ABSTRACT:
An air blast device for removing moisture, snow, sleet and the like from the top surfaces of cargo containers. The device is usable with a substantially conventional container lifting device having a frame with extendable and contractable spreader arms. When lifting a container, the frame is disposed in close proximity above the top surface of the container, and detachably connected thereto. Three hollow air blast members are arranged on the frame extending the entire length thereof adjacent the top surface of the container. Two outermost air blast members are movable with the spreader arms of the frame. Each air blast member contains an air discharge opening through the lower portion thereof adjacent the top surface of the container. When air is supplied to the air blast members from an external air supply under the control of the operator, a blast of air is directed from the discharge openings over and against substantially the entire top surface of the container to remove moisture, snow, sleet, ice and the like therefrom.
