Inspection criteria for hydraulic
hoses
NOTE
The following inspection criteria must be ob-
served in the interest of your own safety and to
reduce environmental damages!
Replace hoses, if these fulfil at least one
criterion from the following list:
¾
Damage to the outer layer to the ply (e.g.
chafing, cuts, cracks).
¾
Embrittlement of the outer layer (formation of
cracks in the hose material).
¾
Deformations, which do not correspond with
the natural shape of the hose. Both in pres-
sureless and pressurized condition or in case
of bending (e.g. layer separation, formation of
blisters, squeezing, buckling).
¾
Leakages.
¾
Failure to comply with installation require-
ments.
¾
The max. utilization period of 6 years has
expired.
The date of manufacture on the hydraulic
hoses fitting plus 6 years is decisive. If the
fitting is marked with the manufacturing date
"2018", the utilization period ends in January
2024.
NOTE
Leaking hoses / pipes and connecting pieces
are frequently the result of:
¾
missing O-rings or seals
¾
damaged or poorly fitted O-rings
¾
brittle or deformed O-rings or seals
¾
foreign objects
¾
loose hose clamps
Assembly and disassembly of
hydraulic hoses
NOTE
Use only original spare hoses from HORSCH.
These spare hoses withstand the chemical,
mechanical and thermal loads.
¾
Generally use hose clamps made of stainless
steel when installing hoses.
When installing and disassembling hydraulic
hoses comply with the following notes.
Ensure cleanliness!
Hydraulic hoses must be installed so that the fol-
lowing is ensured under any operating condition:
•
no tensile loads, except by own dead weight
•
no buckling stress in case of short lengths
•
no falling below the permissible bending radii
•
avoiding external mechanical stresses on the
hydraulic hoses
•
no rubbing of hoses on components or against
each other through appropriate arrangement
and fastening
•
if necessary, protection through protective
sheathing
•
covering sharp-edged components
¾
Fasten hydraulic hoses at the intended fas-
tening points.
¾
Hose clamps are to be avoided at locations
where natural movements and changes of the
hose length may be interfered with.
¾
It is not permitted to cover hydraulic hoses
with paint!
