A tarping apparatus including a base frame, a tarp support boom assembly and a drum member. The base frame includes an inner side and an outer side opposite the inner side. The tarp support boom assembly includes a boom member having a proximal end and a distal end. The proximal end is coupled to the base frame and the distal end extends outwardly therefrom beyond the inner side of the base frame. The drum member extends around the boom member and is rotatable about an axis defined by the boom member. The drum member includes a first end corresponding to the proximal end of the boom member and a second end corresponding to the distal end of the boom member. A tarp positioned over the drum member can be rolled up on the drum member through rotation of the drum member relative to the boom member.

A convertible tarp system provides an extendable and retractable enclosure especially suited for covering a flatbed trailer. The convertible tarp system includes a plurality of bows and trolleys that support a tarp structure. A guide track defines a longitudinal path of movement and supports the trolleys for movement along the longitudinal path. The guide track is configured to substantially restrict lateral movement of the trolleys along the longitudinal path.
