The load hook and the top hook (or the trolley for YLITP/YLITG and YLLHP/YLLHG models) of
the unit must be in a vertical line above the load centre of gravity (S) when the load is lifted, in
order to avoid load sway during the lifting process.
The selection and calculation of the appropriate supporting structure are the responsibility of
the operating company.
The attachment point and its supporting structure must be designed for the maximum loads to
be expected (deadweight of the unit + load capacity).
The following applies for all units with integrated trolleys (model ranges YLITP/YLITG and
YLLHP/YLLHG):
The hoist is suitable for a wide range of beams as well as for various profiles (e.g. INP, IPE,
IPB, etc.) with a max. inclination of the beam flange which does not exceed 14°.
The runway and its supporting structure must be designed for the maximum loads to be
expected (deadweight of the unit + load capacity). The runway must only have a deflection of
max. 1/500 of the span.
The longitudinal gradient of the travel path surface may not exceed 0.3%.
The air gap between the wheel flange and the beam flange ("dimension A") must range
between 1.0 and 2.5 mm on either side of the trolley (depends on model) in order to avoid a
potential source of ignition.
Trolleys must only be used with fitted buffers in order to exclude any spark formation.
The operator must ensure that the hoist is suspended in a manner that makes it possible to
operate the unit without exposing himself or other personnel to danger by the unit itself, the
suspension or the load.
The operator may start moving the load only after it has been attached correctly and all
persons are clear of the danger zone.
Do not allow personnel to stay or pass under a suspended load.
A lifted or clamped load must not be left unattended or remain lifted or clamped for a longer
period of time.
The hoist may be used at ambient temperatures between –20° and +40°C. Consult the
manufacturer in the case of extreme working conditions.
ATTENTION: Before use at ambient temperatures of less than 0°C, check the brake for
freezing by lifting and lowering a small load 2 - 3 times.
Prior to operation of the hoist in special atmospheres (high humidity, salty, caustic, alkaline) or
handling hazardous goods (e.g. molten compounds, radioactive materials), consult the
manufacturer for advice.
Always transport the load in the horizontal direction slowly, carefully and close to the ground.
When the unit is not in use, position the suspension (e.g. bottom block, hook) above normal
head height, if possible.
For attaching a load, only approved and certified lifting tackle must be used.
Correct operation involves compliance with the operating instructions and in addition also
compliance with the maintenance instructions.
In case of functional defects or abnormal operating noise, stop using the hoist immediately.
