Heavy Lifting Rubber Air bags for and Moving Huge Construction Objects
specification Of Heavy lift airbags
Heavy lifting airbags are the most tough pneumatic bags that are used to provide excellent land transport of various heavy & huge structures such as large vessels and heavy loads comparied with marine salvage airbags. They are more flexible and economical than traditional lifting methods like trolley without need of spillway construction.

Selection Of Heavy lift airbags
Diameter: Dia1.0m airbags are the commonly used for caisson moving, and for the smaller sized caissons, Dia0.8m airbags are ideal one.
Effective Length (Le): In principle ,the effective length(Le) could be the caisson width plus 0.5m.Usually if caisson width>20m,airbags can be arranged as two rows.
Operating Pressure of Airbags : Actual Bearing Capacity of Unit= Weight of Caisson (G)/Total length of airba
