摘要： A door (1 ) comprising a tarpaulin (2) and control means (3) for controlling the raising or lowering of said tarpaulin to open/close said door, said control means comprising at least one electric direct current motor (4) provided with one stator (4a) and one rotor (4b) mechanically combinable, directly or indirectly, with said tarpaulin (2), and at least one control unit (5) for controlling the operation of said electric motor (4), said control means (3) being further connectable, directly or indirectly, to an electric power-supply device (6) for converting the alternating current of the network to direct current for the direct-current supply of said control unit (5) and said electric motor (4), at least during the raising of said tarpaulin by rotating said rotor (4b) of said electric motor in a first direction, characterized in that said control means (3) further comprise at least one battery (7) functionally connected in series between said electric power-supply device (6) and said control unit (5) so that the weight of said tarpaulin (2), at least during its lowering, causes the rotation of said rotor (4b) of said electric motor in a second direction and the simultaneous charging of said at least one battery.
