ART454....What brand name do you have.. I have a "BackYardBuddy" built in Cleveland. My BYB also has the features you have. Had it about 10 years or more and no problems at all..Mind it only travels up/down about a dozen time a year and once the Mustang is parked on it in November it stays up until april. Great for converting a 2 car garage into a 3 car. I've used it to dowork on the RTV and it has been handy for oil changes and was the cats meow when I had to replace a drive shaft u-joint on the pickup.
