手動扭力扳手一般為10000NM，太大了就很長，很難操作。 氣動可以達到100000NM，電動一般為3500NM。如果是一般的扳手，需要檢測扭力的儀器來檢測（是破壞性測試，注意），如果是扭力扳手，上面有注明（或說明書上標明）了能承受的力值（超過了會破壞扭力扳手）.國外的目前我看大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
加長套筒扭剪型電動扳手適用于M16-24的扭剪螺栓，不同于正常套筒的扭剪型扳手的是，加長套筒更適用于空間距離受限制的區域，如空間距離狹小，扳手或套筒放不進去的區域可以用加長套筒的扭剪扳手進行施工。
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.
The above is a detailed introduction of the torsional shear electric wrench, and I hope it will be helpful to you. If you have any questions, please contact us. We will provide you with professional services http://m.bjqunyao.com
