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 THE OPERATOR SHALL:
• NOT lift more than rated load for the hoist.
• NOT operate unless load is centered under hoist.
• NOT use damaged hoist or hoist that is not working
properly.
• NOT use hoist with twisted, kinked, damaged, or
worn chain.
• NOT use hoist if the bottom hook is capsized
(double fall hoists - see Section 3.2 ).
• 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
with two chain falls).
• 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, cushion rubbers, stoppers or striker plates.

warnings.
• Make sure the unit is securely attached to a
suitable support before applying load.
• Make sure load slings or other approved single
attachments are properly sized, rigged, and seated
in the hook saddle.
• Take up slack carefully - make sure load is
balanced and load-holding action is secure before
continuing.
• Make sure all persons stay clear of the supported
load.
• Protect the hoist’s load chain from weld splatter or
other damaging contaminants.
• Report Malfunctions or unusual performances
(including unusual noises) of the hoist and remove
the hoist from service until the malfunction or
unusual performance is resolved.
• Make sure hoist limit switches function properly.
• Warn personnel before lifting or moving a load.
