Abstract
The invention relates to an overhead conveyor system which includes a rail, at least one carriage which is provided with wheels and which is adapted to run along the rail and support a load suspended from the carriage, a rotatable drive shaft which extends along the rail and is located perpendicularly above the rail, and a drive arranged on each carriage and adapted to drive, in contact with the drive shaft, the carriage along the rail. The drive includes at least one wheel which is inclined relative to the longitudinal direction of the drive shaft and has a contact surface spring-loaded against the drive shaft, the spring load of the drive being independent of the load suspended from the carriage.
