A modular plastic conveyor belt constructed of a series of block-shaped belt modules. The belt has drive elements along its left and right sides for side-driving by a sprocket or drive belt. The top side and the bottom side are flat, devoid of drive structure, and provide high impact resistance and reversibility. Hinge elements along leading and trailing sides have circular hinge-pin holes or elongated oval holes that allow the belt to collapse under low tension.

In one embodiment of the present disclosure, a drive chain system (22, 24) for a spiral conveyor belt (34) includes inner (52) and outer (62) drive chains driving the spiral conveyor belt, the inner and outer drive chains each including a plurality of links (70) defined by a plurality of first (72) and second (74) pitches connected by linking pins (84, 86) extending through holes (80, 82) in the pitches, wherein at least a portion of the linking pins of at least one of the inner and outer drive chains are hardened and/or dissimilar linking pins which are harder on an outer surface than other components in the inner and outer drive chains.

A conveyor device (100) includes a conveyor track (11, 12, 13) and a plurality of transport units conveyable along the conveyor track (11, 12, 13), at least two first guide rollers (2.1-2.7) and a conveyor chain (3), which travels over the at least two first guide rollers (2.1-2.7) and comprises catches (31), via which the conveyor chain (3) can be brought into releasable engagement with the transport units (8) for driving the transport units (8), the conveyor device (100) further including a belt (4) moving along with the conveyor chain (3) over the at least two guide rollers (2.1-2.7), wherein the belt (4), in the respective area of the first guide rollers (2.1-2.7), is arranged, respectively, between the first guide roller (2.1-2.7) and the conveyor chain (3) such that the conveyor chain (3) lies against the belt (4).

A friction-type drive apparatus and a carousel comprising the same are disclosed. A friction-type drive apparatus, according to one embodiment, comprises: a motor; a drive pulley rotated by the motor; a belt connected to the drive pulley; a driven pulley rotating in accordance with the drive of the belt; a pressing unit contacting the inner surface of the belt; and an elastic unit for pressing the pressing unit toward the belt.

A wire drive conveying apparatus is configured to cause a conveyance bogie to run along a guide rail by pulling a wire placed along the guide rail and formed to be endless when the opposite ends of the wire are connected to the conveyance bogie configured to slidably engage with the guide rail. The wire drive conveying apparatus includes: a movable trestle connected to a moving pulley configured to support the wire; a weight configured to pull the trestle in a direction in which a tensile force is given to the wire; a spring provided between the conveyance bogie and the trestle; and a locking mechanism configured to permit a movement of the trestle in the direction in which the tensile force is given to the wire and to prevent a movement of the trestle in a direction in which the wire is loosened.

A spiral conveying mesh chain which pertains to the field of conveying equipment includes a conveying mesh chain main body. The edge of the inner side of the conveying mesh chain main body is uniformly provided with passive teeth. The passive teeth are used to engage with driving teeth on the outer periphery of a rotating drum for driving the conveying mesh chain main body to rotate. The contact surface of the passive tooth and the driving tooth is one item selected from a group consisting of an inclined surface, an arc-shaped surface, a V-shaped contact surface, and a T-shaped contact surface, so that the force direction between the passive tooth and the driving tooth is inwardly deviated relative to the rotation direction of the conveying mesh chain.

A support link for a self-stacking spiral conveyor belt, which includes a carrier on which a self-stacking spiral conveyor belt is supportable, a set of orthogonally arranged rolling elements connected to the carrier, in use to guide the carrier along a conveyor path and an interlink mountable onto the carrier. The interlink is connectable to a matched interlink of an adjacent support link through couplers disposed on opposing ends thereof, whereby the connection of a plurality of support links results in a support chain. Furthermore, there is provided a supporting frame defining the conveyor path on which the support chain is movable and a motor driving the support chain by means of a drive gear, which interacted with a drive interface disposed on each support link.
