  • Patent number: 4681211
    Abstract: Disclosed herein is a transport device for piece goods or the like, having rolling members (5) which directly support the piece goods. The rolling members (5) are arranged partly below a plate member which may be a unitary plate or segments (1) which supplement each other in plate-like manner. The rolling members (5) are supported on rolling drive devices and are guided in holes (3) in the plate member. The top portions of the rolling members (5) protrude above the top of the plate member and are arranged in linear rows (7) transverse to the direction of the transport. The transport device is a linear conveyor device which has simple drive devices, insensitive to heavy loads, on the rolling members (5) and, accordingly, can be driven over also by vehicles without the lowering of the rolling members (5). This result is achieved by providing the rolling drive devices in the form of cylindrical shafts (8) one of which is mounted centrally below each row (7) of rolling members (5) and parallel thereto.
