Abstract
A crossover conveyor system that allows people to safely cross over a portion of a conveyor line is disclosed. The crossover conveyor system includes a frame that has at least a first side member and a second side member. A plurality of rollers may be connected between the first and second side members. A first and second drive shaft may be connected between the first and second side members at opposing ends of the frame. At least one endless belt extends or wraps around an upper surface of the frame, the rollers and the first and second drive shaft. A drive belt may be connected with a drive mechanism. Pressure rollers are included for constantly applying pressure to the drive belt or selectively applying pressure to the drive belt. The drive belt is located between the endless belt and the pressure rollers such that when the drive mechanism rotates the drive belt and the endless belt rotates.
