Hydraulic Crane Kit - DIY Mechanical Build

Short Product Description

Build a fully functional hydraulic crane using syringes and water-powered actuators! Kids explore real hydraulic principles by assembling a crane that lifts, lowers, and moves objects with fluid pressure.

How It Works

Fill the syringes with water and connect them using the tubing system.
When kids push one syringe, water transfers force to another—creating smooth lifting and lowering motion in the crane arm. This hands-on model demonstrates hydraulics, force amplification, and controlled movement just like real construction machines.

What Kids Learn

• How hydraulic pressure and fluid force work

• Mechanical advantage & force amplification

• Linkages, joints, and real-world crane mechanisms

• Problem-solving, precision assembly & fine motor skills

• STEM concepts through fun, interactive lifting challenges
