Claims
- 1. A device for the transport of rolled materials having a hollow core, said device comprising:
- a moveable support;
- at least one rigid vertical support member mounted on the moveable support;
- at least one horizontal member mounted to the at least one vertical support member to selectively move thereon in a vertical dimension;
- lifting means for selectively causing the horizontal member to raise and lower;
- an elongate, selectively expandable mandrel mounted at one end to the at least one horizontal member to selectively pivot vertically, to selectively move linearly in a lateral direction with respect to the at least one vertical support member, and to selectively frictionally couple to the core of rolled material by radial expansion therein and to release the core by contracting therein;
- means for selectively moving the mandrel linearly in a lateral direction with respect to the at least one vertical support member;
- means for causing the mandrel to selectively expand or contract radially; and
- means for causing the mandrel to selectively pivot in the vertical dimension.
- 2. A transport device as in claim 1 wherein the lifting means comprises hydraulic cylinder means.
- 3. A transport device as in claim 1 wherein the elongate expandable mandrel is cylindrical.
- 4. A transport device as in claim 1 wherein the means for causing the mandrel to selectively pivot is a hydraulic cylinder having first and second ends, the first end coupled to the at least one horizontal member and the second end coupled to the expandable mandrel.
- 5. A transport device as in claim 1 wherein the mandrel selectively pivots in an arc ranging from substantially vertical to substantially horizontal.
- 6. A manipulation and transport device for rolled materials having a hollow roll core, said manipulation and transport device comprising:
- a moveable base;
- one or more vertical support members mounted on the base to extend upwardly therefrom;
- a horizontal support means connected to the one or more vertical support members comprising a primary support member movably attached to the vertical support members so as to enable vertical movement of the primary support member, a secondary support member slidably mounted to the primary support member to selectively move thereon in a linear, horizontal direction either when loaded with rolled materials or when not loaded, and at least one guide disposed between the primary and secondary support members to enable linear, horizontal movement of the secondary support member relative to the primary support member;
- an elongate mandrel for the insertion into the core of rolled materials, mounted at one end to the secondary support member to pivot vertically, and such that movement of the secondary support member relative to the primary support member causes linear lateral movement of the mandrel relative to the one or more vertical support members;
- means for releasably securing the mandrel in the roll core into which it has been inserted;
- means for causing the mandrel to selectively pivot vertically; and
- means for causing the horizontal support means to selectively move upwardly or downwardly.
- 7. A manipulation and transport device as in claim 6 wherein one or more wheels are mounted to the base and the one or more vertical support members.
- 8. A manipulation and transport device as in claim 6 wherein said means for causing the horizontal support means to move selectively upwardly or downwardly comprises a hydraulic cylinder having first and second ends, the first end coupled to the base and the second end coupled to the horizontal support means.
- 9. A manipulation and transport device as in claim 6 wherein the means for causing the horizontal support means to move selectively upwardly or downwardly comprises a hydraulic cylinder means.
- 10. A manipulation and transport device as in claim 9 further comprising hydraulic pressure means including a pump, a reservoir, and an electric motor, wherein the hydraulic pressure means is mounted on the transport device.
- 11. A manipulation and transport device as in claim 6 wherein said mandrel pivoting means comprises a hydraulic cylinder having first and second ends, the first end of said cylinder coupled to the horizontal support means and the second end coupled to the mandrel.
- 12. A manipulation and transport device as in claim 6 wherein said securing means comprises expandable jaws extending radially from the mandrel.
- 13. A manipulation and transport device as in claim 6 wherein said horizontal support means further comprises articulation means which includes a hydraulic cylinder having first and second ends, the first end mounted to the primary support member and the second end mounted to the secondary support member.
- 14. A manipulation and transport device as in claim 6 wherein said at least one guide comprises bearings and guides mounted between the primary and secondary support members, the guides extending in a horizontal direction and the bearings disposed to travel on the guides.
- 15. A manipulation and transport device as in claim 6 wherein the one or more vertical support members form opposing channels, and further comprising bearings mounted on the horizontal support means to travel in the channels.
- 16. A manipulation and transport device as in claim 6 wherein the one or more vertical support members comprise two substantially parallel beams and at least one elongate-brace extending between and mounted to the beams.
- 17. A manipulation and transport device as in claim 6 wherein the base is U-shaped, having legs and a connecting member, the one or more vertical support members mounted on the connecting member, and the legs of the U mounted to the base to straddle a shipping pallet.
