A plastic one-piece conveyor drive chain link (40). The link embodies a plastic body (42) having lateral outwardly projecting flanges (44, 46) on each side of the body, upper and lower projections (52, 54) at the distal and proximal ends respectively of the body, and an upstanding locking lug (58) at its proximal end for removable articulated connection and engagement of each link with the next to form an endless drive chain for a conveyor system. The plastic linkage requires no lubrication, is quiet in operation and, because of lower weight, requires considerably less energy for its actuation and movement than is necessary for currently conventional steel monorail conveyor drive chain systems. Preferred embodiments of the invention also include chain links having a lateral outwardly projecting flange or spoke (154) on only one side of the chain link body instead of on both sides, depending upon the direction(s) taken by the monorail conveyor system, and one or more vertical slots through the body to accommodate the locking lug (58), which may be vertically upwardly or downwardly applied, and the pendant of the monorail conveyor trolley. |
