Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for handling cargo are disclosed which include a plurality of cargo carriers capable of being operated manually by human operators or remotely by a central controller. The carriers are operated in their manual mode to traverse paths near aircraft or other movable objects whose stopping positions cannot be accurately known until arrival. Once the carriers have been loaded and manually guided away from the movable object, they are driven onto a track from which point an automated controller takes over to guide the carriers to their destinations.

Why it's free to use
- Filed April 29, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 29, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 29, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
