A truck lifts rows of stacked trays from a floor for transport to another location. The truck has a pair of generally parallel arms that may slide into engagement with opposite sides of the lowermost trays in the row of stacked trays. The arms can then be lifted to raise the row of trays off the floor for transportation purposes. The arms are dimensioned to extend between adjacent rows of stacked trays and are configured to lift only the row between the arms.

Why it's free to use
- Filed May 1, 1990 and granted December 8, 1992. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 1, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 1, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
