Applications

A torque multiplier is a device that increases the torque that can be applied by an operator. Because the power output can not exceed the power input, the number of output revolutions will be lower than the number of input revolutions

(Torque x rpm = Power)

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 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.
