We recently completed an appraisal for street sweepers – an industry that is really cleaning up. There are two main types of sweepers – regenerative air and mechanical broom. Each has advantages depending on application, for example, the type of debris that is being collected, the shape of the street or parking lot (i.e. crowned, flat), dumping preferences (i.e. remote, ground level or higher). These variables will dictate which type of sweeper is more suited for a particular application. Elgin is the largest street sweeper equipment supplier in North America, accounting for over 50% of all new sales. Tymco is another popular brand and has had success with several longstanding model designs over the past 20 years. Cleaner, “greener” street sweepers powered by CNG are witnessing growing adoption and leading sweeper manufacturers now offer alternative fuel powered vehicles. Sweeper manufacturers mount their systems on truck body chassis sourced from major manufacturers. Most units are mounted on medium or heavy-duty chassis. Commonly used chassis include International 4300, Freightliner M2 and Isuzu NPR Series. Systems are mounted on both conventional and cab-over style chassis.
