Abstract
A portable device is used to aid a semi-truck driver in the repositioning of a tandem axle assembly of a trailer. The portable device may be easily attached and removed from the trailer'"'"'s sub-frame during operation. The device will signal the driver visually when reaching the desired position during adjustment of the tandem axle assembly to a new location. The device may reduce time and increase safety for the driver during the tandem axle assembly repositioning operation. The device may be positioned at or near the desired tandem axle assembly position. A flap may pivotally hang in a position where a tire from the tandem axle assembly may deflect and pivot the flap when the tandem axle assembly reaches its desired position. A driver may see this flap deflection and know, with certainty, that they have achieved the desired tandem axle assembly position.
