Working at heights is very dangerous. When it comes to building larger structures, builders cope by erecting a massive scaffold. Professional scaffolding allows them to move safely around or inside the building under construction. The structure also makes it easier for them to transport building materials and tools to higher levels, thanks to the use of various types of cranes and booms. However, repairing a tall electricity pole or a minor fault on a building does not require erecting a huge scaffold. Then the use of a professional hoist is sufficient.
