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. 12).
Hoist with several falls
ATTEnTion: Only pull in the new chain when
the bottom block is unloaded, otherwise the
bottom block may drop when the load chain
is detached. Danger of injury!
- 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.
- Detach the loaded-fall end of the load chain
from the housing of the hoist unit or the
bottom block (depending on model).
- Suspend prepared, open load chain link in
the now free load chain end.
- Suspend the new, lubricated load chain
also in the open link and pull it through the
bottom block and 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.
- Fix the loaded-fall end of the new load chain
on the housing/frame or on the bottom block
(depending on model) of the hoist.
- Attach the chain stop to the loose end of the
new load chain.

ATTEnTion: The loose end of the idle
fall must always be fitted to the chain stop
(Fig. 12).
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. 15) 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.

siONiNg AND DisPOsAL
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.
