The flexible transmission column device has the following main characteristics:

1) Convert the horizontal movement of the column joint into vertical movement through a transmission box to achieve vertical lifting.

2) Transform the soft column sections into column sections with unidirectional stiffness, and connect the rigid column sections with movable hinges to form a vertical rigid column that can withstand vertical loads.

3) Smooth operation, strong reliability, long service life, low maintenance cost, high repeatability positioning accuracy, flexible configuration, easy installation, suitable for heavy loads (maximum dynamic load of a single flexible transmission column is 60 tons, static load is over 90 tons), shallow foundation pits with large stroke (maximum stroke can reach 16m or more).
