• 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 specialist 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 supporting 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
certificate of compliance).
If required, the results of inspections and appropriate repairs must be verified. If the hoist (from
1 t lifting weight) is fitted 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.
For the models with gear drive, ensure that the drive shaft and geared wheels are sufficiently
greased at all times.
The unit must be given a general overhaul after 10 years, at the latest.
ATTENTION: After the replacement of components, a subsequent inspection by a
competent person is obligatory!
ATTENTION: Chains must only be replaced by chains of the same material, with the
same quality and the same dimensions.
Inspection of the clevis of the load bar
Inspect the clevis of the load bar 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.
If a clevis must be discarded as a result of an inspection, a new load bar must be fitted.
Welding on load bar and/or clevis, e.g. to compensate for wear or damage, is not permissible.
The load bar with clevis must be replaced at the latest, if the material diameter is 5% smaller
than the nominal diameter.
Replacing the hand chain (only trolley with gear drive)
• 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.
• Open the old hand chain (preferably on the connection link) and suspend the open link into
the loose end of the hand chain which lies "in front of" the hand chain wheel.
• Suspend the new hand chain also in the open link and pull it through the chain guides and
over the hand chain wheel.
• Do not fit a twisted chain. The welds must face outwards.
• Separate the old hand chain including the open connection link from the new hand chain and
connect the two loose ends of the new hand chain by means of a new hand chain connection
link.
