OPERATING INSTRUCTIONS
Description
This electric chain hoist features self-locking, hardened steel
gears that also function
as
a brake. The hoist is equipped with
electronic overload protection, adjustable upper and lower limit
switches, permanently lubricated and hardened steel gear train,
and three-wire pendant control.
General Safety Information
This hoist is designed for safe operation within the limits
of
its
rated capacity. There are safety features built into the hoist to
protect the operator and others from injury due to failure
ofthe
hoist itself. However, listed below are safety precautions which
must be followed
in
order to protect personnel and property.
1.
Align hoistfor straightlinepull. Avoidsidepullsandpulling
horizontal!
y.
2.
Limitswitches are emergencydevices only. Donot uselimit
switches to stop the hoist
in
normal operation. Repeated
actuation
of
these limit switches under load could damage
the hoist.
3.
Donot operatehoistwith twisted, kinked,
or
damagedchain.
4.
Do not operate a damaged or malfunctioning hoist until
adjustments or repairs have been made.
5. Do not use hoist
to
lift people or carry loads over people.
6. Do not lift more than rated capacity
of
the hoist.
7.
Do not leave a load suspended in the air unattended.
8.
Avoid jogging controls or quick reversals
of
load.
9.
Alwaysremoveloadanddisconnecthoistfrompowersupply
before making repairs.
10.
Read ANSI Safety Standard B30.16
IAWARNINGIDO NOTUSEHOISTFOR

DO
NOT
OPERATE
HOIST
.IN AN
EXPLOSIVE
ATMOSPHERE OR CORROSIVE ENVIRONMENT.
II.
Do not replacechain supplied with hoistwith any othertype.
12.
Do not attempt to operate hoist on any other power supply
other than 115 volt, 50/60 Hz, single phase.

INSTALLATION
Mounting
The hoist must be hung by the upper hook only, and should not
be mounted by any other means. The mounting support must
be
capable
of
handling loads in excess
of
hoist rating. Suggested
locations are on a support beam or trolley.
Electrical Connection
This hoistis to be connected to a lIS-voltA.C., single phase. 50/
60
Hz current only. The outlet must be grounded.
Limit Switches
Thehoist is equipped with an upper and lowerlimit switch. The
upper switch is intended as an emergency shut-off to limit the
upward travel
of
the load hook and should not be used during
normal operation
of
the hoist. The lower limit switch is also
intended as an "emergency only" stop and should not be used
during normal operation
of
the hoist. Repeated use
of
the upper
and lower limit switch under load can cause shock loads that
could damage the hoist.
If
one
ofthe
limit switches has been activated. do not attempt to
continue hoist movement in the same direction. Hoist must
be
reversed. Continuedattempts to operate the hoistin the direction
ofthe
activated limit will break limit switch arm. A broken arm
on limit switch is not covered by warranty.
Chain Bucket
A chain bucket is standard equipment and may be used when
slackchain hanging from hoist is notdesired. Note how the hook
is fastened to the bucketbeforeremoving itfor installation
on
the
hoist. To install, feed the hook through the third link down
of
the
fixed chain end. Attach hookto the bucketby inserting hookends
through the
TOP
of
the tabs at the bucket rim.
OPERATION
This hoist is operated by the pendant station at the
end
of
the
control cord.
To
raise a load, press the button marked "...." (up).
To
lower
a
load.pressthe button marked "
...
" (down).
The
load will
stop
and
hold from either direction
by
releasing the button.
A load, whetherbeingraisedorlowered, will stopin approximately
I/S inch when the push button is released.
At
this point, the
motor
andface gearsarelockedand the load will remain in position until
the control switch is again activated.
Duty Cycle
This
is
an
intermittent
duty
hoisL Exceeding this duty
cycle
will causeoverheating
of
the gearboxandthe motor.
Overheated
gears thin out the lubricant causing excessive wear on the gears.
An overheated motor breaks down insulation on the
winding
causing premature motor failure. A temperature sensing device
built into the hoist will indicate
if
the duty cycle
has
been
exceeded.
EXCEEDING
THE
DUTY
CYCLE
VOIDS
THE
WARRANTY.
Therefore, it is very importanttoallow sufficient
time for the
motor
and gear box to cool
down
after
each
usage.
The
following chartgives recommended rest periods for varying
amounts
of
usage.
Do
not operate the hoist over 2
minutes
at
full load.

Trouble Shooting
If
hoist operates in one direction only,
check
for
ajammed

switcharm. Thiscan bedone by removing thelimitswitchcover.
If
hoist starts to lift a heavy load
and
then stops,
check
the
overload light while pressing the "...." button.
If
the
light
comes
on, then lower and reduce the load and repeat the procedure.
MAINTENANCE
On
a daily basis, the following should
be
checked:
1.
Controls-
Check
all controls and operating
mechanisms
for
proper function.
2. Safety Devices -Check upper
and
lower
limit
switches
for
proper function.
3. Hooks -
Check
for cracks
or
deformation.
4. Chain -Inspect for wear, distortion,
and
proper
attachment
ateachend.
Check
fordirt
and
foreign
matter
onchain thatcan
be carried
back
into hoist.
On
a periodic basis (suggested intervals
of
one
to
three months,
depending on service), the following should
be
checked:
4
I.
Bolts, screws, and connections
for
any loosening.
2. Pocket wheel for wear.
3.
Wear
of
chain. including chain stretch. Chain stretch can be
checked
by
measuring
11
links (inside to inside)
of
a section
of
chain that normally runs
over
the pocket wheel.
This hoist is equipped with a 4
MM
welded link chain with
a .472 nom. pitch; therefore,
11
links
of
a new chain should
measure 5.197 +.016
-.008
inches.
If
any
11
links
of
chain
measure
more
than 5.275 inches.
then stretch
and
wear is excessive
and
the chain must be
replaced.
4. Hooks -
Check
for
cracks
with
dye
penetrants, magnetic
particles.
or
other
suitable methods at least once a year.
5.
Check
electrical
components
for corrosion
or
other signs
of
deterioration.
6.
Check
hook
retaining pins for
wear
and
secureness.
Testing
After
repair,
check
to see that the welds on each chain link face
away from the pocket wheel. After repair
or
modification
of
a
hoist. itmust
be
testedfor
proper
operation. Begintest with a light
load and increase to rated capacity. Test should also include
operation
of
upper and lower limit switch.
Lubrication
If
lubrication
of
the
gearbox is required because
of
unusual
conditions, then use only
grease
Part No. 911502000. This is the
only grease
approved
for use in the hoist.
The
chain should
be
lubricated with
SAE
20-30
grade motor oil.
