As one might know, using manual torque wrenches to complete bolting jobs is tedious, inaccurate, time consuming, and unsafe. Hence, major industries like power, heavy manufacturers, oil and gas, and infrastructure use hydraulic, battery or pneumatic torque wrenches to achieve precision bolting. In this article, we will talk about some manual bolting methods practiced and draw a comparison between hydraulic, battery/ electrical pneumatic torque wrenches.
The most common reasons for heavy industrial applications to use battery, pneumatic or hydraulic tools is because of the high torque requirement to open old, corroded and rusty fasteners which is labour intensive and time consuming if done manually. Another reason to opt for these torque tools is that there is no operator fatigue involved.
