mental protection office or commercial regulato-
ry office has the obligation to disclose about dis-
posal points).
• All weld seams must have a visual inspection. Stop
the system and contact the manufacturer if there
are cracks or breaks in weld seams.
• Check the powder coating and improve if re-
quired.
Damage by external influences is to be treated
immediately after detection. If these points are
not treated, infiltration of deposits of all kinds can
cause wide-ranging and permanent damage.
These points are to be lightly sanded (120 grit),
cleaned and degreased. Afterwards, rework with
a suitable touch up paint (note the RAL No.).
• Check galvanized surfaces and touch up as nee-
ded. White rust is fostered by permanent humidi-
ty, poor ventilation.
Rust is brought out by mechanical damage,
wear, aggressive deposits (de­icing salt, leaking
operating fluids) cleaning that is not done or in-
complete.
The affected areas can be treated by using a
sanding cloth (A 280 grit). If required, the parts
are to be treated with a suitable, resistant mate-
rial (paint etc.).
• Check the protective hose and hydraulic hoses:
• Check the condition of the protective hose
around the hydraulic lines. These should be ex-
changed if there is damage. During this, check
hydraulic lines for any crushing points (from third
party influences, e.g rolling over it with a load).
Any affected lines must be exchanged. Other-
wise pressurized hoses must be exchange as re-
quired, however at latest after 6 years.
Hose lines are to be replaced:
- for damage to the outer coating up to the insert
(chafe marks, cuts, cracks)
- for brittleness of the outer coating (crack forma-
tion), deformation of the natural shape in the
depressurized and in pressurized states.
- if leaking
- for damage or deformation of the mounting fix-
ture
- if the mounting fixture has meandered
- if the lifetime has been exceeded
Repair of the hose line using the implemented
hose / mounting fixture is not permitted!
Extending the replacement intervals given in the
guideline is possible if the inspection for safe-work
condition is done in adjusted, shortened time
frames, if required and by competent personnel.
If ther is an extension of the replacement interval,
no situation may occur which could result in injury
of employees or other personnel.
• For systems with aluminium panelling, these must
be removed to clean the drive in rails of dirt.
• Check the torque of the fastening anchor.
• The condition and function of the load suspension

means are to be checked.
• Check the torque of the fastening screws. Also
see the assembly protocol.

• The system is fitted with no­maintenance DU sli-
ding bearings. Despite this, due to environmental
influences of various kinds (e.g. humidity, dust,
dirt) bearing zones may become noisy.
In this case, spray the affected areas with an acid
and resin free oil spray (no adhesive oil or biologi-
cally degradable oil). Noises normally occur after
the system has been raised and lowered several
times.
• Check the function of the CE STOP with warning
signal.
7.2.2 Maintenance every 2 years
Change the hydraulic oil according to manufactu-
rers instructions.
7.2.3 Maintenance every 6 years
• Exchange the protective and hydraulic hoses.
Excerpt from BGR 237
Specifications for the hydraulic hose lines:
• Normal specification:
6 years including 2 years storage time.
• Increased demands e.g. due to increased usage
times, e.g. multi-shift operation, short cycle times
and pressure impulses and large external and in-
ternal (due to medium) influences which signifi-
cantly reduce the lifetime of the hose lines:
2 year operation duration
