Abstract
A rotating handler arm is mounted on an upright column, and has electrical components thereon, which require powering. The power is carried to the rotating arm by a multi conductor flat cable that is supported on a platform adjacent to the rotating arm in a coil. The cable clamped to the platform as well as to the rotating member. The coil is made of a sufficient number of individual coil sections so that the coil will tighten as the rotating arm rotates in a first direction, and loosen as the rotating arm rotates in a second direction to avoid the need for slip rings or other complex electrical transmission elements.
