Abstract:
A trolley for rail tracks (3) that are branched by means of switch points, characterized in that the trolley has moveable hooks, and the switch points are designed as passive switches without any moveable parts, where the hooks can engage a guide rail (12) of a passive switch in accordance with the desired travel direction,wherein the rail tracks (3) are suspended from a ceiling structure (23) and have an essentially closed hollow profile with a longitudinal slot (5) on its underside in order to protect against mechanical damage and contamination as well as environmental influences, and the inside of the hollow profile (22) has at least one drive wheel (9) for the electric suspended trolley EHB (21), which is connected to at least one holding device (24) for cargo to be transported which penetrates into the longitudinal slot (5), characterized in that, at least in the area of a branched section (2) on both sides of the longitudinal slot (5), the hollow profile (22) has a corresponding guide rail (12) parallel to the longitudinal slot, which can be engaged by ends (15, 16) of a single rocker (13) on the electric suspended trolley (EHB),wherein the holding device (24) has a support bearing (25), which fits a channel formed in the hollow profile (22),wherein at least in the area of the branched sections (2), the hollow profile (22) has inductive power transfer heads (20) which are assigned to the ends (15, 16) of the rocker (13),wherein free ends (15, 16) of the rocker (13) are equipped with guide wheels, andwherein the inductive power transfer heads (20) can be controlled by an intelligent logic which is integrated in the trolley and is able to compute an optimum trajectory.
