Abstract
The mass (1) is suspended from free pulleys (2) connected to fixed pulleys (3) resting on a support (4). Its cable (5) is wound onto a toothed wheel (7) through a pinion (9). A chain (10) rides over sprockets (12, 13) and is attached to the mass. A generator is connected to a sprocket (13). The systems is fitted with a shock absorber (17) placed below the mass. The mass may be disconnected from the motor drive when it has been wound up to the top position.
