COMPARE THE DIFFERENCE of FORWARD TRAVEL

This drawing demonstrates the differences of forward travel in direct relation to vertical lift between the TrailerSaver Air Suspension Trailer Hitch Level Beam design, and the Angle Beam design on the right.

Notice the locations of the pivot points on the two models.

TrailerSaver Model TSLB (Design known as Level Beam)	Model “AB” ( Design known as Angular Beam)

You will notice by the arc of each hitch, that the TrailerSaver trailer hitch moves forward only 1/8" at its full lift of 4". On the Model AB design you will see by the arc that it has traveled forward. When this happens, the trailer is pulled forward on the up lift and then pushed backward on the down travel. This causes a surging action in the tow vehicle, and also puts added stress on the kingpin and pin box of the trailer. There are four of our competitors with this design.

Another important issue is where the head is located in relation to the air bags and the hinge. If the head is placed closer to the hinge, this accentuates the surging motion, if they have the same amount of travel. The competitors with the head placed close to the hinge cannot get the range of motion that you can get with the head placed far away. There is also the question of performance if the head is basically sitting on the hinge and not the air bags.
