Design Allows Smaller Diesel with Less Onerous Controls
Illinois-based Elgin Sweeper is talking up its new three-wheel Pelican model with an “EcoInfused” design. Elgin meets John Deere 4045T Tier 4 Interim standards with a 55-kilowatt/74-horsepower 4045T diesel engine by John Deere – small enough that a particulate trap is not required, according to sweeper product manager Brian Giles.
The Deere 4045T operates 300 to 500 RPM faster on the new Pelican than on previous models, the manufacturer says, and a computer-controlled system matches propel speed to the available engine power.
The EcoInfused technology, Giles said in a release, “combines science and innovation to produce more environmentally efficient sweepers…
“This initiative represents years of unmatched innovation and success combining the science of alternative fuels, high-efficiency dust, debris and particulate removal, advanced filtration systems, improved horsepower management and water conservation technology.
Particulate Traps Are Costly
“This provides Elgin Sweeper contractor and municipal customers the ability to do more with less.”
Why shun the trap? “It is horribly complex, it is horribly expensive, it is horribly maintenance intensive,” Giles told F&F.
Elgin says it conducted high-altitude, high-temperature, hilly-terrain trials of the EcoInfused Pelican sweeper, and that 90% of operators felt that the new-design unit performed the same as their existing Pelican sweeper. They also found the new Pelican to be quieter, the manufacturer says.
