3) Operating the Elevator
Since the elevator has been previously operated
without material, it may now be tested under
load. It is suggested that the flow systems be
checked next. Allow only a small amount of grain
to enter the elevator when it is running. Check
that the material can flow through the system,
connections, valves, distributors, etc. After all
flow paths have been checked, the elevator may
be loaded to capacity.
4) Check the Elevator for:
a) Back-legging (grain returning down the
leg).
b) Head pulley slippage.
c) Proper cup filling.
d) Electrical current draw on the motor.
5) An elevator inspection is
recommended after the first 8-10
hours of operation.
Inspect each of the following:
a) Check all bolts holding the cups to the
belt for tightness.
b) Make certain the belt is running in the
center of the leg past the inspection station.
c) Inspect motor drive for looseness of
pulleys, sprockets, belts, chains or torque
arm.
d) Check for oil leakage or overheating of
the gear reducer.
e) Head pulley hub bolts and set screws.
1) Start Up Inspection
Before operating the elevator, check all areas
for
SAFETY
and machine damage which could
happen during construction.
a) Has the leg been correctly plumbed, guy
cables tensioned, and cables secured from
loosening?
b) Check all set screws in drive sheaves,
head and boot pulleys, shaft bearings, and
gear reducer to make certain they are tight.
Follow
the torque recommendations of the
manufacturer(s)
.
c) Check lubrication of all bearings and gear
reducer.
d) Operate the elevator empty under power
for a period of time. Be certain cups are
traveling in the right direction. Be certain the
belt is running on center over the head and
boot pulleys.
Keep personnel away from
moving parts.
e) Install the hood, motor drive shields,
inspection section screen, door, all
covers/guards, and the boot clean-out
doors.
f) Review the possibility of vehicle
damage to leg or guy cables.
g) Children and unauthorized persons
should not have access to the electric
controls or the climbing ladder.
h) Are pits designed to prevent personal
injury?
i) Has the electrical equipment been
installed to meet safety codes? This
includes explosion proof equipment
where used.
2) Flow System Completion
To complete an elevator system, other connections
must be made to the leg. These will need to be
completed before placing the leg into service.
