Air film device can also be called as air pallet device. Air pallets are able to move heavy loads from just 500 pounds to 20 tons and beyond are available in many width sizes. They are designed to allow one person to move those heavy loads safely and efficiently. It has many manufacturing applications. It is used to enable precision positioning of heavy loads. Besides moving heavy bulky loads such as paper rolls, steel drums or other concentrated loads in warehousing and manufacturing applications, they are also ideal for transporting load in clean room environments moving finished products to shipping and storage areas, precisely aligning machines over footings, moving modules, and rearranging entire production lines. It can be used in the place of cranes and hoists. A thin film of compressed air is used to float loads of up to 300,000 lbs. so that a horizontal push of 1 lb. can move 1000 lb. load; floating action enables load to rotate or translate in any direction in the horizontal plane. It requires a smooth floor surface against which air streams underneath the device can push. It can be used in warehousing as the mechanism to convert stationary racks into sliding racks.
