Scaffold towers come in a variety of designs and sizes. The usual length and width are 5 feet and 7 feet, respectively. Reaching a height of 5 feet all the way up to 30 feet, they can be used for large-scale projects. The maximum safe working height for a rolling scaffold is determined by several factors such as design, code requirements, material strength, type of foundation required, etc. Generally, rolling scaffolds can reach a height of 50 feet if the structure supporting it is stable enough. However, their use is restricted by many local authorities in areas with much snowfall due to the risk of collapse caused by weight of the scaffold itself or heavy materials being worked on. The maximum load that a scaffold can hold is based on its design and what kind of base it has. If it has a solid base, like concrete or stone, then the load limit will be based on the size of the scaffold. For example, a 7-foot wide x 25-foot long rolling scaffold weighing 2,000 pounds would meet the requirement of having a load capacity of 100,000 pounds. On the other hand, if it has a base of wood slats, the load limit will be based on how many slats make up the base.
