A device for manipulating a tarpaulin so as to selectively cover and uncover a top aperture of a container the device being usable in combination with an actuator providing a rotational motion, the device comprising: a rod for rolling the tarpaulin therearound and for unrolling the tarpaulin therefrom; a rod rotating component having a substantially elongated configuration, the rod rotating component defining a component longitudinal axis, the rod rotating component being linkable to the actuator so as to be rotatable therewith about the rod longitudinal axis, the rod rotating component being operatively coupled to the rod in a manner such that rotating the rod rotating component about the component longitudinal axis rotates the rod about the rod longitudinal axis, the rod rotating component being pivotable relatively to the actuator and configurable between a component shortest configuration and a component longest configuration.
