(B)Powerful argument:
theadvantage
of thehigh-force cylinders lies in the
sequenceof up to four cylinderswith
thesamepistondiameter andstroke.
Securely clamped
Integrateddirectly in theproductionpro-
cessof the carmanufacturer, linear con-
veyor technology transports theaxleona
workpiece carrier through themachine in
either a longitudinal or a transversedirec-
tion. A lifting frame that canbe lowered
directlyabove theaxleholdsall of the
Festocomponentsand the tools foradjust-
ing trackand camber. After theaxle is
clamped, counterholdersswivel under the
subframemountsof theaxle, and later
provide theattachment points for the car
body. ADNHhigh-force cylinderswitha
pistondiameter of 100mm clamp theaxle
at four positionsasaccuratelyas if itwere
screwedonto thevehicle. Theadvantage
of theADNHhigh-force cylinders is in the
series connectionof two, threeor four cy
linderswith thesamepistondiameter and
stroke. Thismeans that, compared toa
conventional cylinder, the force canbe

wheel hub.Theheightatwhichaslideunit

Next, theaxle ispulsedunder load to

moved to theK0position. This is the ideal
