A conveying system for transporting loads utilizes a transport cart that is supported by rollers. The transport cart is supported by the rollers adjacent several serially arranged revolving drives that each have a plurality of spaced recesses. At least one pusher is carried by the cart and engages a recess in the drive. The cart can be halted, if its path is blocked, by disengagement of the pusher from the recess in the drive.
