Is there a suitable alternative to a pneumatic wrench in terms of quieter and reduced vibration?
We currently use them for tightening vehicle wheel nuts and the noise is uncontrollable.
Are there any suitable alternatives???

A manual wheel brace such as those found in cars perhaps, with the final tightening being completed by torque wrench ?

In an ideal world then yes a manual wrench would be an option.
But the manual handling aspect is a nightmare and do you know how many nuts there are on commercial wheel let alone a whole trailer.
Thanks for the comments though

There are battery powered guns on the market we use them on heavy assembly bench work. No idea what torque setting they will go to. Just arrived home, If you get no joy I can bend the ears of our engineers tomorrow, as to what where and by how much ..

When in the automotive industry we had noise reducers fitted on all our air powered tools, and the air pressure as low as we could go without affecting the process, unfortunately the very nature of the operation means there will be vibration from tighteneing the wheel nuts to the specified torque. You could supply anti vibration gloves, however I do not know if they work, having not used them myself.
Sorry not musch help

*Nods.. No problems. I wasn't trying to make a joke or sarcastic comment, we have the same problem at our car dealerships. Pneumatic air tools.. can't hear with them can't work without them.

They are all subject to noise tests.
Maybe you haven't done them ?
There are suppression covers available for all modern air tools, and most new ones are also tested for vibration. Come to think about it....there have been silencers available for them for over 15 years...
The changes to the Noise Regulations in 2006 are:
The first action level of 85 dB changes to 80 dB(A).
The second action level of 90 dB(A) changes to 85dB(A).
The third action level of 200 Pascal changes to 140 Pascal

I do a lot of work in the automotive industry where pneumatic wrenches are the most common tool. A shift worker with a cycle time of 60 seconds will be screwing up maybe 1000 nuts per day. (7 hours, 420 minutes, two-three nuts per minute) Noise levels are well under the 85 dbA and vibration is minimal. (you can talk with them at a normal voice level) They are taught how to minimise the "torquing" effect (put a little more pressure on the right hand as the nut screws up) and seem to have no significant problems.
This from discussions with site medical

Thanks guys.
I am aware of the noise action levels its just that ive yet to undertake the actual noise survey as this is being done next week.
I was just mainly looking at solutions before I get to site. I will try Merv's recommendation and see.
Thanks again
