Industrial Extension Ladders Come In Many Styles And Materials

By Luisa Sharpe


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.

Unlike the A frame type ladder, an extension ladder must have something on which to lean for support. Unlike the A frame, this ladder can be made smaller and larger with the use of the extending piece. These ladders come in a number of sizes, materials and configuration for maximum adaptability to just about any job.

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.

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.

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.

Fiberglass is the choice of materials for most construction companies and all electricians. This is because fiberglass does not conduct electricity. When working with this dangerous source of energy, it is necessary to prevent damage to people and other things by insulating them from this. This type of ladder can also be painted, however, with nothing to rust or corrode, the dangers of using a paint that may be conducive to electrical charges should be avoided.

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.

A frames are handy when there is a need for a little height. The extension ladder is available for heights above that and can have safety tie offs for various purposes. Since you should not step on the top two rungs of the average A frame, there is a lot wasted height. These will come in two or three section units with additional sections if needed.
