all persons who will install, operate and maintain the Chain Hoist. !
Read thoroughly the contents before use and retain this handbook
for future use for safe, dependable and economical operation.Chain Hoist Safety procedures
1.Precautions before installation
a)Inspect carefully for any damage that may
occur during shipping. Check for
loose, missing, or damaged parts.
b)Confirm that the structure supporting the
hoist is strong enough to support the
rated capacity of the hoist with a
generous factor of safety.
2.Precautions before use
a)Confirm that the load chain is not twisted,
kinked, damaged or worn. The load
chain must always mesh correctly
with the load sheave. With 5 ton and
larger hoist, i.e. hoist with more
than 1-fall of load chain, twists can
arise by tuming over the bottom
hook through the load chain.
b)Lubricate the whole length of the load
chain with machine or gear oil.
c)Confirm that the brake is functioning
properly. Hoist the load 10 cm, next
check the brake when lowering the
load. When the hand chain is
released, the chain has to stop at
once.
3.Precaution during use
a)Never lift loads in excess of the rated
capacity marked on the hoist.
b)Never walk or work under a hoisted load
and never lift, support, or transport
people.
c)The hand chain is equipped with a safety
link. When the safety link opens or
deforms, stop at once and inspect
for the cause.
d)Do not operate hoist with other than
manual power.
e)Do not permit more than one operator to
pull on a single hand chain at one
time.
ALift loads correctly with proper slings and
attachments. Never lift with the
point of the hook and never use the
load chain as a sling by back
hooking.g)Lifting a load with two hoist is not
recommended. If the operation is
unavoidable, hoist the load with
utmost care, keeping balance of the
load.
h)Never run the load chain out too far.
‘When operated beyond the range of
lift, an excessive load that can cause
damage will be imposed on the
hoist.
i)Hoists are designed for lifting loads
vertically and should not be used for
horizontal or angle hoisting.
Extreme temperatures will lower the
toughness of the hoist. Loads should
be hoisted or lowered very slowly
and carefully.
k)Never leave a load hanging on the hoist.
1)The hoisting operation should never be
done with the hook caught to a
stationary object.
m)Never use the chain or hook as a ground
for welding.
n)Use only genuine parts and chains
supplied by the authorized
distributors.
4.Maintenance
After use, service the hoist before storing it.
Servicing and repairs should only be carried
out by qualified competent responsible
people.
a)Clean the hoist thoroughly.
b)Keep the hoist well lubricated. Oil the
load chain, hook shank and guideroller.
c)Store the hoist correctly against rain and
moisture. When the hoist is installed
outdoors, exceptional care should be
taken for maintenance.
5.Periodic inspections
Periodic inspection and lubrication in
accordance to the frequency of use must be
carried out to ensure long and safe operation
of the hoist. It is also recommended that a
record of maintenance be kept.
6.Chains and Hooks
a)The hooks and load chains are made of
special alloy steels and are precisely
heattreated. Never weld or heattreat
them again.
b)Load Chain
The load chains are exceptionally long
wearing, but wear is unavoidable
and certain conditions will cause
wear and corrosion that will lower
the strength. Load chains wom
beyond the permissible limits shown
in the Table 1 must be replaced at
once.
c)Hooks
The hook opening will elongate with
overloads and incorrect hooking.
When the hook opening is elongated
beyond the permissible limits shown
in the Table 2, it is dangerously
deformed and must be replaced
immediately.
