ABSTRACT:
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.
