ABSTRACT:
A tong assembly for grasping of a cylindrical body such as an air-conditioner compressor. A pair of cross bars are pivotally joined together by a flexible chain to which a hand grip is fitted and the lower end of each cross bar pivotally mounted to an upper section of a vertical strut. An open jaw shaped to fit externally about a compressor cylinder is pivotally mounted to each strut below the cross-bar joint, and an L-shaped grip is fixed to the bottom section of the vertical strut, shaped to fit about the bottom corner of the gripped compressor cylinder, with the clamp and grip of each strut located to face the opposed strut. Crossed stabilizing bars are pinned to the cross bars and the vertical struts to apply a torque to the struts about the clamps, when gripped about a suspended cylinder to prevent the bottom ends of the struts from rotating apart from each other.
