Many activities can not be done from the ground or floor. A large portion of construction must be done on elevated platforms or with ladders of various sizes and shapes. Industrial extension ladders are part of this mix as they provide the height needed and the strength to withstand anyone and their tools.
One of the other types of ladder is the A frame. This is a popular type, however, it is not as safe, at great heights, as the extension ladder is. It also can not change heights to enable the same unit to be used for smaller projects and those requiring greater heights. The A frame ladder has its place but it can not do what the extension ladder can do and does not try.
Different materials are used to manufacture this type of ladder. Wood, fiberglass as well as aluminum are just a few of these. The heaviest ones are made from wood and they are also prone to rot, breaking and molds if stored improperly. Some people appreciate the natural materials being used and, as such, might be a good pick for them. They are also seen as being painted in various colors to help prevent weather getting to them.
General purpose extension ladders are made from aluminum. This is a light weight material that resists rust and corrosion. It is also largely immune from the effects of molds and rot. The ability of a large ladder to be carried, fairly easily, by one person, and the ability to carry it on the top of a car, truck or van makes this material generally acceptable.
A ladder that does not need painting is the fiberglass one. This is a light weight ladder and the color pigment is combined with the material that does not tear or crack. Most professional building trades use this as it can be as strong as steel and easy enough to carry and move around.
Electricians need fiberglass in their tools as it does not conduct electricity like aluminum or other metals do. Other trades, working around electrical connections, also need this protection as all professionals deal with the wiring even if only to move them for other tasks. Even wood ladders, when wet, will conduct this electricity and it is a dangerous element of construction for all concerned.
The system that makes these extension ladders what they are and what they can be is the pulleys that are attached to the top of the ladder. The section that will slide up and extend the reach can be accessed through this rope and those pulleys. By pulling down on this line, the section or extension, rises and can be slipped over one of the rungs. This fixes the length for a safe footing.
These ladders come in many styles and sizes. One of them is just right for you and the things you do. Many of them have wide bases for a sturdy footing and others have feet that will grip the ground even if slightly uneven ground. Having an A frame ladder is fine for some of the smaller tasks, however, when you are looking to get something done, an extension is what you reach for.
