Popular for Mining Caterpillar, Komatsu, Power Stations and on Pipe flanges in petrochemical. RAD pneumatic torque nut runners offer adjustable controlled torque. The RAD Pneumatic Torque wrench is ideal for screwing pullers & wheel nuts both tightening and loosening bolting. The RAD pneumatic nut runner torque tools are non Impacting and provide an adjustable torque setting. Common mining tools include the RAD 10gx RAD 14gx RAD 1800 RAD 2000 and RAD 3000

RAD Air Torque multipliers, are ideal for wheel nuts and general engineering. These Air torque guns can be set via a regulator with a final torque accuracy of + or - 5%.  RAD torque Multipliers should be used with Impact Sockets. TJ Tools carry a large range. RAD torque multipliers can be used for driving Bearing Pullers at content speeds and loads. Popular RAD torque tool applications include Track Presses or master link bolts on Dozer Tracks, wheels on Loaders and Dump Trucks. RAD Tools can be specifically set up with nose extensions to suit Cat & Komatsu truck wheels.

The RAD 50 tool offers from 1,500 to 5000 Ft lbs. This makes heavy Industrial bolt torqing easy. These nuts are 3" a/f and are torque to 4,500 Ft lbs. This tool has a 1-1/2" Square Drive and provides up to 7 RPM.This application is a coal fired steam boiler press.

Like any other high pressure joint, correct torque is critical, to ensure even load across the flange.The torque output is set using a supplied torque chart. This chart has PSI and torque readings. Simply set the torque required by adjusting the regulator before operation.

The RAD tools are the solution for this job. Liner bolts need the correct torque. Using rattle guns simply over, or under-tigtens bolts. The result is bolts failing.
RAD are High RPM torque tools. They offer torque accuracy to within 2% repeatability. By applying correct torque bolts stay tight. By not over-torquing, the bolts retain their integrity. Most Mills have hundreds of bolts. Re- liner shutdowns hold up production. Rad is the answer. 88 times less vibration 55% less db. fasteners reliable again. Less down time, Safe. Get the job done right the first time.See Video Liner Bolts RAD 50

Pnematic Nut Runners

ideal for torque wheels Nuts on Loaders and Dump Trucks. RAD Tools are specifically set up with nose extensions to reach in past the planetary hubs. They suit Caterpillar, Komatsu, Terrex Etc. RAD provide many solutions for Wheel Nut re-torques. Often access to wheel nuts is restricted by hubs or the depth of the rim. The RAD unit replaces the need to swing on Hand Torque Wrenches during torque up. It also replaces the use of Rattle Guns which offer no measurable consistent torque accuracy.

KOMATSU 930E-1,2,3,4 Dump Truck Wheels - Pneumatic Torque Tool
Rad offer a specialized tool for these wheels. Special Reaction Arms are used to achieve push points. The tool has been set up to torque wheels on a Komatsu 930e Dump Trucks. See Video this tool.

komatsuAdditional Reaction plates attaches to the tool to do the rear wheels as the the rims are deeper. This unit has a 1" Drive and does 3,200 Ft Lbs. As used by Otraco Tyers The RAD tool offers simple solutions for applying torque to wheel nuts. Part No for this tool is: 49001

Rimex Wheels may require a different tool depending on the Komatsu Model.

Many types of reaction arms to enhance the tools usability. Long arms are common for jobs that are unable to secure a reaction using the standard arm. Applications like Mill Liner bolts, Dozer Tracks, Bridges, Crushers are some of these.

Pneumatic torque tools use an Air / Lubro unit between the Tool and the air supply. These units provide 3 main functions. They have an adjustable air regulator which is used to set and control the final torque out.

The Lubricator supplies an automatic drip oil feed to the air motor. This ensures air motor longevity. The water trap helps trap water in the air.


How do Pneumatic Nut Runners work? Pneumatic torque guns use compressed air to spin a air motors. Before the air reaches the motor an inline regulator and Oiler are used. The regulator reduces the Air Flow and pressure to a measured amount. This is how the torque output is controlled. The tool will stall, when the correct torque is achieved. The air motor drives a gear box to produce a multiplier effect. The tools operate in forward and reverse. Planetary gear systems are used to produce low ratios. This system achieves a smooth torque accuracy of +/ - 5% or better. This gives the operator a known torque output. As the nut tightens the resistance slows the tool until it stalls. At this point the torque is achieved. The tool is calibrated by a transducer to produce a torque chart. Readings are used from this to set the tool. EG: Set the regulator to 45psi air in, to achieve 1,600 Ft Lbs at the tool.
