The present disclosure concerns a belt conveyor roller wear liner superposable against an outer peripheral surface of a roller cylindrical body, the roller wear liner comprising: a shock-absorbing matrix; and a plurality of inserts, spaced-apart from one another and embedded in the shock-absorbing matrix with external surfaces of the inserts and the shock-absorbing matrix, extending between the inserts, being exposed outwardly, the roller wear liner being substantially ring-shaped. It also concerns a corresponding belt conveyor roller assembly, a corresponding belt conveyor and a corresponding method.

A transfer module assembly includes a frame, a conveyor belt with internal rotating elements, where the conveyer belt is supported by the frame, conveyor drive rollers supported by the frame and configured to drive the conveyor belt, a flat transfer belt mounted beneath the conveyor belt and configured to contact undersides of the internal rotating elements of the conveyor belt in operation, and flat transfer belt drive rollers supported by the frame and configured to drive the flat transfer belt. The conveyor drive rollers are friction-based and operate without use of a sprocket, and comprise depressions for receiving the internal rotating elements of the conveyor belt.

A sound attenuated material handling element reduces vibration and sound in a material handling system. The material handling element may be a sound attenuated roller for use in a roller conveyer or a sound attenuated nestable tote for receiving and transporting articles in the material handling system. Reducing vibration in material handling element reduces the noise produced by the element. The sound attenuated roller includes sound attenuating material disposed inside of the roller and in contact with the inner surface of the roller body. The sound attenuated nestable tote includes sound dampening material disposed in or formed with the tote structure. The sound damping material may be integrally formed with the roller or tote in order to maximize vibration and noise attenuation. Three dimensional computer analysis may be used to determine optimized locations for placement of the sound damping material on the roller or tote.

A drive wheel for a power drive unit of a cargo handling system is disclosed. One aspect of the drive wheel is that it includes one or more wear indicators for a tire of the drive wheel. Another aspect of the drive wheel is that it includes one or more features (e.g., at least one protrusion, alone or in combination with one or more slots) that resists relative rotational movement between the tire of the drive wheel and the hub of the drive wheel.

A conveyor system and drive element for same include a chain including a plurality of links that hinge with respect to each other and a plurality of moving elements such as balls that freely move in the links. A drive element drives the chain in a conveying direction and includes an elongated body with a surface that has a plurality of planar facets arranged around the longitudinal axis of the body. The facets extend along the body and engage respective links of the chain as the body is rotated to drive the chain. Relief elements are located in each facet and are configured for receiving the moving elements of the chain links engaging the facets so the links lie generally flat on the facets when the chain is driven. Other versions of the drive element are faceted for driving a chain with links but without relief elements.
