Hopper Dump Door
The
Hopper Dump Door
on the bottom of
the hopper opens to allow the hopper to be
emptied.
Hopper Dump Door Actuator
The electric
Hopper Dump Door Actuator
is pinned to the
Hopper Lift Weldment
and
Hopper Dump Door
and opens and closes
the
Hopper Dump Door
.
The
Spring and Yoke
on the rod end of
the
Hopper Dump Door Actuator
allow the
Hopper Dump Door
to move a short distance
toward the closed position when the
Hopper Dump Door
is open. This is designed
to prevent machine damage if the machine
is backed away from a dumpster and the
Hopper Dump Door
catches on or contacts
the dumpster.
Caution: The Spring is pre-compressed about an inch, so use caution if you ever need to
disassemble the Spring from the Yoke.
Dump Door Extend and Retract Limit Switches
The
Dump Door Retract
and
Dump Door
Extend Limit Switches
are proximity sensors
that sense when the hopper dump door is
open (retracted) and closed (extended).
Note that:
• The
Dump Door Extend Limit Switch
senses the
Dump Door Actuator Yoke
when the dump door is closed.
• The
Dump Door Retract Limit Switch
senses the dump door itself when the
door is open.
