What does sliding the trailer tandems change?
- A.It changes the trailer's cargo capacity
- B.It raises the trailer roof height
- C.It shifts how the trailer's weight is divided between the trailer axles and the tractor's drive axles (and changes off-tracking and bridge length)
- D.It has no effect on axle weights
Correct answer
C. It shifts how the trailer's weight is divided between the trailer axles and the tractor's drive axles (and changes off-tracking and bridge length)
Why
Moving the tandem support point redistributes the load between the two axle groups, which is how drivers bring both groups within their limits. It also changes how the trailer tracks in turns, which the driver has to remember.
