The guided member engages with the guide member to resist twisting moments acting on the carriage and enable the carriage to move smoothly along the mast. A clamping apparatus for use with the lift truck is engageable with the forks of the lift truck so that the weight of the clamping apparatus can be supported by the forks. A bracket mounted on the lift truck can be detachably connected to the clamping apparatus to prevent movement of the clamping apparatus in the fore-and-aft direction of the lift truck.

- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
