Tall and Proud

The Oil Extractor'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.

Power Pressure Reducing Valve

Voltage regulation & stable output.

Counterweight Balance Block

Gravity hub repeats rotation.

Steam Energy Boiler

Orange-yellow flame, simulated combustion.

【Industrial Revolution Legacy】Born from the global oil boom, this meticulously engineered model recreates the iconic "nodding donkey" pumpjack that revolutionized automated oil extraction. Standing 9.5 inches tall, it embodies industrial heritage through its steam-powered piston mechanism and coordinated gear train.

【Dynamic Mechanical Operation】Witness the authentic rhythmic motion of the cantilever beam driven by a precision gear system. The synchronized movement demonstrates actual pumpjack mechanics through four operational components: swinging cantilever, rotating pressure valve, counterweight block, and pressurized boiler.

【Dual-Power Connectivity System】Integrates seamlessly with other Industrial City models through wireless or rail-type power base connections. This interoperability allows synchronized activation across multiple mechanical structures, enabling expansive desktop industrial landscapes.

【Authentic Industrial Aesthetics】Features exposed gear mechanisms, functional LED lighting, and distinctive red-silver metallic finish that capture classic industrial design. The detailed construction showcases operational components including reduction valves and pressure systems.

【Educational Mechanical Display】Serves as both collectible display and functional demonstration of petroleum extraction technology. The working model illustrates fundamental principles of industrial machinery through its visible piston action and beam pumping motion, offering STEM learning opportunities.
