A lightweight portable trailer innovation uses rear wheel rotation to elevate and lower a platform. As the car drives onto the ramp, its front wheels surpass rollers due to insufficient lift force. Upon reaching the rollers, the vehicle's weight balances evenly around a central pivot. Only the mass of rollers and gear system must be overcome. The wheel motion is transferred through rollers and gears to the sprocket which climbs the chain, lifting the platform horizontally. To exit, the process is reversed.
