STORAGE DEVICE FOR MATERIAL BOARDS

The invention relates to a storage device for material boards (2), having a rail-bound main track (6) and at least one main vehicle (4), which can travel on the main track, and also a plurality of transfer paths (7) that lead to board deposit points (9), and at least one satellite vehicle (5), which can travel on the transfer paths and is able to move at least one material board (2), wherein a holding area (8) is provided on the main vehicle (4) for at least one satellite vehicle (5), wherein the main vehicle (4) has an electrical power supply, for example via a sliding contact, and a drive means comprising a main vehicle electric motor (12), and wherein the satellite vehicle (5) likewise has a drive means comprising a satellite vehicle electric motor (22). In order to make the main vehicle and the satellite vehicle more independent of one another, provision is made for the satellite vehicle electric motor (22) of the satellite vehicle (5) to be able to be supplied with power via an energy store (20) connected to the satellite vehicle (5) and for the energy store (20) to be able to be charged by means of a charging station (17) on the main vehicle (4).
