Description: Torque multiplier is a heavy-duty tool used to increase the torque produced by torque wrenches. These are developed and designed to meet space restrictions in torque wrench applications. Torque multipliers are suggested for either tightening of high tensile bolts or loosening rusty and frozen nut bolts. Tulex torque multipliers are machined to high precision. The gear units are designed for multiplication of input torque. Multipliers are recommended for use where very high torque (over 100 kg.m) is required to minimise input effort. The use of torque multipliers reduces the manpower required as well as operator fatigue. The multiplier has a gear mechanism by which the torque applied on the input side is multiplied in a particular ratio. Tulex multipliers are available in multiplication factors of 5:1 and 25:1. Torque multiplier covers torque requirements from 100 kg.m to 925 kg.m (750 lb.ft to 7000 lb.ft). These are used to achieve an exactly calculated output torque keeping the fluctuation of efficiency small over a long period. It is extensively used in large petrochemicals and refineries.
