Abstract: A parking enforcement device can be secured to a surface adjacent to the area designated as NO PARKING. The enforcement device can include an elongated hollow body, a window provided to the tubular body, a battery, an internal frame assembly disposed inside of the elongated hollow body, and a camera disposed inside of the elongated hollow body. The internal frame assembly defines a cavity in which the battery is located. A camera support pole extends vertically upwards from the internal frame assembly. The camera is secured to the camera support pole and located vertically along the camera support pole such that the camera views outward through the window. A solar panel can be provided atop the parking enforcement device to recharge the battery.

Abstract: A container tarping assembly comprises a frame structure. A left spreader assembly and a right spreader assembly adapted to carry a tarp are also provided.
