    摘要： Apparatus for safely lifting a roll of material having a horizontal eye is disclosed. The apparatus consists of a tong having horizontally relatively movable lifting legs which each include lifting decks to engage the roll's eye. Sliding members are provided to yieldingly address the roll ends and to move horizontally and vertically during closing of the lifting leg under the control of a dampening means. Additionally, the sliding members are maintained stationary with the roll during movement of the tong to engage the eye with the lifting decks to avoid scraping of the roll ends. A spring means is provided to return the sliding member to its rest position following the release of the displaced rolls.

    摘要： A motorized lever-action vertical axis coil grab manipulated in suspended disposition from an overhead crane by a single operator from a remote control location for clampably engaging for lifting and displacement from one location to another upright standing wrapped metal material coils of various size and dimension, with initial grab engagement of any particular coil to be moved by a motor-driven compressive clamping of the coil overply wall thickness to remove therefrom any wrap slack sponginess preparatory to tong latch release of the grab lever-acting self-gripping force translating tong linkage assembly such that no extension of the tong linkage assembly thereof will be wasted in taking up coil wrap slack but rather be substantially translated as increasing clamp compression on the coil wall thickness in a gripping force transmission sufficient to lift the coil without the convoluted laminate wrap structure thereof slipping apart upon coil elevation for movement, wherein the grab hereof further embodies as a feature thereof a tong latch load sensing switch assembly automatically operable to cut crane hoist motor power in an event where the tong latch does not properly cycle and release the lever-acting tong linkage assembly to effect a self-gripping force translation upon grab elevation of the motor-driven compressively clamped coil.
