INTRODUCTION

The HandTorque multiplier is a precision tool that will multiply the input torque by the specified ratio.
®
The HandTorque multiplier is a planetary gear system. The outer case of the multiplier, known as the
®
annulus, will rotate in the opposite direction to the input torque unless a reaction arm is fitted to the annulus.
Without the reaction arm no torque is applied through the square drive. See section on torque reaction (Page
5) for more details.
HandTorque multipliers with a high ratio gearbox (25:1 or more) require a certain amount of windup
®
(backlash) to be taken up before any useful tightening work is applied to the nut. In this instance an Anti
Wind-Up Ratchet (AWUR) is fitted to retain all of the wind up forces. See section on AWUR (Page 10 – 11)
for more details.
