Принадлежит:

Various embodiments of the present disclosure provide a portable dunnage bag inflator that provides a compact, pressurized source of air and that is easily mounted onto a movable cargo mover (such as a forklift truck or a pallet jack). Generally, the portable dunnage bag inflator includes an impellor-driven blower that, in operation, draws air at atmospheric pressure through an air intake grid or air inlet into the impellor and expels the air through an inflation hose. Since the portable dunnage bag inflator includes an impellor-driven blower, the pressure of the expelled air is higher than atmospheric pressure. This enables dunnage bags to be inflated to the desired specifications at point-of-use (e.g., during or after loading of cargo into a cargo container) and eliminates the need for a compressed air supply. 1. A portable dunnage bag inflator comprising:(a) a pressurized air generator defining one or more air inlet openings and an air outlet, the pressurized air generator configured to draw air at a first pressure through the one or more air inlet openings into the pressurized air generator and expel the air at a second higher pressure through the air outlet;(b) a cargo mover mounting bracket attached to the pressurized air generator and configured to attach to a frame of a cargo mover; and(c) an inflation hose assembly fluidly connected to the air outlet of the pressurized air generator.2.
