“Regenerative air units all can exhaust some air through the fan housing exhaust door bleeder, anywhere from zero percent to 75 percent of the air the fan is producing,” he says. “The amount of air you exhaust determines the performance of the sweeper in various sweeping environments, but in the past the operator couldn’t tell how open that door was.”
So a standard Schwarze option for it’s A7000 Series of regenerative air sweepers includes an in-cab gauge that lets the operator know how open the door is. “Using the gauge the operator can not only see the position of the door but he adjusts the door using a simple toggle switch to get the maximum out of the unit. It enables the operator to react better and more quickly to sweeping conditions as they change.”
Sweeper Standby System
One problem encountered during street sweeping that’s not a problem with parking lot sweeping is the need to sometimes stop and sit while attempting to sweep a street. Whether it’s stopping for a red light or for pedestrians crossing the street, Hendrickson says sweeper operators are increasingly interested in Schwarze’s sweeper standby system.
“Quite simply, the option enables the operator to engage standby if they have to immediately stop the sweeping functions while sweeping their route,” Hendrickson says. “We initially made it available for just the gutter brooms but we’ve now incorporated the rest of the machine into the system.”
He says that with one switch the operator can raise the broom, raise the sweeper head, and lower the RPMs of the unit while he’s waiting to start sweeping again. When the operator is ready to begin moving again he simply reengages the standby option and the brooms are lowered and RPMs increase.
Operator Gauge Package
Giles says Elgin Sweeper is continually upgrading the amount of information available to the operator – and a recent option has made it easier for the operator to access it. “There’s so much going on in a sweeper that if we were to put it all on dials and gauges across the dashboard it would fill the whole dash,” Giles says. “So the current gauge package we offer collects and displays just a huge variety of information from the broom tilt angle to the amount of water in the tank and much more.”
Giles says the operator can scroll through information screens that provide the varied information and select the screens he wants to view and the information he wants to track—without there being too many gauges in front of him all the time.
“The ability to get information is becoming more and more important to the operator and now we’re able to provide more information in a smaller package,” he says.
