Lowering the load
Turn pawl rod lever to the lowering position "↓" and lock it.
Operate hand lever with a pumping action.
Brake jamming
lf a hoist, which is under load, is suddenly relieved of load pressure, e.g. by lifting off the load
or when pulling down walls, and lowering has not been initiated first, the brake will remain
locked. The brake will also lock if the load hook with the bottom block is pulled too tightly
against the housing.
Releasing the jammed brake
Turn pawl rod lever to the lowering position "↓" and operate hand lever with a vigorous stroke.
lf the brake is jammed on extremely tight, it can be released by striking the hand lever.

According to national and international accident prevention and safety regulations hoisting
equipment must be inspected:
• in accordance with the risk assessment of the operating company
• prior to initial operation
• before the unit is put into service again following a shut down
• 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.
The unit must be given a general overhaul after 10 years, at the latest.
In particular, check the dimensions of the load chain, the load hook and the top hook.
ATTENTION: After the replacement of components, a subsequent inspection by a
competent person is obligatory!
Inspection of the load chain (acc. to DIN 685-5)
Load chains must be inspected for mechanical damage at annular intervals, however after 50
operating hours, at the latest. Inspect the load chain for sufficient lubrication and check for
external defects, deformations, superficial cracks, wear and corrosion marks.
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 when the chain has
elongated over one pitch ´pn´ by 5% or over 11 pitches (11 x pn) by 3%.
