What is the primary function of screwjacks in scaffolding?

The primary function of screwjacks in scaffolding is to level the scaffold. This is crucial for ensuring the stability and safety of the scaffold structure. Screwjacks allow for precise adjustments to be made to the height of each individual leg of the scaffold. By turning the screw mechanism, workers can raise or lower sections of the scaffold, making it possible to achieve a level platform even on uneven ground.

Leveling is essential not only for safety but also for ensuring that workers can operate effectively and that materials can be placed and moved safely on the scaffold. If the scaffold is not level, it can lead to problems such as instability or excessive sway, which could pose risks to workers and equipment.

While screwjacks do assist in supporting the overall weight of the scaffold, their primary role focuses specifically on leveling. Similarly, securing the scaffold to the ground and providing additional height are functions related to scaffold assembly and design but are not the main purpose of screwjacks.
