Aerial devices are equipment designed to lift people or materials to elevated heights. Common examples include scissor lifts, boom lifts, and aerial work platforms. These devices are often used in construction, maintenance, and other industries where working at heights is necessary. Typically powered by electricity or diesel, aerial devices come in various sizes and configurations to suit different tasks. Safety features, such as guardrails and harness attachment points, are essential to protect operators. Proper training and adherence to safety regulations are crucial when using these machines to prevent accidents and ensure efficient operation.
