Build a realistic excavator model and discover the power of hydraulics without batteries. This smart STEM set with 130 parts for children aged 8+ offers arm movement powered by water pressure, a 360° rotating platform, and plenty of functional moving parts for fun learning and hours of play.
Water-powered, no batteries needed
The hydraulic system converts water pressure into smooth movement of the arm and bucket—safe, eco-friendly, and fun.
Realistic functions like a real machine
A 360° rotating platform, boom movement, stick and bucket with precisely defined angles for authentic control.
Learning through play with STEM
Kids develop logical thinking, patience, and understanding of the physics behind hydraulics while building and playing.
The buildable hydraulic excavator is an educational kit that clearly shows children how water hydraulic pressure converts force into motion. Once assembled, it needs no batteries—the control levers and water set the arm, boom, and bucket in motion just like on a real construction machine.
Kids practice logical thinking, dexterity, and grasp fundamental physics principles. Realistic features including a 360° rotating platform, adjustable angles, and track movement deliver an authentic “jobsite” experience.
- No batteries — powered by water and control levers.
- Realistic movements — raise and lower the arm, move the boom and bucket.
- STEM learning — a fun path to science and engineering.
- 130 parts + pictorial manual and decorative stickers.
