This rugged tubular steel storage rack holds up to four GoCart auto carts. Simple pedestal mounting loads and unloads in seconds. Four swivel casters allow you to roll to the work area or out of the way for storage. Each dolly holds up to 1,500 lbs., so a full set lifts a 6,000-lb. vehicle with ease. Perfect for low-profile sports cars, as well as higher-clearance trucks and SUVs. Confidently and safely move vehicles around your garage. One or two operators can easily roll a vehicle wherever you need it. When you're finished moving those vehicles, you'll have all four dollies back on the rack in just a couple of minutes.The storage rack is the perfect complement to your GoCart dolly set. Operation procedures could not be simpler. Just extend the telescoping GoCart to its maximum width, then roll the GoCart over to the vehicle, so the aluminum rollers "hug" the tire. Twist close the valve and repeatedly step on the foot pump. The GoCart rollers will quickly engage the tire and prop up that quarter of the vehicle. Once you have reached the desired height, secure the pump mechanism into place and insert the connected pin into one of the elevation locks. Do this for each desired wheel. Since each dolly has two locking mechanisms, you and your vehicle are guaranteed safe passage anywhere you go.Once the vehicle is lowered, roll the dolly away from the wheel, lift it and set it in the rack. Durable, non-marring urethane casters ensure the storage rack is safe and easy to use.
