Just a comment on your unfortunate "accident".The failure on your lift is not that uncommon.The Perfectpark lift is made by Gemini auto lifts of Fort Worth,Texas.They also make Superior Lift and the Garagemaster 7000.I have personally seen two failures of this type and had direct contact with another person who had the same failure in So. Cal..The pulley bolts back off and disconnect or just plain break.I have sold both of these lifts at car shows and have made attempts to contact the customers I have sold to and have them check the bolts,retorque as necessary and request replacement bolts of better quality.I had a sample bolt looked at by a hardware professional outlet and was assured that it is only grade 2 offshore manufactured hardware.I have been in the automotive business since 1969,ASE certified and factory Ford trained.Since 1987 I have been in the automotive equipment sales and service and I am Still involved in that business,I am a factory Rep for various lines of equipment,Lifts included,but I will not mention any names to avoid any questionable sales technique.Be aware of this.Lifts unlimited and Superior Lifts are identical in manufacturing except for the columns.The pulley bolts and lock mechanismn are identical.That being said I have seen the same failures on both lifts.Lifts unlimited and Superior both have prior knowledge of this problem and still have not advised there customers of such.That is why I put accident in quotations.Accidents are not accidents if they are priorly preventable.My advise to owners of these lifts are to not use them until the pulley bolts have been inspected and replaced and the lock linkages have been replaced with heavier rods to insure complete lock release at all four corners.I would also contact your state industrial safety board and request inspection and certification of these lifts.I am informing my customers who bought these lifts to do the same.If you buy a lift,buy it from a professional who knows lifts,can answer all your questions and refrains from using negative sales technique.When they tell you to buy from them because it is cheaper or They tell you you don't have to pay the sales tax,that is negative sales technique.You need to hear why their lift is good not why others are bad.You can pay for quality or pay for crap.Quality lifts always have the same price all the time.No so called"show specials".Be a smart consumer.Investigate and compare the product and the company selling it.Ask how their ontime delivery record is and check with the BBB for any outstanding or unresolved complaints.The only thing worse than you being hurt in a lift accident is your loved ones being hurt.Lifts are a commercial product used by professionals on a daily basis.When you bring one of these into the residential enviroment,look for problems not associated with a commercial shop.A lift is not a toy and should be installed by a professional and maintained by such.They require training and your complete attention at all times,and should not be operated when children are present.In ending I emplore you to shop,compare and be aware.
Yours Truly,Liftman
