A conveyor belt assembly may include a conveyor belt having an elastomeric layer, a chain adjacent a side edge of the conveyor belt and a flexible bridge extending between and connected to the chain and the conveyor belt along the side edge. The chain, bridge and conveyor belt may be driven to revolve by a sprocket engaging the chain.

The present invention provides a rail conveyor system of the type having a rail track (9) including a delivery run (1) extending between a loading end (5) and a discharge end (6) and a return run (12) extending from the discharge end (6) to the loading end (5), a plurality of carriages (8) spaced apart from one another and arranged to run on wheels (24) supported by the track (9), and a continuous carry belt (10) supported by the carriages (8); wherein, at least at the discharge end (6), the carriages (8) are turned around to return to the loading end (5) by being entrained around only one or more vertical turnover wheels (7) arranged such that the carriages (7) are delivered to the return run (12) beneath the delivery run (1).

Zero tension system conveyor. A conveyor belt is driven by at least a portion of the conveyor belt being in continuous contact with a block chain within at least a portion of an overall conveyor belt system. Such a conveyor belt system may be implemented in a spiral configuration such that a relatively small portion of the overall width of the conveyor belt is in contact with the block chain above and/or below the conveyor belt. The static force/weight of the conveyor belt in conjunction with the continuous contact between at least a portion of the conveyor belt and the block chain effectuates the driving of the conveyor belt through the overall conveyor belt system. The block chain is composed of a number of links, at least some of which include a respective hook/protrusion on one side thereof, for being directly engaged by drum bars implemented within a drum assembly.

The present invention relates to a method by means of which conveyor belts of belt conveyors, which can be loaded with a bulk material, have their operational behaviour and/or state and/or loading monitored during operation, wherein the belt conveyor has provided on it at least one radar-antenna combination, which consists of at least one transmitting antenna and one receiving antenna and is oriented onto the conveyor belt, wherein a radar-antenna combination arranged to the side of the conveyor belt periodically picks up the reflection from emitted radar beams by way of the side edge of the conveyor belt and/or the loading boundary of a bulk material located on the conveyor belt and communicates corresponding signals to a signal-processing unit, whereas a radar-antenna combination oriented onto the surface of the conveyor belt periodically picks up the reflection of emitted radar beams, on the one hand, by way of the surface of the conveyor belt and, on the other hand, by way of reinforcing supports embedded in the conveyor belt and communicates corresponding signals to a signal-processing unit.
