Never use the hook in a slanting position.
Do not operate jerkily as this provokes
deterioration of the equipment.
3. BRIEF DESCRIPTION OF HOIST
Do not constantly use the end stops as a means
of stopping.
Never use the lifting chain as a sling.
Never use the equipment as an earth for welding.
Do not use the equipment for a purpose or in a
situation for which it is not designed.
Never use the equipment to transport people.
Never attach a sling on the point of the hook (risk
of hook being damaged and load falling).
Do not use the safety devices as a means of
measuring laden weight.
Do not touch any moving parts.
Do not use the equipment for extracting or
unjamming purposes or for lateral pulling etc.
order to increase left or right travel to more than
would otherwise be possible.
Never use the equipment if it is in bad condition
(worn, bent, etc.).
Do not use spare parts of unknown or doubtful
origin.
Never intentionally allow the load to tip over.
Do not provoke violent impacts with the
equipment.
Never twist the lifting chain (risk of pulley block
turning over, etc.).
Do not leave a load suspended unless absolutely
necessary.
Never pull the load sideways, bring the equipment
to a position above the load before moving it.
- treated steel mechanisms : shafts, cogs,
sprockets,
- a lifting pulley
- an automatic self locking brake,
- a lifting chain,
- Provide fixed anchoring points whenever
possible.
- Oil the chains copiously along their entire length
and make sure they are not twisted.
- Ensure that the mechanical stop is fitted at 15
cm from the end of the chain.
- a chain guide case which guides the chain,
maintains it in the correct position and protects
the chain wheel,
The manual chain hoist for 250 to 2 000 kg is a
new concept in which esthetics have been
associated with reliability. It offers high security,
with lower weight and less upkeep.
- an galvanised manoeuvring chain.
The hoist is composed of :
4. INSTALLATION - COMMISSIONING
Carry out a dynamic test before commissioning :
- lifting and suspension hooks in treated steel
alloy with safety clips,
- Grease the hook swivel joints.
This test consists of using the hoist with load at all
working positions. Check that the hoist functions
correctly and that there is no distortion. Carry out
a complete manoeuvre, lifting a load
corresponding to the hoist's maximum safe load
multiplied by a coefficient of 1.1.
5. UTILISATION
The hoist you have just acquired must only be
used for a maximum load equal to the nominal
load indicated on the apparatus.
- Carry out several raising and lowering
operations using the entire length of the chain
with no load.
6. PRECAUTIONS
- to not stand in a position where breakage of the
chain may result in personnal injury,
- that no overload is likely to be caused by
adhesion to the ground, jamming, etc.
posi-tioning of other parts are not designed for
this type of operation. Such use is particularly
unsuitable for block and pulley type equipment.
- that the lifting chain is in perfect condition and
properly oiled,
- to initially lift the load with caution to check that
the slings are adequate and correctly positioned,
to stop the manoeuvre if the effort required on the
chain is greater than normal as the equipment is
7. MAINTENANCE
Always keep the chain clean and free of debris.
Clean as necessary with paraffin or diesel, drain
Before lifting a load, check :
- that the lifting chain is correctly fitted and not
twisted, especially on equipment fitted with pulley
The use of the hoists for horizontal or oblique
traction is forbidden as the chain guides and the
During lifting, it is advisable :
to limit loads to half of the nominal load capacity
during periods of cold weather (-15 ° C),
Since the simultaneous use of several hoists to lift
the same load is a particularly dangerous
manoeuvre, it should only be carried out in the
presence of a specially qualified person able to
accept full responsability unless the devices used
have been approved by your supplier or by a
representative of a Quality Control Organisation.
and re-oil. Do not clean the chain with thinners or
degreasing agents under any circumstances.
almost certainly overloaded.
blocks,
- that the load is not greater than the limit marked
