Abstract

A device for use with fork-lift trucks or the like to provide tipping and side shift facilities for ancillary apparatus attached to the truck. The device includes first and second frames and a sub-frame with two operatively connected fluid-powered rams. There is one mounting point for an ancillary on the sub-frame and an alternative mounting point for an ancillary on the second frame, whereby an ancillary so mounted may be tipped and/or side shifted according to which ram is operated.

Claims

1. A device for use with a vehicle of the kind comprising a mast and a carriage guided on the mast, said device comprising a main frame adapted for attachment to said carriage, said main frame comprising at least one main frame plate at each lateral side of the main frame, a sub-frame pivotally mounted on said main frame plates, at least one fluid-powered first ram connected between said main frame and the sub-frame for controlling tipping of said sub-frame, a pair of shafts extending across said sub-frame, a further frame mounted on and slidably guided by said shafts, and a further fluid-powered ram coupled between the further frame and said sub-frame for controllably side shifting the further frame, said device providing one mounting point for an ancillary apparatus on said sub-frame, and an alternative mounting point for an ancillary apparatus on said further frame, whereby an ancillary apparatus so mounted may be tipped and/or side shifted according to which ram is fluid-powered, wherein said main frame comprises a pair of parallel plates at each lateral side of the main frame, and the sub-frame comprises pairs of parallel plates each of which sub-frame pairs is located between one of the pairs of plates of the main frame.

2. A device as claimed in claim 1, wherein said sub-frame plates are interconnected by said shafts.

3. A device as claimed in claim 1 wherein a first tipping ram is located between each pair of sub-frame plates, and each first ram has its upper end pivoted to the corresponding main frame plates and its lower end pivoted to the corresponding sub-frame plates.

4. A device as claimed in claim 1 wherein the further frame comprises attachment points for connection of an ancillary apparatus.

5. A device as claimed in claim 1 wherein each said pair of sub-frame plates provides at least one attachment point for an ancillary apparatus, therebetween.
