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.

A system for automatic organization, hanging and driving of slaughtered animals installed at the outlet of a slaughtered animals processing station such as a chiller. The system comprises a receiving and aligning means of slaughtered animals in longitudinal position, which is previously disposed to an accumulator device of slaughtered animals positioned longitudinally. The system further comprises a suspension and movement assembly of each slaughtered animal from the axial alignment assembly to a driving guide of each slaughtered animal to a hanging transfer device of each animal slaughtered in the hanging line.

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.

A freezing spiral net chain structure includes a plurality of chain links successively arranged in a travelling direction of a rail. Transmission teeth are arranged at inner ends of the chain links. Engagement teeth are arranged at two sides of the chain links. The engagement teeth of the adjacent chain links are engaged with each other. Axial holes are disposed between the mutually engaged engagement teeth. Rotary shafts are inserted into the axial holes. A metal piece is connected between outer ends of every two adjacent rotary shafts. The metal piece may bear a load from an outer-end spiral net, and since a coefficient of expansion of metal is smaller than that of plastic, deformation between the adjacent rotary shafts as a result of cold shrinking is reduced. The metal piece is different from the rotary shafts of the plastic spiral conveying net chain in terms of pitch.

A transport attachment (1) for a plate conveyor (100; 200) for conveying material includes a transport plate (50) for conveying the material on a transport surface (10) of the transport plate (50). A connection device (40) has a fastening element (42) for fastening the transport attachment (1) to a driven traction element (150) of the plate conveyor (100; 200). At least one lateral supporting surface (41) is used for laterally supporting the transport attachment (1) in a curve of the plate conveyor (100; 200).
