How is base jack used in Scaffolding?

The scaffolding leveling jacks the scaffold tower when the tower legs are placed on surfaces of different elevations. It ensures all the legs will have (appx) equal bearing on the substrate(s) the tower rests upon.

Unless the scaffolding screw jack is placed on something solid, it will need dunnage underneath it to properly transfer the leg load into the soil.

It is also used to ‘fine tune’ the height of the tower itself, so that height adjustments of up to around 12″ can be achieved.

Essentially, a scaffolding jack is a load bearing base and is used to hold standards/uprights (the vertical tubes) in place and help transfer the weight of the structure to the ground. The base jack is used to help spread the load and has a shank in the center to hold the tube in place. To eliminate sway, a facade brace is fitted to the face of the scaffold every 30 meters. The spacing of the upright scaffolding and base jack scaffolding is usually around every 2.1m but this can be reduced to 2m or 1.8m depending on the weight of the structure.
