Ladders, platforms, and scaffolding provide elevated access to reach areas above the ground. Step stools reach low-level heights. Ladders provide a way to ascend and descend from varying heights. Stairs are inclined pathways that provide access from one level to another. Work platforms raise personnel to optimal working heights. Configurable platform systems are modular walkways that provide safe passage over obstacles. Stages support multiple people and equipment for activities such as speeches and ceremonies. Scaffolding is a temporary structure that provides a working space for personnel to stand on and hold their equipment. Personnel lifts are motor-powered or manually powered machines that raise workers to various heights.
