Abstract
The invention relates to an electric overhead conveyer comprising a large number of carriages (8), which circulate on a running rail system (1). Each carriage (8) has an autonomous carriage control (11), whose memory stores (13) all the data for the rail network. The overhead conveyer can either be operated in individual circulation mode, in which each carriage (8) attempts to travel individually at the greatest permissible speed, or in group mode. In group mode, the carriages (8), which are to traverse a common section of the rail network (1) are combined into groups and exchange data concerning the locally permissible speeds that are respectively valid. All the carriages (8) in the group then travel at a speed that corresponds to the lowest permissible speed for all carriages (8) in the group.
