Model TQH340-35Y tong is a Chinese version of Weatherford 16-25 tong. It’s a hydraulic motor-driven tong capable of running pipe or casing from 5.1/2 to 13.3/8 inches in diameter. Changing the rotary and jaws, the power tong can run pipe or casing from 13.3/8 to 16 inches in diameter. If change the jaws, the tong can run pipe or casing from 4 to 5.1/2 inches in diameter. With a 32 inch (813mm) handle, the tong can produce up to25,815lb·ft.(35KN·M) in low gear, forward or reverse operation. All the major consumable parts of this tong are interchangeable with the OEM Weatherford 16-25 tong.
