The invention relates to industrial means of transportation. The gravity conveyer having an inlet, an outlet and a multi-loop spiral belt (2) connecting the inlet and outlet, said belt being installed around a vertical axis. The belt (2) is designed as a ferroconcrete surface, each loop of which being square shaped and along which movable gravity driven carts are mounted to run in a preset trajectory and overhead manipulators (7) detached from said carts. Manipulator travel trajectory is determined by a guide attached to the lower surface of the belt (2). The carts travel trajectory is determined by a guide attached to the upper surface of the belt. There are technological stations (5) installed along the belt and the carts and manipulators (7) controlled by a programmable magneto-optical system run and stop relative to said stations (5). A conveyer is invented enabling relevant treatment of the loads transported on the belt, as required by technology.
