This 3-in-1 excavator with a hydraulically controlled arm is assembled from 177 parts. It can easily be transformed from an excavator into a crane or a wood loader. Step by step, a small construction unit is created by simply snapping the pieces together. Finally, fill the hoses with water – and the hydraulic excavator can start its work: the excavator arm and bucket can move in three different directions. It features a mechanical chain drive and a swiveling excavator body. With the hydraulic excavator from Revell Engineers, children aged 8 and up can discover how the power of liquids can be used to perform mechanical tasks. The step-by-step instructions guide boys and girls to create a functional model. The necessary tools are also included. This makes technology tangible! This product promotes cognitive and motor skills: - Fine motor skills and handling tools - Concentration, patience, and precise work - Spatial thinking (reading and understanding a construction manual).
