maintenance of the load chain
In most cases, chain wear in the link points
is caused by insufficient care of the chain. In
order to ensure optimal lubrication of the link
contact points, lubricate the chain at regular
intervals adapted to the application with creep-
type lubricant (e.g. gear oil).
A dry film lubricant, e.g. PTFE spray, should
be used in environments where abrasives like
sand, etc., occur.
The service life of the load chain can be in-
creased by careful lubrication to 20 - 30 times
compared with a chain that is not serviced.
- When lubricating the chain, make sure the
chain is in no-load condition so that the oil
can reach the contact points of the chain
links which are subject to wear. Chain link
parts contacting each other must always be
coated with lubricant, otherwise increased
wear on the chain results.
- It is not sufficient to lubricate the chains on
the outside as this does not ensure that a
lubricant film can build up in the contact
points.
- With a constant lifting path of the chain, the
change-over area from lifting to lowering
movement must be checked in particular.
- Make sure that the load chain is lubricated
over its entire length, also including the part
of the chain in the housing of the hoist.
- Clean dirty chains with petroleum or a similar
cleaning agent, never heat the chain.
- When lubricating the chain, also check the
chain for wear.
ATTEnTion:
It must be ensured that no lub-
ricant can penetrate into the brake enclosure.
This may result in failure of the brake.
Replacing the load chain
The load chain must be replaced by a new
chain of the same dimensions and quality in
the event of visible damage or deformations,
however, when the discarding status has been
reached, at the latest.
A load chain to be discarded must only be
replaced by an authorized specialist workshop.
Only fit load chains which have been approved
by the manufacturer. Non-compliance with this
specification will render the legal warranty or
guarantee void with immediate effect.
note: Replacement of a load chain must be
documented!
Hoist with single fall
- Only pull in the new chain in no-load condi-
tion.
- An open load chain link is required as a
tool. It can be obtained by using an abrasive
wheel to cut a section from an existing link
with the same dimension. The length of the
cut section must at least correspond to the
thickness of the link.
- Remove load hook from the old load chain
and suspend open load chain link in the
loose end of the load chain.
- Suspend the new, lubricated load chain also
in the open link and pull it through the hoist
unit (turn hand wheel clockwise).
- Do not fit a twisted chain. The welds must
face outwards from the chain wheel.
- When the old load chain has passed through
the hoist unit it can be detached together
with the open chain link and the load hook
can be fitted on the new load chain just
pulled in.
- Detach the chain stop from the loose end of
the old, replaced load chain and fit it to the
loose end of the new load chain just pulled
in.
ATTEnTion: The chain stop must always
be fitted to the loose end of the chain (idle
fall) (Fig. 11).
inspection of the load hook and top hook
Inspect the hook for deformation, damage,
surface cracks, wear and signs of corrosion,
as required, but at least once a year. Actual
operating conditions may also dictate shorter
inspection intervals.
Hooks that do not fulfil all requirements must
be replaced immediately. Welding on hooks,
e.g. to compensate for wear or damage is
not permissible. Top and/or load hooks must
be replaced when the mouth of the hook has
opened more than 10% (Fig. 14) or when the
nominal dimensions have reduced by 5% as
a result of wear.
Nominal dimensions and wear limits are
shown in table 3. If a limit value is reached,
replace the components.
inspection of the brake
Immediately contact the manufacturer, if
irregularities are found (e.g. defective friction
disks). All components of the brake must
be checked for wear, damage, discoloration
caused by overheating and for functioning.
Friction disks must always be kept free from
grease, oil, water or dirt. Check the bonding
of the friction disks.
Repairs may only be carried out by
authorized specialist workshops that
use original Yale spare parts.
After repairs have been carried out and
after extended periods of non-use, the hoist
must be inspected again before it is put into
service again.
the inspections have to be initiated by
the operating company.

observe the following for transporting
the unit:
• Do not drop or throw the unit, always deposit
it carefully.
• Load chains must be transported in a way
to avoid knotting and formation of loops.
• Use suitable transport means. These
depend on the local conditions.
observe the following for storing or
temporarily taking the unit out of
service:
• Store the unit at a clean and dry place.
• Protect the unit incl. all accessories against
contamination, humidity and damage by
means of a suitable cover.
• Protect hooks against corrosion.
• A light oil film should be applied to the chain.
ATTEnTion: It must be ensured that no
lubricant can penetrate into the brake enclo-
sure. This may result in failure of the brake.
• Since the brake disks may freeze at
temperature below 0 °C, the unit should
be stored with closed brake. For this pur-
pose, move the change-over lever to lifting
‚ ‘ and operate the hand lever with a
pumping action, while holding the load fall.
• If the unit is to be used again after it has
been taken out of service, it must first be
inspected again by a competent person.
Disposal:
After taking the unit out of service, recycle or
dispose of the parts of the unit in accordance
with the legal regulations.
