How does steerable trailers know what steering angle to turn?
All the rage in Europe and England, Ireland how do these platform trailers turn on a dime also box vans are having this option.
Some I have seen on UTUBE have hydraulics/electronics to change steering on one axle, some change angles on 2-all axles!
Some manufactures use "caster" type mechanical steering. A good idea for the Northeast cities like NYC & Boston.
Saves tremendous tire ware, no scrubbing! I like the remote control features!
Is this a good question?
