Hopper System
Functional Description
Overview
The hopper system holds the dust and debris swept up by the brooms.
There are two different hopper congurations; a manual dump (MD) hopper and a variable dump (VD)
hopper.
• The manual dump hopper is xed. A manual dump lever opens a hopper ap to empty the hopper onto the
oor below the machine. Machines with a manual dump hopper do not have a dust control system.
• The variable dump hopper has a hydraulic cylinder that raises the hopper for emptying into a dumpster
or other receptacle. A second hydraulic cylinder opens and closes the hopper dump door. Machines
equipped with a variable dump hopper are also equipped with a dust control system. The dust control
system includes a hopper lter, dust control motor and impeller, and lter shaker motor. Refer to the
Dust Control System section for more information on the dust control components.
