About this product

Bring the fascinating rhythm of heavy industrial machinery to your collection with the ROKR Oil Extractor CGL03 , an interactive mechanical model from the ROKR Industrial City Series . Inspired by the classic oil-field pumpjack , commonly known as a “nodding donkey,” this detailed 127-piece DIY model recreates the distinctive repetitive movement used in traditional oil extraction systems. Once assembled and powered, an interconnected gear-driven mechanism operates the piston pump and cantilever arm, producing the characteristic up-and-down pumping motion associated with real oil-field machinery. The coordinated movement transforms the completed build from a static miniature into an animated demonstration of mechanical engineering. Constructed from a combination of plastic and metal components , the CGL03 is designed to provide precise movement and a satisfying hands-on building experience. Standing approximately 24.3 cm tall , its distinctive industrial silhouette makes it an eye-catching display piece for a desk, shelf, workspace, or mechanical model collection. As part of the expandable Industrial City Series, the Oil Extractor can also be integrated with other compatible models
