STABIL-TRAK™
DESCRIPTION
Patented rear axle lock or Stabil-TRAK™
system works
to stabilize vehicle under various conditions. Appropriate
Operation and Safety Manual contains basic
Stabil-TRAK™
information; a copy of Operation and
Safety Manual should always be available in the storage
compartment located in the cab
.
The operator’s instrument cluster Stabil-TRAK™
light (1)
will be ON when the Stabil-TRAK™
system is in the
LOCKED mode.
The stabilizing system operates via an interface between:
• Boom proximity switch (2),
• Park brake switch,
• Service brake switch,
• Gear selector in (N) NEUTRAL,
• Hydraulic circuits,
• Electrical circuits and
• Five solenoid-operated valves on
Stabil-TRAK™
manifold (3)
Frame level cylinder (4) is also involved in
Stabil-TRAK™
system, but only passively, as
hydraulic oil travels between frame level cylinder
and Stabil-TRAK™
manifold to accommodate
Stabil-TRAK™
system operation.
The Stabil-TRAK™
lock system will be activated when
the boom angle is greater than 40° and one or more of
the following functions are activated:
• Engaging the Parking Brake Switch
• Placing the Travel Select Lever in (N) NEUTRAL
• Depressing and holding the Service Brake
• Model 10054 Only: Lowering both outriggers
onto solid terrain, and extending the boom
beyond a point between the “E” and “F” boom
extend letters (approximately 40ft [12 m])
With the boom lowered to an angle of less than 40°, the
rear axle lock system is not active and none of these
functions will affect the Stabil-TRAK™
system.
