A device for manipulating a tarpaulin to selectively cover and uncover a top aperture of a container, the device being usable in combination with an actuator, the device comprising: a rod for rolling the tarpaulin therearound, the rod defining a rod longitudinal axis; a mounting bracket attachable to the container in a spaced apart relationship relatively to the top aperture; an articulated linking element defining a linking element first end and a substantially opposed linking element second end, the articulated linking element being pivotally attached to the mounting bracket substantially adjacent to the linking element first end, the articulated linking element being rotatably attached to the rod substantially adjacent to the linking element second end, the articulated linking element being movable between a first configuration and a second configuration, the articulated linking element being in the first configuration when the tarpaulin is in a retracted configuration, and the articulated linking element being in the second configuration when the tarpaulin is in an extended configuration; and a transmission operatively coupled to the actuator and to the rod for rotating the rod about the rod longitudinal axis when the actuator is actuated.
