Getting up higher than a person can reach standing on their own feet is something that needs to happen a good portion of the time. There are many reasons for this and some of the ways people devise to accomplish this are not safe. Ladders come in all sorts and sizes and the one that is used the most, in commercial applications of all kinds, are industrial extension ladders.
The A frame ladder is very useful, however, it can not reach some heights needed, safely. It can also not expand and contract to meet different needs. The extension ladder comes in many sizes and materials and some will also contort into various other configurations if needed.
This type of equipment is manufactured using materials such as wood, aluminum and fiberglass. The wood ones are the heaviest, least expensive and, if not maintained properly, will break, mold and rot. Many people like the idea of a natural material for all of their equipment and take care of them for years of use. Many of these are painted various colors to protect them from outside weather conditions.
One of the more popular materials for this necessary piece of equipment is aluminum. It has the ability to be immune from rot and molds and can also be carried quite easily because of its light weight. It is as strong as steel and makes for a general purpose ladder where electricity is not concerned.
Fiberglass is a strong material with many of the characteristics of aluminum in that it is fairly light weight. Many of these are made from recycled materials so the naturalists among people will feel better about it. It can be painted, however, since the color is throughout the material it really is not necessary. This is a very popular type of ladder for the vast majority of commercial building trade professionals.
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.
What makes an extension ladder extend is the system of pulleys that is incorporated at the top of the ladder. With this system in place, the operator can pull the rope, through the pulley, to bring the other section of ladder up. This other section has arms that swing out and will rest on the rung that is closest to the height the professional needs. This holds the extension at that position until it is lifted off and raised or lowered.
For any task that needs that extra height, a ladder of this type is the best choice. Regardless of the material, this kind of ladder provides the flexibility that most tasks need. A standard A frame ladder is handy when doing little projects in the middle of the room. The extension ladder is for all others, especially the taller ones.
