DEVICE FOR DRIVING MULTIPLE CABLES OF A TRANSPORTATION SYSTEM OPERATING IN SYNCHRONISM, AND METHOD FOR AUTOMATIC REGULATION OF THE SYNCHRONOUS DRIVE OF THESE CABLES

摘要

The invention relates to a continuous scrolling drive device in synchronism in the same direction of several parallel cables at least tractors of a transport installation comprising in operation at least one vehicle coupled in line to said cables at least tractors and comprising means 1 drive separate from each cable independently of the others, separate energy sources supplying each drive means 1 independently of the others, means for controlling the drive speed of at least one drive means 1, so that these different cable drive forces correspond to equal running speeds of the cables.
