A system for servicing a racing car or other car at a track, other race course, or similar destination employs an open platform for supporting the car by its tires in a horizontal position. The platform supports the car, and is itself supported by a crawler, in a carrier vehicle, for example a truck
A system for servicing a racing car or other car at a track, other race course, or similar destination employs an open platform for supporting the car by its tires in a horizontal position. The platform supports the car, and is itself supported by a crawler, in a carrier vehicle, for example a truck or trailer, when the carrier vehicle is transporting the car. The crawler and platform are also used to unload and load the car from and into the carrier vehicle. To unload the car at the destination, the crawler, with the platform and car on it, is driven out of the carrier vehicle and onto the ground. Next, the platform is elevated by extending its legs so that it rises off, is spaced from, and straddles the crawler. Then the crawler is driven out from under the platform. Then the platform is lowered to the ground, where it is used as a lift to elevate the car so that its undercarriage may be accessed. The platform may also be used to tune the chassis of the car. The chassis tuning may include manipulating the chassis to a static position which emulates an instantaneous position of the car on the race course. The carrier, platform, and car may be loaded back into the carrier vehicle by the reverse procedure.

1. A method of manipulating a stationary, four-wheeled racing car car in a static position which emulates an instantaneous position of the same systems of the same car when the car is being driven on a race course, and then observing or measuring the relative positions of at least some of components
1. A method of manipulating a stationary, four-wheeled racing car car in a static position which emulates an instantaneous position of the same systems of the same car when the car is being driven on a race course, and then observing or measuring the relative positions of at least some of components of the systems, which method comprises providing at the course a mobile, free-standing, generally rectangular, substantially rigid platform which is capable of supporting the car by tires on the wheels of the car in either an elevated, horizontal position or a lowered, horizontal position on the ground, which platform comprises a plurality of extendible legs for supporting the platform at varying distances from the ground, a first force-multiplying mechanism for extending and retracting the legs so as to move the platform to the elevated position and to the ground position, four second force-multiplying mechanisms for applying vertical forces to the frame of the racing car, at least one access opening permitting access to the undercarriage of the car through the platform when the platform is in an elevated, horizontal position, and four weight-sensing scales, providing sensors at the course, driving, on the course, the car equipped with the sensors, sensing selected positions or forces by the sensors during that driving, recording the sensed positions and forces as digital data varying as a function of time, using the digital data for one point in time to predetermine the static forces to be applied to the frame by the second force-multiplying mechanisms, rolling the car from the ground onto the platform in the ground position with a tire resting on each of the four the weight-sensing scales, extending the legs so as to raise the platform to an elevated position, with the legs bearing on the ground, connecting a second force-multiplying mechanism to the frame by a person reaching through at least one access opening, activating the second force-multiplying mechanism so as to apply predetermined, vertical, static forces to the frame, observing readings on the scales, and observing or measuring the relative positions of selected ones of said components. 2. The method according to claim 1 wherein the second force-multiplying mechanisms are capable of applying both upward and downward forces to the frame at the four spaced locations. 3. The method according to claim 1 wherein each of the four spaced locations on the frame is near a tire. 4. The method according to claim 1 whereby, based on the digital data, the manipulating replicates the instantaneous relative positions of the suspension, steering, and wheel systems of the car which actually occurred on the course at said one point in time. 5. The method according to claim 4 wherein the digital data includes shock absorber extension and steering angle.
