Transport system

A transport system for transporting objects, said transport system comprising a transport rail, which has at least a first running surface and a second running surface that are arranged disposed opposite one another, and at least one transport trolley comprising:

• a base body that is coupled or can be coupled to an object carrier for receiving at least one object to be transported,
• at least a first roller rotatably supported about a first axis of rotation and at least a second roller rotatably supported about a second axis of rotation, wherein the first and the second roller are arranged at the base body such that the first and the second axis of rotation are stationary relative to the base body and such that they cooperate with the first running surface,
• at least a third roller that is rotatably supported about a third axis of rotation and that is arranged at a pivot arm that is pivotably arranged at the base body about a pivot axis,
• wherein the pivot arm can be acted on by a preloading force, by which the third roller is pressed against the second running surface, by a preloading device acting between the base body and a contact point of the pivot arm, and
• wherein the third axis of rotation, the pivot axis and the contact point lie on a straight line,
• wherein the pivot axis is arranged between the third axis of rotation and the contact point.
