1. The advanced safety protection system is adopted. When the safety valve is opened, the input high-pressure oil of the hydraulic system is automatically cut off, and the casing tongs stop running immediately, which effectively ensures the personal safety of the operator.
2. The split hinged bull gear transmission and multi-roller aligning support structure are adopted to greatly improve the strength and rigidity of the casing tong and facilitate the opening and closing of the power tong.
3. Precision casting is adopted for jaw tooth seat, with beautiful appearance, high strength, convenient disassembly and assembly, reliable clamping and easy back slope.
4. Magnet braking mode is adopted, which is easy to operate and easy to repair and replace.
