Oil Extractor Mechanical 3D

ROKR Oil Extractor Mechanical 3D Puzzle, ROECGL03 When industrialization boomed, so did the global demand for oil. Thus was born the nodding donkey, an invention that automated the oil extraction process for better efficiency. ROKR replicates this tall machine for its Industrial City Series with an impressive depiction of a steam-powered pumpjack all set to harvest tons of liquid gold from underground. It stands at 243mm (or about 9.5 inches) tall and uses a coordinated gear train to activate the piston pump that powers its cantilever's rhythmic motion. This standout piece can be activated in sync with other Industrial City models through its wireless receiver or its rail-type power base hub. Features: Tall and Proud: The Oil Pump Jack's exposed gears, LED lamps, and red-and-silver metallic coloring create an industrial look. Mechanical Art, Free Connection: Two connection methods: Wireless or by rail, connect multiple models to build a city on your desk. Traveling Beam Bending Device: The crank connecting rod drives the head torise and fall, a realistic demonstration of oil extraction in industrial civilization. Four-Part Automated Pump: This model features four main parts: the rhythmically swinging cantilever, the spinning pressure reduction valve, the counterweight balance block, and the pressure boiler. Specifications: Number of pieces: 127 Assembly time: 3h Difficulty level: 3 of 5 Assembled size: 4.4x3.7x10 Inches Recommended age group: 8+
