{"product_id":"6946785126280","title":"3D Mechanical Oil Pump Puzzle","description":"\u003cp\u003eEnter 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 collector’s 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 children’s 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.\u003c\/p\u003e","brand":"RoboTime","offers":[{"title":"Default Title","offer_id":54026169614683,"sku":"6946785126280","price":116.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1787\/2513\/files\/0695146.jpg?v=1789068827","url":"https:\/\/czechmovie.com\/products\/6946785126280","provider":"czechmovie","version":"1.0","type":"link"}
