Hydraulic torque wrench working principle

Source: | Updated: Aug 17, 2015

Hydraulic torque wrench is a hydraulic-driven, providing high torque output, professional bolt installation and 

removal of the bolt tightening tools for tightening and demolition, usually used on big bolts. Not only improve 

the work efficiency, reduce labor intensity, but also greatly enhance the quality of installation, and conducive to 

on-site security management.

Hydraulic torque wrench is widely used. During the construction, maintenance, repair, etc. marine engineering,

petrochemical, construction, electricity, mining, metallurgy and other industries, the hydraulic wrench bolts for 

large-size installation and removal is a very important tool. It is irreplaceable. Not only convenient, light 

weight, but also provide huge torque and very accurate. 

Torque accuracy ±3%. According to statistics, about 50 percent equipment problems caused by the bolt, many 

accidents happened because of this, so in equipment installation, maintenance and repair process, the bolt 

tightening and loosing torque value is very accurate, unable to make it by artificial. For large-sized bolts

hydraulic torque wrench is the best choice.

Hydraulic torque wrenches are composed of working head, hydraulic pump and high-pressure hose.Through

the hose, hydraulic pump transfer power to the working head, driving the working head to tighten or loosen. 

Hydraulic pump can be driven by electricity or by air.
