Industrial City Series
Part of the Industrial City collection, this 127-piece mechanical 3D puzzle constructs a detailed oil extractor. The building set requires about three hours of assembly, resulting in a 135x80x243 mm structure. The medium difficulty level provides a straightforward construction process for adults and teenagers utilizing plastic and metal components.
Beam Pumping Unit
The central mechanism replicates a beam pumping unit. Once activated, the red mechanical horsehead moves up and down, driven by the power pulley and a single-cylinder piston engine. These visible metal and plastic gears, along with the moving counterweight, demonstrate the continuous mechanical operation of the oil extraction process.
LED Illumination System
Integrated LED components light up the structure during operation. An orange light glows inside the transparent fuel tank located in the center of the tower. A secondary red light sits near the steam energy boiler section, illuminating the moving gears and the surrounding mechanical parts while the motor runs.
Dual Power Modes
The oil pump operates via two distinct power configurations. The wireless mode utilizes a direct Type-C power connection. Alternatively, the track mode allows the device to draw power directly from a connected base. The design supports physical linkage with other compatible models from the same mechanical art series.
Touch Control System
A touch-sensitive area on the base controls the active functions. A single click simultaneously starts the internal motor and all LED lights. A second click stops the motor, while a third click turns off the lights completely. A long press enables a specialized single-device control mode for isolated operation.
