HANDTORQUE® MULTIPLIERS HANDTORQUE® COMPACT SERIES KITS Multiplier & Torque Wrench Kits For convenience, it is now possible to purchase a torque multiplier from the 'Compact Series' packaged with the appropriate torque wrench, up to 4,000 Nm. This allows the operator to arrive at the bolting application with everything needed in one robust carry case. Space has also been allowed in the carry case for accessories such as sockets. The torque multiplier is supplied with its own unique calibration certificate and the torque wrench is supplied with a Declaration of Conformance, allowing accurate...

HANDTORQUE® MULTIPLIERS HANDTORQUE® TORQUE MULTIPLIERS What is a Torque Multiplier? A torque multiplier is a device that increases the torque that can be applied by an operator. This is because the power output cannot exceed the power input, the number of output revolutions will be lower than the number of input revolutions (Torque x rpm = Power). How HandTorque® Torque Multipliers Work HandTorque® multipliers incorporate an ‘epicyclic’ or ‘planetary’ gear train having one or more stages. Each stage of gearing increases the torque applied, allowing Norbar to offer multipliers typically in...

HANDTORQUE® MULTIPLIERS HANDTORQUE® TORQUE MULTIPLIERS Why use a HandTorque® Multiplier? • Safety – use of long levers can be dangerous. Torque multipliers allow for a reduction in the lever length or operator effort • Space limitation – the use of a long lever may be impossible due to the available space • Accuracy – torque will be applied most accurately when it is applied smoothly and slowly. Torque multipliers enable this by removing much of the physical effort from the tightening task Advantages of the Norbar HandTorque® System Norbar gearboxes are built to an extremely high standard...

HANDTORQUE® MULTIPLIERS ANTI WIND-UP RATCHETS (AWUR) Norbar Anti Wind-Up Ratchets (AWUR) Most multipliers with ratios of 15:1 and over are fitted with an Anti Wind-Up Ratchet. The multiplier can be thought of as a spring which must be fully wound before any tightening/untightening work can be applied to the bolt. The AWUR ensures that the 'spring' stays wound and that any further torque input to the multiplier is applied directly to the bolt. Multiplier behaves like a very stiff 'spring' Torque Multiplier will achieve maximum torque only after the 'spring' has been taken up Reaction Force...
