3D Mechanical Oil Pump Puzzle

Enter the world of the Industrial Revolution with a detailed mechanical 3D model that brings the principles of oil extraction to life. Inspired by a historic drilling machine, it features realistic movement and an ingenious mechanism. The model faithfully imitates a pumpjack, a device that automated oil extraction. A system of gears and a piston creates the characteristic rocking motion of its arm, making it both an appealing model and a functioning demonstration of mechanics. Its industrial-era design includes visible metal-look elements, LED lighting simulating combustion, and details such as a pressure valve and steam boiler. The finished model serves as an eye-catching decoration and a collectors piece. It is part of the Industrial City series, whose models can be connected to create a moving mechanical city. The puzzle contains 127 pieces, takes approximately three hours to assemble, and includes a display base. It has a medium difficulty level, develops logical and motor skills, supports childrens patience, and is suitable for children and adults. The mechanism is powered via USB and includes a crank mechanism, counterweight, pressure valve, piston movement, and realistic rocking motion simulating oil extraction, while the steam boiler features an LED combustion effect.
