What should be done when erecting scaffold on uneven surfaces?

When erecting scaffold on uneven surfaces, using screw jacks to level is the most effective and safest method. Screw jacks provide precise height adjustments to each leg of the scaffold, allowing it to be leveled accurately in conjunction with variations in terrain. This is essential for maintaining the stability and structural integrity of the scaffold, ensuring that it is safely supported on all sides.

Screw jacks allow for gradual adjustment, making it easier to compensate for minor discrepancies in ground height. When used appropriately, they help to create a stable work platform, reducing the risk of tipping or shifting that can occur if the scaffold is not level. Furthermore, the design of screw jacks makes them suitable for scaffolding applications, meeting safety regulations and industry standards.

While other methods might be considered, they do not provide the same level of security or precision. For example, using wooden blocks can be unreliable as they can shift, settle, or degrade, compromising the stability of the scaffold. Hydraulic lifts typically serve different purposes and are not ideal for leveling scaffolds directly on uneven ground. Securing with ropes might be necessary for additional support or stability, but it does not address the fundamental need for leveling the scaffold itself. Thus, using screw jacks is the most appropriate choice
