A combination screening apparatus and carrier. The screening apparatus has three hydraulic leg assemblies which are adapted to lift and lower the screening apparatus off and onto a carrier. The legs are positioned and operable that a carrier may be slid directly under the screening apparatus without interference with the legs. The carrier has pivotable holding elements which engage grasping elements fixedly attached to said screening apparatus. The shape and configuration of the holding elements and grasping elements are such that the screening apparatus is self-aligning on the carrier. The carrier may be left under the screening apparatus or removed during screening operations.

Why it's free to use
- Filed April 2, 1997 and granted July 8, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 2, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 2, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
