6-in-1 Construction Machinery Kit with Water Hydraulic Drive, 223 Pieces, for Kids 8+

Water hydraulics without batteries
Safe and eco-friendly water power controls lifting, gripping, and lowering. Kids learn the basics of physics and mechanics through truly functional play.

6 models in one set
Build an excavator, loader, fire truck, crane, grapple, and bulldozer. Easy rebuilding using the included detailed step-by-step instructions.

Realistic functions and movement
A 360° rotating superstructure, rubber tracks, and articulated arms with booms give the models an authentic look and behavior during play.
This educational construction kit introduces kids to the principles of hydraulics and mechanics through play. Using 223 components, you can build 6 functional models: an excavator, loader, fire truck with platform, crane, grapple, and bulldozer. All models share a 360° rotating superstructure and a tracked chassis with rubber tracks for smooth movement.
Water-actuated hydraulic cylinders provide realistic actions – gripping, lifting, and lowering. A detailed manual for each model is included, so kids can practice logic, dexterity, and patience while enjoying lots of battery-free fun.
What you can build:
- excavator (movements: arm, boom, and bucket)
- loader (arm and bucket)
- fire truck (platform lift up/down)
- crane (lift, boom, arm)
- grapple (jaws open/close, lift)
- bulldozer (blade lift)
