Operation Instructions

FLIPPER PLATE IN THE 
ENGAGED POSITION

13.  PosiLok

 Anti-Dock Walk (Optional 

Equipment)

The CBX69 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 may 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 25)

.

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 26)

. 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 27)

. Refer to the troubleshooting 

section of Installation and Operation

Failure to adequately raise flipper 
plates could result in trailer, suspension 
component, and cargo damage.
