Abstract
A cradle for supporting and installing a rolled curtain door comprises rollers configured to support, and permit rolling, of a rolled curtain door thereon. Extensions with rollers permit the cradle to support rolled curtain doors of varying length. A motor may be connected to the rollers to assist in rotating the door. The cradle may be mounted on the tines of a fork on a lifting device. A lift assembly having a tower and base may be attached to the cradle for manually positioning, and mechanically elevating the cradle and door when installing the door. The tower is extended by a piston-and-cylinder unit. A winch motor and cable, or a boom hoist attached to the tower may be used to load a door onto the cradle.
