Material selection of high-strength lightweight hydraulic wrench aerospace aluminum alloy material TITAL-919, driven by a drive shaft wrench ultrahigh pressure liquid pump output to achieve the given value or removing the bolts fastening purposes. Multi-angle rotating pipe joints, make unrestricted use of space. Due to the use of sophisticated ratchet, accuracy up to ± 3%, the maximum torque of up to 100000N · m. It can be widely used in petrochemical, boiler tubes, steel, electricity, and other rolling stock. Features: forming one power head, lightweight high-strength aerospace aluminum alloy material TITAL-919 manufacturing, improve strength and life; a power head with a variety of work of the first to use a wide range of work can be 360 ??° × 360 ° rotation tubing joints closest tubingless design work completely without the use of space limitations head all inclusive design, security best; ultra-light, ultra-thin, large torque, adapt "difficult" Space
