This electric servo motor torque wrench that integrates motor drive and control was independently developed and manufactured by SMG. It is used for bolting in a variety of industrial and mining applications.

Thanks to the design of advanced gear box and precise digital the torque output accuracy can be ±2%. The torque and angle can be freely adjusted within the torque range and reverse calibration can be performed. This tool automatically releases the reaction arm. The noise level is as low as 60 decibels. What’s more it has the function of data recording and collection.

Multi-stage planetary reducers made of ultra-high strength (2140MPA) steel are used in our tools making small size and light weight. This tool is applied for the industries of oil natural gas metallurgy petrochemical aviation military railway electric power high-end assembly and others.
