If you are looking for some serious lifts cantact Daniel Gilstrap @
www.dghpts.comHE is making Pneumatic lifts which make no noise, We have done several Auton and Inca lifts that seem to shake the whole hose due to the straight cut gears.
Nothing like a 5 million dollar home with a $20,000 plasma tv in the living room and have to listen to the Growling gears of a lift when you have your weatlthy friends over for a peaceful evening of dinner and drinks and decide to watch a movie
Our lift clients have complained several times about the gear noise and asked if we could reduce it....Not really
Daniels Lifts are not much more and give you peace and quiet
