Tonka crane DIY wooden toy

The Tonka DIY Truck with Crane will provide hours of fun play time for your little one! The truck can be built using the pieces (which includes spanner and screwdriver), and a magnetic arm is used to collect blocks with the crane. The crane takes this a little further: one can observe how the winch diameter affects lifting speed and power, and the very useful principle of mechanical advantage gained by the two pulleys. When this is taught in schools, it is normally not easy for kids to really get it as a concept; how the addition of pulleys increases the lifting power and reduces the speed. More often than not they only wind up memorizing formulas so they can pass the test and forget about it. But by making and playing with one themselves, they can see first-hand what actually happens when you add pulleys. They no longer need to memorize anything – they just know it.
