Oil Pumpjack Diagram - How a Nodding Donkey Works in Petroleum Extraction #195293 (License: Personal Use)

This technical illustration depicts a conventional beam-type oil pumpjack, featuring a red A-frame structure, yellow walking beam, counterweights, and a black prime mover with belt drive. The sucker rod string extends downward through the wellhead to the downhole pump, enabling reciprocating motion for lifting crude oil to the surface. Key components like the horsehead, polished rod, and gear reducer are clearly rendered for educational or engineering reference.
