The conveyor (10) has two battery cells (38, 40) i.e. lithium cells, integrated in a cavity or inaccessible locations of the conveyor in difficultly removable or not exchangeable manner. One of the battery cells is fixed in an inner side of a wheel arm below a standing platform, into a lifting scaffold (16), or inside a case of a drive portion (12). The lifting scaffold is fixedly connected to a chassis of the drive portion. The battery cells are placed at different locations that are remote from each other.
