Lifting axle design types
Pulse-controlled: The valve has two solenoids that can be used, apart from
charging and venting, to effect a holding position to partially relieve the lifting axle.
Spring-returned: The lifting axle is lowered or lifted without intermediate positions.
If the voltage is switched off, the lifting axle is lowered.
Single-circuit or dual-circuit: With the dual-circuit valves the support bellows for
the lifting axles are connected separately (by side) with the other support bellows.
These valves are required for soft or split axles. Due to the stiffness of the axles
typical for trailers, the simpler single-circuit lifting axle systems are now prevalent.
Here the two support bellows of the lifting axle are directly connected to one an-
other.
Lifting axle control LA1
You have the following connection options for control of the 1st lifting axle or two
lifting axles controlled in parallel: A spring-returned lifting axle control valve
464 084 0.. 0 or a pulse-controlled lifting axle valve 463 084 100 0 or a pulse-
controlled ECAS solenoid valve block with lifting axle control 472 905 114 0.
Lifting axle control LA2
The following connecting methods are available for controlling the 2nd lifting axle:
A spring-returned lifting axle valve 463 084 0.. 0 or a pulse-controlled lifting axle
valve 463 084 100 0.
