Overview
The ROKR Oil Extractor Mechanical 3D Puzzle recreates the iconic "nodding donkey" oil pump jack for ROKR's Industrial City Series. When industrialization boomed, so did demand for oil, and this machine automated extraction for better efficiency. ROKR's 127-piece wooden version brings its rhythmic rocking motion to your desk or shelf.
A coordinated gear train drives the piston pump, bringing four moving elements to life: the swinging walking beam, a spinning pressure valve, the counterweight block and a simulated boiler with flame effect.
