Lightweight Hydraulic Square Drive Torque Wrench Of Elongator Bolt Preloader

A hydraulic torque wrench is a power tool designed to exert torque on a fastener to achieve proper

tightening or loosening of a connection through the use of hydraulics. A torque wrench is applied to the

nut either directly or in conjunction with an impact socket. Hydraulic torque wrenches apply a

predetermined, controlled amount of torque to a properly lubricated fastener.

The main characteristics of a hydraulic torque wrench which set it apart from other powered wrenches of

similar function are that

(1) it must generate torque using only hydraulic means

(2) it must be self ratcheting

(3) it must include an accurate method of determining the amount of torque applied.

Actual Process Picture

A hydraulic torque wrench is significantly quieter, lighter weight and more accurate than pneumatic impact

wrenches capable of similar torque output, making it an appealing alternative for many users to the very

loud and cumbersome impact wrenches or torque multipliers which were formerly the only viable option for

working with very large nuts and bolts until the hydraulic torque wrench was introduced.
