ABSTRACT:
A fumigation tent comprises a frame that can be suspended from the roof of a dock building by support cables. The frame has an underside to which a tarp is mounted. The tarp hangs from the frame defining a tent having a top and side curtains having a lower periphery that defines a bottom perimeter. Horizontal pipes are attached to, and arranged along, the side curtains of the tent at spaced intervals between the bottom perimeter of the tent and the top of the tent. Winch cables attached at one end to clew plates draw up the horizontal pipes. The clew plates can accommodate several winch cables and are connected by winch chains to motorized winches which operate together so that the tent remains substantially level when it is raised and lowered. Rings, disposed around the winch cables and attached to the horizontal pipes, gather up and support the tarp as the tent is being raised. The rings cooperate with the horizontal pipes to collect the tarp into a plurality of small bagouts or overhanging portions. A system comprising a flexible water hose mounted along the bottom perimeter is provided for sealing the tent to the floor of the dock building.
