Abstract
A two-track conveyor system includes an I-beam-shaped power track and a channel-shaped free track, where the power track supports a heavy-duty chain drive having a pusher dog with a pivotal connector. By providing the pusher dog with the pivotal connector the pusher dog can be used with a load-bearing trolley, that rides within the free track, that has a fixed power dog at the front end of the leading trolley and that does not require a hold back dog.
