A conveyor system, at least a portion of which may traverse a continuous slope sufficiently steep such that tensile forces associated with overcoming the effects of the slope are several times larger per unit length of run than tensile forces per unit length of run due to main frictional resistance of the conveyor system, may include a belt-on-belt drive. The belt-on-belt drive may include at least one internal belt configured to operably engage the carry belt of the conveyor system so as to frictionally drive the carry belt over at least a one-third length of the sloped run. At the portion of the external belt driven by the at least one internal belt, the rate of tension change in the external belt may be configured to be approximately zero or a modest rise. In some embodiments, the longitudinal stiffness of the at least one internal belt may be substantially greater than the external belt's longitudinal stiffness.

A conveyor for suspended objects has a first rail profile having a first, upper track and a second track arranged below the first track, a conveyor chain having lateral friction roller pressing surfaces to drive the conveyor chain continuously in the first track. Holding adapters for conveyed objects are coupled to the conveyor chain, with the holding adapters being transferred into the first rail profile by an induct switch. A pressing piece arranged on a side of the conveyor chain opposite the drive roller is adjustable between an active and a passive position. The adjustment path of the pressing piece is dimensioned such that in the active position the conveyor chain is in contact with the drive roller and in the passive position the conveyor chain is not in contact with the drive roller, whereby in the active position the drive roller can be driven by the conveyor chain.

The belt-on-belt drive may include at least one internal belt configured to operably engage the carry belt of the conveyor system so as to frictionally drive the carry belt over the sloped run. The longitudinal stiffness of the at least one internal belt may be at least twice the external belt's longitudinal stiffness. At the portion of the external belt driven by the at least one internal belt, the rate of tension rise in the external belt may be configured to be approximately zero or a modestly higher rate.

A handrail drive for driving a handrail of a person-transporting device has at least one drive device and at least one counterpressure device. The counterpressure device contains at least one loading device and at least two counterpressure rollers, wherein the handrail can be guided between the drive device and the counterpressure device. The counterpressure rollers load the handrail against the drive device by a pressing force caused by the preloading force of the loading device. At least one flexible pulling element is arranged between the at least one counterpressure roller and the loading device, by which flexible pulling element the preloading force of the loading device can be transferred to the at least one counterpressure roller.

A turning system for a belt transport system, wherein the belt of the same is formed by a plurality of pallets and the transport system has a turn input stretch and a turn output stretch, arranged on the same horizontal plane. The turning system has a curved stretch, which connects the turn input and output, the curved stretch being arranged on the same horizontal plane as the turn input and output.

In order to be able to reduce the number of required drive units in a multi-track slicing machine, in particular a multi-track slicer, for slicing a plurality of calibers simultaneously into slices, according to the invention second driven product guides for the, in particular all, tracks can only be driven together and have a freewheel unit acting in the feeding direction of the calibers.
