A construction kit that combines solar power with hydraulic mechanics to build twelve different working machines — crane, bulldozer, forklift and more. The solar panel powers the pump, which moves water through hydraulic cylinders to create movement — the same mechanism used in real construction machinery. Children build each configuration, discover how hydraulic force works and then rebuild into something completely different. A genuinely impressive STEM project that demonstrates real engineering principles.
Because this kit goes significantly further than a standard building kit — it introduces hydraulic mechanics alongside solar power, combining two real engineering systems in a way that genuinely teaches how construction machines work. The 12 configurations give exceptional longevity and replay value.
