OTR Mining Pneumatic Torque Wrench

A pneumatic torque wrench is an air-powered tool that uses compressed air to generate high torque output for tightening or loosening large fasteners. Designed for harsh environments, it offers intrinsic explosion-proof safety – critical in oil & gas, mining, or chemical plants where sparks from electric tools could ignite flammable atmospheres. While requiring an air compressor, it provides robust performance with lower maintenance and higher power-to-weight ratio than many electric alternatives.

Features

PTWE series pneumatic torque wrenches with extended long mouth reaction arms can easily solve the problem of sunken bolts with tight gaps
* To avoid outdoor accidents, the wheel hub bolt torque must be precisely controlled
* Compared with traditional impact torque wrenches that tighten nuts too tight or too loose, PTWE has the advantages of no impact, no vibration, and high precision
* Precision transmission devices can more easily and accurately solve nut tightening problems
* Equipped with extended force arms required for different working conditions
* Personalized customization, design
