What is a Torque Multipliers?
It is a simple gear box, works on the principle of ‘Epicyclic Gearing’. The given load at the input gets torque multipliers as per the multiplication factor & transmitted at the output, there by with a minimum efforts you achieve greater load.

How They Work
Hand Torque Multipliers incorporate an ‘Epicyclic’ or ‘Planetary’ gear train having one or more stages. Each stage of gearing increases the torque multipliers applied by a factor of 5, allowing to offer torque multipliers in ratios of 5:1, 25:1 and 125:1. In the planetary gear system, torque multipliers is applied to the input gear or ‘Sun’ gear. Three or four planet gears whose teeth are engaged with the sun gear and therefore rotate. The outside casing of the torque multipliers, or ‘Annulus’ is also engaged with the planet gear teeth, and would normally rotate in the opposite direction to the sun gear. A reaction arm prevents the annulus from rotating, and this causes the planet gears to orbit around the sun. The planet gears are held between input & output plate which also holds the output square drive. Therefore as the planetary gears orbit around the sun gear, output plate the and so the square drive turns. Without the reaction arm to keep the annulus stationary, the output square will  not apply torque multipliers.

Why use a Torque Multipliers?
Safety - Use of long levers can be dangerous. Torque Multipliers mean a reduction in the lever length or operator effort by a factor of 5, 25 or 125.
Space Limitation - The use of a long lever may be impossible due to restricted space.
Accuracy - Torque Multipliers 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.

Anti Wind-Up Ratchet (AWUR):
With any high ratio gearbox (25:1 or more) a certain amount of wind-up (spring) has to be taken up before any useful tightening work is applied to the nut.

Each time the input device is released, the wind-up will rotate it back against the direction of operation.

The Anti Wind-Up Ratchet retains all of the wind-up forces as they are created, with the following benefits:

  1. The torque multipliers input device can not fly backwards against the direction of operation if it is suddenly released.

  2. Without an Anti Wind-Up Ratchet, it will often be necessary to continue to make 360 sweeps with the torque multipliers input device otherwise the torque multipliers will ‘unwind’. However, obstructions will often make this impossible.

  3. With an Anti Wind-Up Ratchet fitted, the torque multipliers becomes locked onto The nut because the reaction plate is held hard against the reaction point. This means that even used upside down, the torque multipliers will support it’s own weight.

Safety Note: Additional support is recommended as failure in the bolt, socket or torque multipliers will release the wind-up forces and cause the torque multipliers to drop.
