1. Choose the Right Hoist for the Job
Choose a hoist with the capacity for the job. Know
the capacities of your hoists and the weight of
y
our loads.
Then match them.
The application, the size and type of load, the
attachments to be used, and the period of use
must also be taken into consideration in selecting
t
he right hoist for the job.
Remember the hoist was designed to ease our
b
urden and carelessness not only endangers the
operator, but in many cases, a valuable load.
2. Inspect
A
ll hoists should be visually
inspected before use, in
addition to regular, periodic
m
aintenance inspections.
Inspect hoists for operation
warning notices and legibility.
Deficiencies should be noted
and brought to the attention of
s
upervisors. Be sure defective
hoists are tagged and taken out of service until
repairs are made.
Under no circumstances should you operate a
malfunctioning hoist.
Check for gouged, twisted, distorted links, and
foreign material. Do not operate hoists with
twisted, kinked, or damaged chain links.
Load chain should be properly lubricated.
Hooks that are bent, worn, or whose openings
are enlarged beyond normal throat opening
should not be used. If latch does not engage
throat opening of hook, hoist should be taken
out of service.
Chains should be checked for deposits of
foreign material which may be carried into
the hoist mechanism.
Check brake for evidence of slippage under load.
3. Use Hoist Properly
Be sure hoist is solidly held in the uppermost part
of the support hook arc.
Be sure hoist and load are in a straight line.
Do not pull at an angle.
Be sure load is hooked securely. Do not tip load
the hook. Do not load hook latch. Hook latch is to
prevent detachment of load under slack chain
conditions only.
Do not operate with hoist head resting against
any object. Lift the load gently. Do not jerk it.
4. Practice Caution Always
Do not lift co-workers with a hoist.
Make sure everyone is clear of the load when
you lift.
Do not remove or obscure operational warning
notices.
5. Operator Service
CLEANING: Hoists should be kept clean and free
of dust, dirt, moisture, etc., which will in
any way affect the operation or safety of
the equipment.
LUBRICATION: Chain should be
properly lubricated.
AFTER REPAIRS:
Carefully operate the
hoist before
returning it to full
service.
