With modular assembly and a digital step-by-step guide, it’s designed for independent, playful learning that brings engineering concepts to life.

## Description

Explore hydraulics and engineering with build your own hydraulic crane hydraulics utilizes liquids through varying pipes and channels to move large amounts of weight. By putting the liquid under pressure, such as in a cylinder, a very small device can lift a large amount of weight. In order to illustrate this, you can design an experimental hydraulic crane. Explore hydraulics and engineering with build your own hydraulic crane if you've read how hydraulic machines work, you know that the hydraulic crane is based on a simple concept -- the transmission of forces from point to point through a fluid. Most hydraulic machines use some sort of incompressible fluid, a fluid that is at its maximum density. Oil is the most commonly used incompressible fluid for hydraulic machines, including hydraulic cranes. In a simple hydraulic system, when a piston pushes down on the oil, the oil transmits all of the actual force to another piston, which is driven up. To operate, you push in the plastic cylinder-piston with water, so that the connected empty plastic cylinder-piston moves up the piston. This in turn pushes the wooden stick up. Depending which cylinder-piston you push makes that part of the crane move.

Review: Nice functionality - Nice build quality with beautiful functionality. Use with different colour water for each syringe adds to the fun. Be careful not to spill water on cardboard as it gets damaged when wet.
