<p>A tong assembly (100) and a method for manipulating a tubular connection are disclosed. A centre member (208) is slidable relative to a body (202). A pair of clamping arms (210) are rotatably connected to said body (202). The clamping arms (210) are connected to said centre member (208) such that as said centre member (208) slides relative to said body (202), said clamping arms (210) rotate relative to said body (202). The assembly (100) also comprises a plurality of die assemblies (216A,216B,216C), wherein at least one die assembly (216A,216B,216C) is mounted to each clamping arm (210) and at least one die assembly (216C) is mounted to said centre member (208). <IMAGE></p> |
