Old post, but I had to answer. The city of Appleton, Wisconsin uses them. If fact I think they were the first and Elgen copied their plow. We will be putting the plows on the sweepers in a week or two ( first part of October) and we push all leaves and yard waste that's in the street to the corners or until we can no longer push with out it spilling out the sides. We do this at night. Crews with end loaders and garbage trucks then pick up our piles the next day and remove them. It works very, very well. PR
I have Wayne sweeper brochures from the 1950s and 60s that offered leaf plows to be mounted in the front of the Sweeper. The stated purpose was to avoid filling the hoppers with leaves instead of the usual debris.
I could see using that on a bottom dump sweeper but why on a Pelican? I guess if you dont mind the extra expense of a loader its not a bad idea. Around here we just pick em up with the sweeper. Would like to see a picture of one in operation though.
Diagonal Brace, we have about 350-400 miles of roadways that we sweep. All streets in the city are tree lined. When we do leaves, it takes five machines working nights pushing and sweeping. It also takes five or six loaders in the daytime to pick up what we pushed the night before. We do this for 5 to 7 weeks depending upon weather.
