Coil handler device
View Patent ↗A coil handler device is configured for grasping, lifting and transporting a coil of material that is coiled in such a manner as to have an outer periphery and an inner periphery and to define a longitudinal axis. The handler device includes a frame and a grasping and lifting assembly. The grasping and lifting assembly includes at least one clamping clement having first and second clamping surfaces for engaging and securing the coil along a radial line at the inner and outer peripheries of the coil. The clamping element includes a first clamp leg elongated in a direction along the radial line and a second clamp leg fixedly connected to the first clamp leg transverse to the first clamp leg at a first end. The second clamp leg has a second end operably connected to a lifting assembly for raising and lowering the coil when it is secured by the clamping element. The grasping and lifting assembly includes first and second clamp arms positioned along the first clamp leg for securing the coil at the inner and outer peripheries. The first clamp arm is spaced from the second clamp leg and the second clamp arm is intermediate the first clamp arm and the second clamp leg.

wherein the grasping and lifting assembly includes a central spacing element and wherein the at least one clamping element is operably connected to the central spacing element.
2. The coil handler device in accordance with claim 1 including three clamping elements connected to the central spacing element, the clamping elements being equally radially spaced from one another.
3. The coil handler device in accordance with claim 1 wherein the at least one clamping element is operably connected to the central spacing element by a link to permit movement of the clamping element relative to the spacing element.
4. The coil handler device in accordance with claim 1 wherein the second clamp arm is fixed on the first clamp leg and wherein the first clamp arm is moveable toward and away from the second clamp arm to permit positioning the clamping element over the coil and locking the clamping element onto the coil.
5. The coil handler device in accordance with claim 1 wherein the grasping and lifting assembly includes a cable operably connected to the at least one clamping element for raising and lower the clamping element.
6. The coil handler device in accordance with claim 5 including a crank operably connected to the cable.
7. The coil handler device in accordance with claim 1 wherein the frame includes a carriage for moving the handler device.
8. The coil handler device in accordance with claim 7 including a plurality of wheels mounted to the carriage.
9. The coil handler device in accordance with claim 1 wherein the frame includes a base having an open end and an open central region, and wherein the at least one clamping element is positioned vertically above and about centrally of the open central region.
10. The coil handler device in accordance with claim 9 wherein the frame includes a boom and wherein the at least one clamping element is supported from the boom over the open central region.
11. A coil handler device for grasping, lifting and transporting a coil of material, the material coiled in such a manner as to have an outer periphery and an inner periphery and defining a longitudinal axis, comprising:
a frame; and
a grasping and lifting assembly including three clamping elements each having first and second clamping surfaces for engaging and securing the coil along a radial line at the inner and outer peripheries of the coil, each clamping element further including a first clamp leg elongated in a direction along the radial line and a second clamp leg fixedly connected to the first clamp leg, the second clamp leg being transverse to the first clamp leg at a first end, the second clamp leg having a second end operably connected to a lifting assembly for raising and lowering a coil secured by the clamping elements, the grasping and lifting assembly including first and second clamp arm positioned along the first clamp leg for the coil at the inner and outer peripheries, the first clamp arm being spaced from the second clamp leg and the second clamp arm being intermediate the first clamp arm and the second clamp leg.
12. The coil handler device in accordance with claim 11 wherein the grasping and lifting assembly includes a central spacing element and wherein the clamping elements are operably connected to the central spacing element, equally radially spaced from one another, each of the clamping elements being operably connected to the central spacing element to permit movement of the clamping elements relative to the spacing element.
13. The coil handler device in accordance with claim 11 , wherein the second clamp arm is fixed on the first clamp leg and wherein the first clamp arm is moveable toward and away from the second clamp arm to permit positioning the clamping element over the coil and locking the clamping element onto the coil.
14. The coil handler device in accordance with claim 11 wherein the frame includes a carriage having wheels for moving the handler device.
15. The coll handler device in accordance with claim 11 wherein the frame includes a base having an open end and an open central region, and wherein the clamping elements are positioned vertically above and about centrally of the open central region.
16. The coil handler device in accordance with claim 11 wherein the grasping and lifting assembly includes a cable operably connected to the clamping elements for raising and lower the clamping elements.
17. The coil handler device in accordance with claim 16 including a crank operably connected to the cable.
