The operation of an overhead hoist involves more than activating the hoist’s controls. Per the ANSI/ASME B30
standards, the use of an overhead hoist is subject to certain hazards that cannot be mitigated by engineered features,
but only by the exercise of intelligence, care, common sense, and experience in anticipating the effects and results of
activating the hoist’s controls. Use this guidance in conjunction with other warnings, cautions, and notices in this manual
to govern the operation and use of your overhead hoist.
4.2
Shall’s and Shall Not’s for Operation
Improper operation of a hoist can create a potentially hazardous
situation which, if not avoided, could result in death or serious injury,
and substantial property damage. To avoid such a potentially
hazardous situation

Section 3.11
).
•
NOT
use the hoist to lift, support, or transport
people.
•
NOT
lift loads over people.
•
NOT
apply load unless load chain is properly
seated in the load sheave (and idle sheave for hoist

•
NOT
use the hoist in such a way that could result in
shock or impact loads being applied to the hoist.
•
NOT
attempt to lengthen the load chain or repair
damaged load chain.
•
NOT
operate hoist when it is restricted from forming
a straight line from hook to hook in the direction of
loading.
•
NOT
use load chain as a sling or wrap load chain
around load.
•
NOT
apply the load to the tip of the hook or to the
hook latch.
•
NOT
apply load if binding prevents equal loading
on all load supporting chains.
•
NOT
operate beyond the limits of the load chain
travel.
•
NOT
operate hoist with missing/damaged chain
springs, shock absorbers, stoppers, striker plates or
limit locks.
•
NOT
leave load supported by the hoist unattended
unless specific precautions have been taken.
•
