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.
One of the many reasons the A frame ladder has a limited useful range is because of the safety factors involved. By law a person can not step on the top platform and not even on the first step down. Other locations restrict a body from using the top two steps.
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.
Many extension ladders are set so that you will push the additional section up by hand. The correct height having been achieved, an arm will latch onto a rung and it will hold fast to it. Some of these ladders will have pulleys, attached to the top of the unit, with a rope for pulling the section up, latching it in the same way.
The type of material that these units are constructed of will also be an important factor to consider. Most of these are metal, such as aluminum and can be painted to signify their association with a certain area of the plant or site. There are wooden ones, although this has been discouraged in recent years especially for outdoor work. The most popular material for these is fiberglass for very specific reasons.
The material does not corrode or rust even a bit. It has the same strength, without the weight, of metal units and the most important feature is how it protects the climber from one thing. The fiberglass ladder does not conduct electricity so workers, moving in and around these connections, will not be subjected to electrocution dangers as much.
Having a task that requires you or your employees to get up high and with no budget for a scissor lift or boom truck, is all the reason you need to have a few of these ladders on hand. They are easy to move, set up and extend when needed. With the pulley system and special feet that can be attached for uneven ground, this is the way to safely handle all of your above ground level work.
