Standard Series
Norbar '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 other brands. For example, the velocity ratio may be 29.8:1 to give a torque multiplication of 25:1 ±4%.
|
|
|
|
True torque multiplication guaranteed better than ±4%.
|
|
|
Torque outputs up to 47,500Nm.
|
|
|
High ratios allow the use of of a small torque wrench, multipliers can be used where access is limited.
|
|
|
All models over 25:1 are available with an Anti Wind-Up Ratchet (AWUR).
|
|
|
AWUR contains the 'wind up' developed in all high ratio multipliers allowing for easy and safe operation.
|
|
|
AWUR locks the multiplier onto the bolt once torque is applied. Handtorques can then be used upside down and will support their own weight.

Highwayman Multiplier
The 'Highwayman' torque multiplier has been designed for use where it is necessary to provide higher torques than would otherwise be possible due to limitations of space or operators strength.
Input to the multiplier is via a ratchet torque wrench set to one fifth of the desired output torque.
|
|
|
|
|
5:1 torque multiplication, accuracy guaranteed better than ±4%.
|
|
|
Supplied with two reaction bar styles for maximum versatility.
|
|
|
Robust construction means minimal maintenance and long life.
|
|
|
Supplied in a carrying case, the Highwayman is ideal for inclusion in the heavy vehicle tool kit.
|
|
|
1300Nm version has a spare 3/4" output square included in the kit.
