  • Patent number: 5979605
    Abstract: A service area is provided with a service area floor having a service pit sunken therein. A service lift is then provided within the service pit, and the service lift includes a service platform which is adjustable between a lowermost height to an uppermost height substantially equal to the height of the service area floor. Service personnel situated on the service platform within the service pit may thus actuate the service platform to various heights within the pit to allow comfortable servicing of the underside of a vehicle without the need to crouch or resort to the use of stepladders. The service platform can also be lifted to its uppermost height to effectively close the service pit, thereby enhancing the safety of the service area. The service lift most preferably uses air springs to effect the actuation of the service platform.
