Conveyor device with at least two conveyor carriages and a powertrain brake for a cross belt conveyor on at least one of the conveyor carriages

A conveying device having:

• at least one first and one second conveying carriage which are arranged one behind the other in a conveying direction,
• a transverse-belt conveyor which is formed on at least the second conveying carriage and which serves for conveying material for conveying in a transverse conveying direction oriented substantially transversely with respect to the conveying direction, and
• a drivetrain brake for the transverse-belt conveyor,
• wherein the drivetrain brake has a brake apparatus and an operating apparatus for the brake apparatus, wherein the operating apparatus is arranged on the first conveying carriage and the brake apparatus is arranged on the second conveying carriage,
• wherein the brake apparatus can be placed into a braking state in which the brake apparatus exerts a braking force on an element of a drivetrain of the transverse-belt conveyor, and can be placed into a release state, in which the brake apparatus exerts no or a reduced braking force on an element of a drivetrain of the transverse-belt conveyor,
• wherein the operating apparatus and the brake apparatus interact such that, during substantially straight-ahead travel of the first and second conveying carriage, the brake apparatus assumes the release state and, during travel of at least one of the conveying carriages around a curve, the brake apparatus assumes the braking state, in order to allow a movement of a transverse belt (16) of the transverse-belt conveyor in the transverse conveying direction during straight-ahead travel and to brake such a movement during travel around a curve.
