Standard HandTorque multipliers
Pullertop standard HandTorque multipliers employ multiple stages of epicyclic gearing to give a wide range of torque outputs and ratios to suit most applications. Ratios quoted are always the torque multiplication ratio, not the velocity ratio as given for some competitor’s products. For example, the velocity ratio may be 29.8:1 to give a torque multiplication of 25:1 ±4%.
Product Description
Product Lines: Torque Multipliers
- Electronic torque transducers can be fitted for precise torque monitoring.
- True torque multiplication guaranteed better than +/-4%.
- High ratios allow the use of a small torque wrench, multipliers can be used where access is limited.
- Anti Wind-Up Ratchet available on models of 25:1 ratio and above.
Think Safety
Manufacturer’s rating of load and stroke are maximum safe limits. Good practice encourages using only 80% of these ratings!
