Hay pulley / Shaeve wheel
DeepWiki – The well service authority

Hay pulley or Shaeve wheel is a pulley that is normally attached to the wellhead at a convenient place for the wireline to pass through as it comes from the stuffing box sheave before being spooled onto the wireline reel.

The hay pulley prevents any lateral force from being exerted on the lubricator and the wellhead.
