Hydraulic hoses
Hydraulic bolt connectors:
Follow the final assembly guidelines:
– Cutting ring bolt connectors on the hydraulic
ducts, see above. Progressive ring bolt connec-
tors on the hydraulic ducts, see above. Biconal
ring bolt connectors on the hydraulic ducts, see
above.
Hose routing:
Follow the relevant specifications concerning the five
following illustrations.
– Avoid twisting the hoses during installation.
A = incorrect installation
B = correct installation
– Install hoses so that neither tractive force loads
nor upsetting loads occur with short lengths in any
operating status.
C = Wrong installation
D = Correct installation
– Rule of thumb: When jiggling on the hose in the
middle between two brackets/connectors (e.g.
clamps), the entire play of the hose should be at
least 1 cm.

Warning!
Hoses laid in a straight line become shorter
due to the internal hydraulic pressure.
Fittings may be torn out.
– Always install hoses with a slight sag.
Even in static positions.
