A lifting device is disclosed in which tong arms are coupled to parallel laminated horizontal spine members that slide in opposition to each other via input of force from the tong arms. The horizontal spine members are coupled to load-engaging feet to transfer the force of the tong members to a given load. The horizontal spine members include teeth or the like along a horizontal axis for engagement and indexing of the load-engaging feet.
