LIFT AXLES
All truck lift axles (pushers and tag), are direct wire Electric-Only from the switch to the axle mounted solenoid. This is not
from the EoA Solenoid Bank. There are a total of four lift axle controls available; 3 pushers and 1 tag axle. These are con-
trolled with separate switches by default. The customer can order the following configurations; steerable, non-steerable,
with auto-reverse, and with park brake interlock. A lift axle comes with a control switch (single or separate), a gauge, and a
regulator valve.
