Abstract
A gravity powered garage door control opening and closing system that eliminates the conventional electric garage door opener and eliminates its two most common risks of failure, the first being a gear and/or bearing failure and the second being an electrical power failure. Other advantages include a reduction in electrical power needed and a reduction in cost over every other type of garage door opener. The present invention operates by transferring fluid between a counter weight and a storage tank under programmed control to control the movement and speed of the garage door as a function of its position in the door guides in which the door moves in.
