Anti-Dock Walk (Optional
Equipment)
The CBXA 40 suspension can be equipped with SAF ® PosiLok ™
which provides enhanced trailer stability during loading and
unloading operations. If the trailer air control system employs
a “spring brake priority” type arrangement, potential field
service issues could arise due to operational misuse, such as:

Moving a trailer before the air springs have been
properly inflated.

Use of yard hustler equipment.

Heavy load operations, such as paperhaul, with the slider
in the full forward position.

Engaging the emergency trailer brakes at a high rate of
speed (greater than 5 mph) to move the slider position.

Use of an auxiliary suspension dump valve with excessive flow.

Going in and out of ramped docks with slider all the
way forward.
SAF
®
PosiLok
™
system will properly support the trailer during
normal operations and is designed to bend or buckle when
subjected to overloading or other operational issues to
protect the trailer sub-frame.
The PosiLok
™
is engaged when the flipper
plates are in the down position.
1. Release air pressure from the trailer brake system or
disconnect the glad hand. This engages the parking
brakes and causes the PosiLok
™
actuator to engage,
which rotates the rod so the flipper plates swing down
into an engaged position
(Figure 26) .
The PosiLok
™
is disengaged when the flipper
plates are in the up position.
1. When the parking brakes are disengaged, the primary height
control valve (HCV) takes full function. When the system
has sufficient air pressure in the suspension air springs,
the actuator extends, rotating the rod so the flipper plates
swing up away from the load pads into a disengaged
position
(Figure 27) . The vehicle is now ready for movement.
IMPORTANT: DO NOT operate vehicle (put in motion) if
flipper plates are trapped in the down position
(Figure 28) . Refer to the troubleshooting
section of Installation and Operation Manual

Failure to adequately raise flipper
