The Ravensburger GraviTrax Power Element Elevator expands your marble run system with an automatic lift staircase. This electronic accessory transports multiple marbles simultaneously and fully automatically upwards, overcoming a height of up to seven height blocks. The motorized element integrates seamlessly into existing GraviTrax starter sets and ensures a continuous flow of marbles without the need to reset them by hand. Thus, the STEM-based toy supports the understanding of physical principles and encourages the creative construction of custom tracks.
