ABSTRACT:
Apparatus to temporarily enclose multi-story structures such as municipal water towers during sandblasting and painting to thereby contain the debris and overspray from the environment. A plurality of booms extending in an array outwardly from the top of the structure are temporarily attached to the structure. Hoisting and guide cables extend downwardly from the ends of the booms out beyond the outermost periphery of the structure. A plurality of fabric or plastic panels are supported on a framework in turn attached to guides on the guide cables and the guides are attached to the hoisting cables. The guide cables are anchored to ground. The hoisting cables are connected to a common hoisting engine. The entire assembly of panels can be raised in unison about the structure for daily activities and then lowered at night or quickly lowered in the event of high winds.
