52 - Hopper System
Functional Description
Overview
The hopper system holds the dirt, dust and debris
swept up by the brooms. The hydraulic lift cylinder
raises the hopper to allow the accumulated dirt
and debris to be dumped into a suitable receptacle,
then lowers the hopper back down into the normal
operating position. The hopper lift cylinder is
powered by a separate hydraulic power pack that
includes an electric motor and hydraulic pump.
The hopper dump door, driven by an electric
actuator, can be opened by pressing the hopper
door open button when the hopper is up to empty
the hopper. A proximity sensor detects when the
hopper dump door is closed. The actuator contains
a position potentiometer to let the Main Controller
know the distance the actuator has traveled for the
door open position. The controller then turns off the
actuator motor. Note that the hopper door opens
automatically to receive the dirt and debris from the
brooms when the hopper is in the operating position
and the sweep system is enabled. Once the sweep
system is switched off, the hopper door closes. The controller will not permit the dump door to be manually
opened when the hopper is in the down position.
