Abstract

An apparatus for lifting, maneuvering, winding or unwinding reels comprising a pair of devices having an elongated retractable frame having a first end and a second end which are adjustable relative to one another; a first crossbar having two opposite ends, the first crossbar being mounted to a first end of the elongated retractable frame; a second crossbar having two opposite ends, the second crossbar being mounted to a second end of the elongated retractable frame; a first roller carrier mounted on the first crossbar; a second roller carrier mounted on the second crossbar, parallel to the first roller carrier, wherein the roller rotates axially about the roller carrier; and a means for adjusting the first and second end of the elongated retractable frame relative to one another so that the first and second ends of the elongated retractable frame are moved closer together and further apart.

First claim

What is claimed is:

1. An apparatus for lifting, maneuvering, winding or unwinding reels, wherein the reel comprises a centrally-disposed barrel having two opposite ends and a first circular flange and second circular flange attached to each of the opposite ends, said apparatus comprising a pair of devices, wherein each device comprises:
a) an elongated retractable frame having a first end and a second end which are adjustable relative to one another;
b) a first crossbar having two opposite ends, the first crossbar being mounted to a first end of the elongated retractable frame;
c) a second crossbar having two opposite ends, the second crossbar being mounted to a second end of the elongated retractable frame;
d) a first roller carrier mounted on the first crossbar, wherein the first roller carrier comprises a first roller which is adapted to engage a rim of the first circular flange of the reel, wherein the roller rotates axially about the roller carrier;
e) at least one first flange guard positioned on one or both axially opposite ends of the first roller, wherein the at least one first flange guard extends radially away from the first roller in an angled configuration;
f) a second roller carrier mounted on the second crossbar, parallel to the first roller carrier, wherein the second roller carrier comprises a second roller which is adapted to engage the rim of the first circular flange of the reel, wherein the roller rotates axially about the roller carrier;
g) at least one second flange guard positioned on one or both axially opposite ends of the second roller, wherein the at least one second flange guard extends radially away from the second roller in an angled configuration; and
h) a means for adjusting the first and second end of the elongated retractable frame relative to one another so that the first and second ends of the elongated retractable frame are moved closer together and further apart, thereby moving the first and second roller carriers closer together and apart, respectively.

2. The apparatus of claim 1 , wherein the at least one first flange guard and the at least one second flange guard do not extend around the full circumference of the roller.

3. The apparatus of claim 1 , wherein the roller comprises a substantially cylindrical central portion and tapered opposite edges such that the diameter of the roller gradually increases as the distance between the central portion of the roller and each opposite edge increases, wherein the cylindrical center of the roller is adapted to engage the rim of the reel flange.

4. The apparatus of claim 1 , wherein the elongated retractable frame comprises a male member and a female member in a telescoping configuration.

5. The apparatus of claim 1 , further comprising at least two wheels mounted on the underside of each of the first and second crossbars.

6. The apparatus of claim 1 , wherein the roller carrier comprises two flange guards on each roller.

7. The apparatus of claim 1 , wherein when the rim of the first flange is engaged with the first roller and the second roller and as the first and second roller are moved closer together via the adjusting means, the first flange is lifted.

8. The apparatus of claim 1 , wherein the adjusting means comprises an actuating piston.

9. The apparatus of claim 8 , wherein the actuating piston is mounted on the outside of the elongated retractable frame.

10. The apparatus of claim 9 , wherein the actuating piston is mounted within the elongated retractable frame.

11. The apparatus of claim 1 , wherein the at least one first flange guard and the at least one second flange guard are angled away from the roller.

12. The apparatus of claim 1 , wherein the first roller and the second roller are configured to rotate axially, and the at least one first flange guard and the at least one second flange guard are configured to be fixed in place without axial rotation.
