Public Works' Hybrid Sweeper Scrubber 2016

Sweeper ScrubberIn 2016, Public Works purchased a new Advance CS7000 LPG Hybrid Sweeper Scrubber that is used to clean the Village parking garages.  Designed for indoor and outdoor operation, the propane-fueled engine produces up to 45% lower CO2 emissions per square foot, and has lower operation costs compared to other machines in its class. The complex and high maintenance hydraulic systems including the large hydraulic reservoirs, filters and oil coolers as well as 98% of the leak-prone hydraulic hoses, pumps, motors, and valves have been eliminated. Hydraulic drives have been replaced by an intelligent system of electronically controlled, low maintenance electric drives.  This technology shift alone will save thousands of dollars in maintenance costs.

Public Works' Hybrid Tower Truck 2017

Hybrid Tower TruckDrive Clean Chicago is an innovative incentive program aimed at creating a roadmap for a greater alternative fuel transportation network for Chicago. Given the fluctuation in fuel costs, vehicle emissions and the lack of infrastructure for alternative fuels, Drive Clean Chicago provides important incentives to help Chicago fleet owners purchase cleaner vehicles that are better for business and the environment.

In 2017, the Fleet Services Unit used this program to purchase a hybrid aerial truck from Altec Industries. The Altec JEMS (Jobsite Energy Management System) is an integrated plug-in system that uses stored electrical energy to power the aerial device, tools and exportable power, and provides cab comfort. The energy storage system is recharged by plugging into shore power or by the truck’s internal combustion engine.
