What is a Pusher Dog?

Pusher dogs engage retractable dogs on free line trolleys to push the trolley through the power portions of Power & Free conveyors. Pusher dogs are assembled to Rivetless chain in place of lower side links at specified intervals between power trolleys.


Pusher dogs are hardened and tempered steel forgings. Pusher dogs are usually furnished assembled to chain but can be ordered separately.
