• 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
(LIFTING chain movement).
• 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.
• Fix the end of the idle fall of the new load chain on the housing or frame (depending on
model) of the hoist.
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 (chain movement UP).
• 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.
• Fix the loose end of the idle fall on the hoist instead of the old load chain.
ATTENTION: The loose end of the idle fall must always be fitted to the chain stop (Fig.
1).
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% 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.
