The following figures and notices are extracts from DIN 20066.
• Any twisting of the hose is to be avoided (see fig. 49).

• Hydraulic hose lines should be installed so that there is no tensile load in any operating
condition, except by own weight; the same is true for compressions with short lengths
(see fig. 50).

• If possible, hose lines should be installed according to their natural position whereas
the smallest bending radii admissible must always be complied with (see fig. 51).
Wrong
a – bending radii too small
