Verlängerungsleitern

Verlängerungsleitern, also known as extension ladders, are a type of portable ladder that can be extended to reach greater heights. They typically consist of two or more sections that slide telescopically into one another. This design allows for adjustable length, making them versatile for various tasks. The base section is usually wider than the upper sections for stability.

Extension ladders are commonly constructed from aluminum or fiberglass. Aluminum ladders are lightweight and corrosion-resistant, making them popular for general use. Fiberglass ladders offer superior electrical insulation, which is crucial for working near power lines or in environments where electrical hazards are present.

Operating an extension ladder involves carefully extending the sections to the desired length and ensuring they are securely locked in place. The ladder should be placed on a firm, level surface and leaned against a stable support at the correct angle, typically a 4:1 ratio (one unit out for every four units up). Safety features such as rung locks, non-slip feet, and guide rails are important considerations when choosing and using an extension ladder. They are widely used in construction, maintenance, and domestic applications where access to elevated areas is required.
