A normal shipping container sits in a frame which is supported top and center at the ends. Each support is a pair of hydraulic pistons. During a turn, the outside pistons extend, shifting the cargo toward the inside of the turn, and tilting the container. If this isn’t enough to keep the cargo in
place, the frame may be connected so as to swing freely.

physics is sound, not so sure about application on road transporters... [ConsulFlaminicus, Jan 02 2005]

A bit complex maybe, but it's a sound concept. [+] |

The name of this idea reminded me of the famous Penn and Teller trick, in which Teller had the wheels of a truck go over him. The truck was actually weighted to one side; the wheels that run Teller over were hollow rubber. |

This would look nice - another way to
do it would be to make the truck
steering the consequence of tilting the
load (the truck would have to be fitted
with giant skateboard axles) rather than
the other way round. |

The concept of 'active roll' has been around for a while. The problems could be: 1) if the system fails, it could tilt the wrong way and cause the truck to turn over. 2) The power requirement would be substantial, as it is always acting against the prevailing forces. 3) AN experiment by GM (I think) in the 1960's had a car fitted with suspension which provided roll into a bend. The test driver reported that the car felt like it was on rails, right up to the moment when it barrel rolled off the test track! In short, it is difficult to make such a system stable without complex control. |
