VARIABLE SPEED ELECTRIC CHAIN HOIST WITH
OPTION
It is not recommended for use in any application where there is
a possibility of adding to an already suspended load to the point
of overload. This includes dumbwaiter (*see below) installations,
containers that are loaded in mid-air, etc.
(*) Refer to limitations on page 3 concerning dumbwaiter
applications.
2. All hoists are equipped with electronically programmable
limit switches, which automatically stop the hook at any
predetermined point when either hoisting or lowering.
3. Rated lifting speeds are shown on hoist identification plate.
SLOW speed is intended as a means of carefully controlling or
“spotting” the load, although the hoist may be operated solely at
this speed if desired. It is not necessary to operate in the SLOW
speed position as the hoist will pick up a capacity load at FAST
speed from a standing start. In other words, it is not necessary to
hesitate at the SLOW position when moving control from STOP
to FAST position or vice versa.
4. If material being handled must be immersed in water, pickling
baths, any liquid, or dusty or loose solids, use a sling chain
of ample length so that the hook is always above the surface.
Bearings in the hook block are shielded only against ordinary
atmospheric conditions.
HOIST
1. Before picking up a load, check to see that the hoist
is directly overhead.
When applying a load, it should be directly under hoist or trolley.
Avoid off-center loading of any kind.
2. Take up a slack load chain carefully and start load easily to
avoid shock and jerking of hoist load chain. If there is any
evidence of overloading, immediately lower the load and
remove the excess load.
3.
DO NOT
allow the load to swing or twist while hoisting.
4.
DO NOT
allow the load to bear against the hook latch.
HOIST WITH PUSH TROLLEY
This unit should be moved by pushing on the suspended load or
by pulling the empty hook. However, the unit can also be moved by
pulling on the control station since an internal steel cable extends
the length of the control cord and is anchored to the hoist and to the
control station.
HOIST WITH MOTOR DRIVEN TROLLEY
This unit should be moved by operating the controls marked
(Forward) and (Reverse) in control station. Unless altered by the
erector, depressing (Forward) control will move the hoist toward
motor housing end. Anticipate the stopping point and allow trolley
to coast to a smooth stop. Reversing or “plugging” to stop trolley
causes overheating of motor and swaying of load.
SAFE OPERATING INSTRUCTIONS AND
PROCEDURES
For safety precautions and a list of Do’s and Do Not’s for
safe operation of hoists, refer to page 3.
1. Permit only competent personnel to operate unit.
2. When preparing to lift a load, be sure that the attachments to the
hook are firmly seated in hook saddle. Avoid off-center loading
of any kind, especially loading on the point of hook.
3.
DO NOT
allow the load to bear against the hook latch. The latch
is to help maintain the hook in position while the chain is slack
before taking up slack chain.
Allowing the load to bear against the hook latch and/or hook tip
can result in loss of load.
TO AVOID INJURY:
Do not allow the load and/or attachments to bear against the hook
latch and/or hook tip. Apply load to hook bowl or saddle only.
4.
DO NOT
wrap the load chain around the load and hook onto
itself as a choker chain.
Doing this will result in:
a. The loss of the swivel effect of the hook, which could result in
twisted chain and a jammed liftwheel.
b. The upper limit switch is bypassed and the load could hit the
hoist.
c. The chain could be damaged at the hook.
5. Before lifting load, check for twists in the load chain.
On double- and triple-reeved units, a twist can occur if
the lower hook block has been capsized between the
strands of chain. Reverse the capsize to remove twist.
6. Stand clear of all loads and avoid moving a load over the heads
of other personnel. Warn personnel of your intentions to move a
load in their area.
7.
DO NOT
leave the load suspended in the air unattended.
8.
DO NOT
use this or any other overhead materials handling
equipment for lifting persons.
9.
DO NOT
load hoist beyond the rated capacity shown on ID
plate. When in doubt, use the next larger capacity CM Lodestar
Hoist.
10. Warn personnel of your intention to lift a load in the area. Tie off
the load with auxiliary chains or cables before access to the area
beneath the load is permitted.
11. Take up a slack load chain carefully and start load easily to
avoid shock and jerking of hoist load chain. If there is any
evidence of overloading, immediately lower the load and
remove the excess load.
12. When lifting, raise the load only enough to clear the floor or
support and check to be sure that the attachments to the
hook and load are firmly seated. Continue lift only after you are
assured the load is free of all obstructions.
13.
DO NOT
allow the load to swing or twist while hoisting.
14. Never operate the hoist when flammable materials or vapors
are present. Electrical devices produce arcs or sparks that can
cause a fire or explosion.
15.
STAY ALERT!
Watch what you are doing and use common
sense. Do not use the hoist when you are tired, distracted or
under the influence of drugs, alcohol or medication causing
diminished control.
THERMOCHROMIC LABELS
This hoist is equipped with special thermochromic labels that
change color in response to temperature. When the area under the
label exceeds 130°F, the label will transition from orange to white,
revealing the word “HOT.” When the hoist cools down, the warning
will disappear. Over time, the label may lose its effectiveness, and
eventually will always say “HOT.” For your own safety, always treat
any hoist parts as hot before handling them, and wear gloves when
handling a hoist that was recently in use.
