Ladders that can be extended
Extension ladders
Among the most commonly used tools by technicians and tradesmen is the extension ladder. Due to its popularity, it is also responsible for many of the work-related accidents that occur every year. Although extensions can be dangerous if used incorrectly, many of the incidents that occur each year can be prevented if they are used correctly.
Why use an extension ladder
Extension ladders are an incredibly useful, practical, and efficient tool. An extension is the most efficient and effective way to work at height. Extensions can be erected, scaled, and used at height in minutes because they can be extended many times their original length. Alternatives, such as scaffold towers and cherry picker cranes, would either be too expensive, too time-consuming to erect or both.
When to use an Extension Ladder
Not every job that requires working at height needs an extension ladder. Often, when working at low height a step-ladder will suffice. A roof ladder can often be used for working down to a height as well, so keep this in mind when you're choosing ladders.
How to use an Extension Ladder
There are five steps to using extension ladders safely:
Inspect - the ladder should be inspected all over for bends, cracks, buckling, or any other faults. Particular attention should be paid to the rungs and bottom feet. Pay attention to the area you are working on as well. Make sure it is flat and even. It should also be free from loose gravel stones or dirt. Make sure there is room to work in too.
Erect - extend the ladder as required. Don't overextend; there should be a block that prevents you from going too high. If there is not, ensure you leave several rungs for safety. When erecting against the wall ensure you have a good angle. Too steep and the ladder could topple; too shallow it could slip.
Footing - If possible, get someone to foot the ladder. Ensure the ladder's feet are level and the ladder will not topple.
Climbing - keep three points of contact as you climb up. Tools should be in a belt or hauled up afterward, never climb with your hands full.
Working - Make sure you don't work too high. Make sure there are three rungs ahead of you for and holds. If necessary, secure tools rather than reach out. Work calmly, don't make any sudden or violent movements that could cause the ladder to sway.
A Few Specifications of the Three Section Extension Ladder
This ladder has a closed height of 3.3 meters and an extended height of 8.5 meters. It has 11 rungs and weighs 19kg. How to know if the ladder is the right height? Well, you need to consider what's called the working height. This is defined as the height that can be comfortably and safely reached when on the ladder and extending your arm. For example, a typical person about 5'6" tall with a vertical reach of about 12 inches can safely reach a height of 19 feet on a 20-foot extension ladder.
