Description

Demonstrate the fascinating principles of hydraulics using the complete hydraulics model kit.

We found this wonderful hydraulics model in China – it’s not widely available in the USA. This science model kit includes everything you need – including the screwdriver. Instructions are written in Chinese but includes a picture for each step that makes assembly easy to follow along.

Build your own hydraulic excavator to demonstrate the principles of this fascinating area of engineering. Kit includes sturdy wooden pieces you snap out of the panel. Attach and screw the pieces together as shown in the included pictures. Includes hydraulic syringes, pistons, axles, bushings, sleeves, wood file, screws, and screwdriver.

  • Hydraulics model kit includes everything you need to create a hydraulics demonstration
  • Sturdy wooden model
  • Screws and screwdriver
  • 9 hydraulic pistons (syringes to drive the hydraulic action and pistons)
  • Bushings, axles, and sleeves
  • Wood file to smooth out edges of the wood

Hydraulic systems work by using pressurized fluid to power an engine. These hydraulic presses put pressure on a small amount of fluid in order to generate a large amount of power.

In this hydraulics demonstration, water in a contained system has pressure put on it from one side (the syringes). That pressure forces it against a piston on the other side of the container. This transfers the energy into the piston, forcing it upward to lift the arm. Because the pressure on the water will not let it flow backwards, the piston can never move in the opposite way unless that pressure is released. This means that whatever the piston is lifting is secure until the system operator allows it to be released. It’s the driving principle behind fork lifts, car brakes, and construction equipment.
