Inspections Before Starting Work; Function / Operation - Columbus McKinnon Yalelift 360 Traduction De Mode D'emploi

ASSEMBLY
Shorten or extend the hand chain
Adjust the length of the hand chain so that
the distance of the lower end to the fl oor is
between 500 – 1000 mm.
Note: For safety reasons, hand chain links
may only be used once.
- Look for the non-welded link of the hand
chain, bend to open and discard it.
- Shorten or extend the chain to the required
length.
ATTENTION: Always remove or add an even
number of chain links.
- Use a new link to close the loose chain ends
by bending it (for extending the hand chain,
two new chain links are required).
ATTENTION: Do not twist hand chains while
fi tting.
INSPECTION BEFORE INITIAL
OPERATION
Prior to initial operation, before it is put
into operation again and after substantial
changes, the product including the supporting
structure must be inspected by a competent
person*. The inspection mainly consists of a
visual inspection and a function check. These
inspections are intended to establish that the
hoist is in a safe condition, has been set up
appropriately and is ready for operation and
that any defects or damage are detected and
eliminated, as required.
*Competent persons may be, for example, the
maintenance engineers of the manufacturer or
the supplier. However, the company may also
assign performance of the inspection to its
own appropriately trained specialist personnel.
Before putting the unit into operation,
check functioning of the chain drive in
unloaded condition.
INSPECTIONS BEFORE STARTING
WORK
Before starting work, inspect the unit including
the suspension, equipment and supporting
structure for visual defects, e. g. deformations,
superfi cial cracks, wear and corrosion marks.
In addition also test the brake and check that
the hoist and the load are correctly attached.
Checking the brake function
Before starting work, always check operation
of the brake:
To do this, lift, pull or tension and lower or
release a load over a short distance with the
unit. When the hand chain is released, the
load must be held in any position.
This check is intended to ensure that even
at temperatures below 0 °C, the brake disks
are not frozen. Repeat it at least twice, before
starting further work.
ATTENTION: If the brake does not function
properly, the unit must be immediately taken
out of service and the manufacturer must
be contacted!
Inspection of the attachment point
- The attachment point for the hoist must be
selected so that the supporting structure to
which it is to be fi tted has suffi cient stability
and to ensure that the expected forces can
be safely absorbed.
- The unit must align freely also under load
in order to avoid impermissible additional
loading.
- The selection and calculation of the appropri-
ate supporting structure are the responsibil-
ity of the operating company.
Inspection of the load chain
Inspect the load chain for suffi cient lubrication
and check for external defects, deformations,
superfi cial cracks, wear and corrosion marks.
Inspection of the chain stop
The chain stop must always be fi tted to the
loose chain end (Fig. 11). There must be no
wear or incorrect alignment.
Inspection of the top hook and load hook
The top and load hooks must be checked
for cracks, deformations, damage, wear and
corrosion marks. The safety latch must move
freely and be fully functioning.
Inspection of chain reeving in the
bottom block
All units with two or more chain falls must be
inspected before initial operation to ensure
that the load chain is not twisted or kinked.
The chains of hoists with two or more falls may
become twisted if the bottom block is rolled
over, for example (Fig. 10).
When replacing the chain, make sure that the
chain is reeved correctly (Fig. 12). The chain
weld must face outwards.
Only fi t load chains which have been approved
by the manufacturer. Non-compliance with this
specifi cation will render the legal warranty or
guarantee void with immediate eff ect.

FUNCTION / OPERATION

Lifting the load
Pulling the hand chain (Fig. 11) in clockwise
direction will raise the load.
ATTENTION: Depending on the type of load
picked up, note that the lifting height may
be reduced for models with chain container!
Lowering the load
Pulling the hand chain (Fig. 11) in anticlock-
wise direction will lower the load.
Yale overload protection device
(optional)
The overload protection device is set to approx.
25% (±15%) overload. Its adjustment must only
be carried out by a competent person.
When the load limit is exceeded, the overload
protection device is activated and prevents fur-
ther lifting of the load, lowering is still possible.
INSPECTION, MAINTENANCE AND
REPAIR
According to national and international acci-
dent prevention and safety regulations hoisting
equipment must be inspected:
• in accordance with the risk assessment of
the operating company
• prior to initial operation
• before the unit is put into service again
following a shut down
• after substantial changes
• however, at least once per year, by a
competent person.
ATTENTION: Actual operating conditions (e.g.
operation in galvanizing facilities) can dictate
shorter inspection intervals.
Repair work may only be carried out by a spe-
cialist workshop that uses original Yale spare
parts. The inspection (mainly consisting of a
visual inspection and a function check) must
determine that all safety devices are complete
and fully operational and cover the condition
of the unit, suspension, equipment and sup-
porting structure with regard to damage, wear,
corrosion or any other alterations.
Initial operation and recurring inspections
must be documented (e.g. in the CMCO works
certifi cate of compliance).
If required, the results of inspections and ap-
propriate repairs must be verifi ed. If the hoist
(from 1 t lifting weight) is fi tted on or in a trolley
and if the hoist is used to move a lifted load
in one or several directions, the installation
is considered to be a crane and the further
inspections must be carried out, as required.
Paint damage should be touched up in order to
avoid corrosion. All joints and sliding surfaces
should be slightly greased. In the case of heavy
contamination, the unit must be cleaned.
The unit must be given a general overhaul
after 10 years, at the latest.
In particular, check the dimensions of the
load chain, the load hook and the top hook.
They must be compared with the dimensions
specifi ed in the table (Tab. 2, Tab. 3).
