A plate conveyor for moving walkways contains a track system having tracks, which track system is formed by track elements, and a central track serving as a guide for plate conveyor elements of the plate conveyor. The length of the track system can be adjusted. For this purpose, substantially triangular openings which are delimited by bars are provided between track elements that adjoin one another. Triangular or trapezoidal length adjusting pieces are inserted into the openings and are pushed in to such an extent that the oblique edges of the length adjusting pieces abut the edges of the openings formed by the bars. The central tracks of the track elements that adjoin one another are connected to one another by coupling pieces.

A spiral conveyor for positively driving a conveyor belt along a helical path. The spiral conveyor includes a rotating cylindrical tower with parallel drive members extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge that varies in height from the bottom to the top of the tower. The variations in height facilitate the belt's entry onto and exit from the tower and robust, positive driving engagement with the inside edge of the belt along the majority of its path along the tower.

Provided is a conveyor belt link, of the type used in endless conveyor belts assembled from a plurality of such modular conveyor belt links, where the modular conveyor belt link has a main body extending in the modular belt link's width direction, and where a plurality of eye parts extend forwards and rearwards from the main body, the eye parts being spaced in the width direction of the modular belt link, where forwards extending eye parts are offset relative to rearwards extending eye parts, such that when two modular conveyor belt links are pushed together the eye parts on one link will inter-fit between eye parts on the other modular belt link, wherein the modular belt link laterally is limited by two sides, and that the outermost eye parts on either side are provided with a cutout, such that the width of the modular conveyor belt link is smaller in the cutout than outside the cutout.

A spiral conveyor having a self-stacking conveyor belt positively driven on a helical path up or down a drive drum. Stacker supports at opposite sides of the belt support the tiers above. Locking structure on the outer stacker supports interlock consecutive tiers. Drive members on the drive drum have a belt entrance segment and a positive-drive segment. The positive-drive segment has ridges that engage the inner side of the belt without slip. The entrance segment provides a smooth reduction in drum diameter without drive ridges to multiple belt tiers entering the helical path.

An active drive spiral conveyor belt system includes a drum configured to rotate about a drum axis, a plurality of modules, a plurality of cross-rods joining together the plurality of modules, and an infeed system. The drum can include a plurality of drive bars, each with a drive member extending therefrom, and spaced an arc length. At least some of the plurality of cross-rods or modules can include a drive end configured to engage with the drive members. The plurality of modules can be configured to be collapsible relative to each other and the plurality of cross-rods. The infeed system can be configured to collapse the spacing between adjacent drive ends prior to transiting into engagement with a cooperating drive member.

The present invention relates to conveyors, comprising at least one circulating conveyor strand (7, 8), wherein the conveyor strand has at least one clamping connection (1), wherein at least one sensor (2) is arranged in the clamping connection (1), a transmitter (3) for wirelessly transmitting data is arranged on the conveyor strand (7, 8), the sensor (2) is connected with the transmitter (3), and a receiver (4) for receiving the data transmitted by the transmitter (3) is provided.

A support and guide structure for a closed-loop articulated link conveyor includes at least two guides, oriented according to respective development axis and defining respective sliding surfaces for the conveyor; and at least one support component having two surfaces opposite to each other, wherein the guides protrude from a first surface to define at least one sliding channel to house at least one portion of the articulated links of the conveyor. The support and guide structure includes at least one housing extending along a direction parallel to the development axis, and containing at least one respective reinforcing element to limit the deformation of the support component. Each reinforcing element has a cross-sectional shape compatible with the cross-sectional shape of the respective housing. Each reinforcing element is manufactured with a material having a hardness which is greater than the hardness of the materials of the guides and the support component.

A spiral conveyor construction comprises an endless conveyor belt guided on a conveying path. At least a part of the conveying path surrounds a drive tower. Spaced along the periphery of the drive tower are arranged vertical engagement members. Additionally on a lower section of the drive tower adjacent blocks are provided, radially projecting further from the drive tower than the engagement members, and where the blocks are provided with a radially extending secondary rib.
