Service and inspections may only be carried out by a competent person.
The inspection must determine that all safety devices are present and fully operational and covers the condition of the hoist, lifting gear,
accessories and supporting constructions.
The service intervals and inspections noted are for normal working conditions. Adverse working conditions, e. g. heat or chemical
environments, can dictate shorter periods.
The Yale electric chain hoist CPV/F conform to FEM group 1Am/M4 in accordance with FEM 9.511. This results in a theoretical service
lifetime of 800 operating hours under full load.
This is equivalent to 10 years under normal operating conditions. After this period the hoist requires a general overhaul. Further
information is contained in BGV D6 resp. FEM 9.755.
Attention: Maintenance work requires subsequent function testing with nominal load.
Daily Checks
• Visually check the pendant control switch and all cable for damage.
• Function check of the brakes (incl. triggering the EMERGENCY STOP button)
• Function check of the limit switches
• Function check of the overload circuit breaker
• Electric chain hoists with trolley:
• Check that the trolley runway is free from obstructions
• Check that the end stops on the trolley runway are fitted and secure.
Regular Inspections, Service And Testing
According to the existing national/international accident prevention or safety specifications, lifting units must be checked
• At least once per year by a competent person
• According to the risk assessment of the operating company,
• Before the initial start-up,
• Before restart following a shutdown
• After basic alterations. The concerned use 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 by the trade association, 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, or 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, in accordance with BGV D6 Cranes.
Paint damage should be touched up in order to avoid corrosion. All joints and sliding surfaces should be slightly lubricated. In case of
heavy contamination, the unit must be cleaned.
ATTENTION! Power supply must be disconnected while inspecting the device, unless the type of the examination excludes
this.
Maintanance of the load chain
The load chains are case hardened chains having the dimensions 4 x 12.2 DAT, 5 x 15.1 DAT and 7.1 x 20.5 DAT.
The CPV/F electric chain hoist is specially designed for type of chain. For this reason only chains that have been approved by the
manufacturer may be used in these hoists.
Non-compliance with this specification will render the legal warranty or guarantee void of CMCO Industrial Products GmbH with
immediate effect.
Lubricating the load chain
The load chain must be lubricated before the first start-up and every month, however after 50 hours of operation at the latest. Under
some extreme conditions such as an increased dust effect or a particularly heavy-duty use, the intervals are to be shortened
appropriately.
The service life of the load chain can be increased through careful lubrication to 20-30 times compared with a chain that is not serviced.
• The chain must be cleaned before lubrication. Burning off is not permissible. Cleaning methods that do not deteriorate the chain
material are to be used (e.g. vapour degreasing, alkaline dip degreasing).
Cleaning methods that can cause hydrogen embrittlement, e.g. pickling or dipping in acid solutions, as well as surface treatments, which
can hide cracks or damages, are to be avoided.
• The chain must be lubricated in a tension-free condition so that a lubrication film can be formed at joints. This can happen e.g. through
dipping in oil.
Checking for wear
Load chains must be inspected for mechanical damage once every three months and after 200 operating hours at the latest. Particular
operating conditions may also dictate shorter inspection intervals.
Visual check: There should be no cracks, deformities, bends, etc. along the entire length of the chain.
Round-section steel chains must be replaced when the original nominal thickness "d" on the chain link with the worst wear has been
reduced by more than 10% or if the chain has elongated over one pitch "pn" by 5% or over 11 pitches (11 x pn) by 2%. Nominal values
and wear limits are shown in the following tables.
The load chain must be replaced if one of the limit values is exceeded.
