A conveyor suitable for conveying objects along a transport direction, and related links, are disclosed. The conveyor includes a plurality of connected links, each link having a length extending across the direction of transport and a width extending along the direction of transport. Each link also has a body, a cam follower member, and at least one gripping member. A gear drive mechanism may be used to interconnect the cam follower member and the gripping member. The cam follower member is movable to selectively move the gripping member between a first position and a second position. The gripping member when in first position is disposed in an open position, and the gripping member when in the second position is disposed in a gripping position for contacting one of the objects to hold the object during transport. Gear-drive mechanisms of various designs may be used to interconnect the cam follower member and gripping member. A releasable holding member, such as a spring-loaded ratchet member, may be used to secure the gripping member in the second position. Multiple opposed gripping members may be used. Various modifications and options are possible.
