Overhead conveyor, especially electric overhead conveyor with monorail

摘要

The invention relates to a monorail system, in particular a monorail monorail system, with at least one trolley (1) movable on rails (5), with a drivable impeller (3) and with at least two spaced apart on the impeller (3) in the direction of travel (F) and spaced-apart friction wheels (15) which are guided on the chassis via a connecting element (16) and are braced against one another via a spring element (23) in such a way that in the area of an additional rail which is at least partially largely parallel and at a distance from the rail (5) (14) apply additional pressure to the friction wheels (15) which are in contact with the additional rail (14) in their operating position. In order to create a monorail whose driven undercarriage has improved traction properties with a simultaneously structurally simple construction and can therefore be used in particular on inclines and descents, it is proposed that the friction wheels (15), the connecting element (16) and the spring element (23 ) form a structural unit resting on the impeller (3), which is guided via a guide element on the chassis (1) in such a way that the structural unit can be moved around the impeller (3) from its operating position into a rest position, in the direction of travel (F) seen front friction wheel (15) can be moved into the space between the rail (5) and the additional rail (14), and from the rear friction wheel (15h) seen in the direction of travel (F) through the contact with the additional rail (14) is pivotable in the operating position.
