In a manufacturing or construction setting, a ladder is indispensable. There are those who appreciate the ability to get a little higher to work on some piece of equipment or for installing something above their reach. Many will rely on A frame ladders for this, however, the industrial extension ladders have a far higher and more secure reach in most applications.
In some cases, an A frame may be the better choice. This means that it can be used in the center of a space where there is nothing to lean against. The downside of this is that there is a safety limit on the height you can reach. The extension type will be able to accomplish tasks, at the perimeter of that space, where most of the ladder work occurs.
These types of ladders are the best choice when looking to get higher than about 12 to 15 feet. That is because of the safety concerns that must be considered when dealing with an A frame. You can not step higher than the second step from the top on these models. That leaves a lot of room that can not be used.
The first thing that is noticed about an extension ladder is its ability to get higher than any normal A frame type unit. Depending on the size of the ladder, from 10 to 12 foot, heights of between 30 and 36 feet are possible. There is a section or more of additional lengths, on rails, attached to the back of the unit. Some units will have two or more of these with an upper limit of three.
The basic ladders have a hand actuated system which has the operator pushing the additional section up by hand. When it is at the correct height, an arm or hook will rest on one of the original rungs, holding it in place. A more advanced system and the more expensive units will use a pulley or set of pulleys, located at the top. The rope will be pulled to move these sections, one at a time, up or allowing them a controlled fall back into place.
Many different types of material are used in the manufacturing of these units. Areas of use as well as weight and costs should be considered when thinking about the type of material. Aluminum is very popular as it is strong and lightweight. Wooden ones have outlived their usefulness, especially in outdoor applications. Fiberglass is considered the best material for this and for specific reasons.
Fiberglass will not conduct electricity. This is the only material electricians will use and many trades have followed suit with this as they all deal with electrical connections in many ways. The fiberglass ones are also very light and as strong as the aluminum ones. They do not corrode or rust and fair very well in outdoor activities, although storing them outside is still frowned upon.
Getting all of the best equipment to allow you to perform the tasks you need to on a day to day basis means at least one of these ladders. No manufacturing or commercial enterprise, certainly no construction company, can operate without having this ability. The ability to control your own climbing without the need for an expensive scissor lift or boom truck is a good feeling.
