Airsled’s 9″ W x 28″ L air beams are designed specifically for narrow/slender loads where 36″ L air beams may be less optimal. Examples of loads when the 9×28 air beams are more suitable include credenzas, sideboard buffets/cabinets, bookshelves, and media consoles just to name a few. These loads tend to be less than 22″ deep and the 7×36 and 9×36 air beams, given their length relative to load depth, will bend upward at the ends during use. As the air beams bend, they perform less optimally. The 9×28 air beams will flex less and remain more rigid moving such narrow loads leading to better performance. The 9×28 air beams have a 450 lb. lift rating when used with a Light Duty Appliance Mover, 525 lb lift capacity when used with a Standard 2HP Appliance Mover, and a 650 lb lift capacity with used with a Heavy-Duty 4HP Appliance Mover.
