Drive systems and/or the like are provided. In some embodiments, a drive system may include a frame; a conveyor configured to wrap around the frame and to rotate relative to the frame, wherein the conveyor defines an effective surface area configured to support and transport one or more objects; one or more rollers configured to drive the conveyor around the frame; a timing belt disposed beneath the frame and configured to support the conveyor as the conveyor rotates relative to the frame; a motor disposed beneath the frame, wherein the timing belt is operably engaged with the motor, and wherein the motor is configured to drive the one or more rollers and the timing belt such that an angular velocity of the conveyor and an angular velocity of the timing belt are equal.

A passenger conveyor includes a first stationary structure and a second stationary structure; a step positioned between the first stationary structure and the second stationary structure, the step has a tread with a tread surface; and a skirt secured to the step between the step and the first stationary structure, the skirt includes an upper tread edge; wherein the upper tread edge extends beyond the tread surface by at least about 10 mm.

A conveyor employs a low-tension, direct drive conveyor belt, and a snap-on position limiter for ensuring proper engagement of the belt and a drive sprocket. The position limiter includes a body, a limiting surface and a snap clap opposite the limiting surface for snapping the position limiter to a mounting shaft. The position limiter may include a mounting arm for mounting a conveyor belt scraper at the front of the position limiter. Mounting plates at the end of the conveyor support a mounting shaft for mounting the position limiter or other conveyor components in place relative to the drive sprocket.

A conveyor mechanism and system are described that provide for conveyance of objects from a first position to a second position. The conveyor mechanism includes a torus-shaped flexible membrane having a central axis, the torus-shaped flexible membrane elongated along a direction parallel to the central axis and having an external surface, center channel, and an enclosed cavity. The conveyor mechanism also includes a first roller assembly disposed within the enclosed cavity of the torus-shaped flexible membrane, a second roller assembly that applies a force against the external surface and the first roller assembly to cause the torus-shaped flexible membrane to rotate longitudinally around the enclosed cavity to convey objects along the center channel, and an adjustment device that adjusts a position of the second roller assembly along a direction parallel with the central axis.

An adaptor for mounting components to a drive assembly for a conveyor belt comprises a shaped body having a bearing opening, fastener openings for fastening the shaped body to an outside surface of an end plate of the drive assembly and openings for mounting an auxiliary conveyor component to the adaptor to place the auxiliary conveyor component relative to the conveyor belt.

A belt conveyor in which a positively driven short pitch conveyor belt is driven around a tight transfer nose roller by a drive arrangement in which a snub roller is positioned between the nose roller and a drive sprocket. A short take-up belt catenary depends directly from the belt's release point from the sprocket to provide back tension for effective sprocket-belt engagement.
