An ideal tool to easily pick up and move a machine, seating stand module or other heavy object on air casters. If the machine is only accessible from one side, this module can easily be slid underneath. Each Air Beam, also known as an Air Plank, consists of two caster elements. The Air Beam can be adjusted as a whole or per caster element. At least two beams are required for a displacement. The beams are available in any length.
