手动扭力扳手一般为10000NM，太大了就很长，很难操作。 气动可以达到100000NM，电动一般为3500NM。如果是一般的扳手，需要检测扭力的仪器来检测（是破坏性测试，注意安全），如果是扭力扳手，上面有注明（或说明书上标明）了能承受的力值（超过了会破坏扭力扳手）.国外的目前我看大20000Nm, 再大就需要要用扭矩倍增器了.
The manual torque wrench is generally 10000NM, which is too long and difficult to operate. It can reach 100000NM for pneumatic operation and 3500NM for electric operation. If it is an ordinary wrench, it needs an instrument to detect the torque (destructive test, pay attention to safety). If it is a torque wrench, there is a note on it (or on the instruction manual) that the force it can withstａnd (beyond which the torque wrench will be damaged) At present, I think it is 20000 Nm higher in foreign countries. If it is larger, it needs a torque multiplier
加长套筒扭剪型电动扳手适用于M16-24的扭剪螺栓，不同于正常套筒的扭剪型扳手的是，加长套筒更适用于空间距离受限制的区域，如空间距离狭小，扳手或套筒放不进去的区域可以用加长套筒的扭剪扳手进行施工。
The lengthened socket torsional shear type electric wrench is applicable to M16-24 torsional shear bolts. Unlike the normal socket torsional shear type wrench, the lengthened socket is more applicable to areas with limited space distance, such as areas with narrow space distance where the wrench or socket cannot be put in can be constructed with the lengthened socket torsional shear wrench.
