Abstract
The sheet coil handling device consists of a carrier suspended from a hook, a support element being pivoted about a horizontal axis on the carrier. Forks are movable relative to the suport element by actuators acting between the forks and support, the actuators being movable on a direction perpendicular to the plane of the plane of the forks. The carrier is pref. coupled to the hook by resilient suspension elements a safety switch being being controlled by relative displacement of the carrier and resilient suspension elements. The forks and actuators controls are disabled when a coil is in position.
