When or where are lifting bags ?

  • When there is little space available. Lifting bags are thin. Dependable on the type they are only 5 to max. 25mm thick.
  • When the force needs to be equally divided on a surface area. Lifting bags are made of rubber and follow the form of the surface area, against which the force is exercised.
  • When huge forces are required. Force equals Area times Pressure (F = P x A). The maximum permissible air pressure for our lifting bags is, dependable on the type, between 1.5 Bar and 8 Bar. The area of a lifting bag can be theoretically as big as you want, because we also produce Specials.
