The Different Types of Ladder You Never Knew Existed
You might think that you have seen all the different types of ladder that exist in the world. After all, how many of them can there be? The following are some kinds of ladder that you have possibly never seen before.
Tactical / Assault Ladders
What kind of ladder do you think the army and special forces use on their missions? If you are picturing the sort of chunky wooden ladder that Blackadder and the gang used to climb out of the trenches in WWI then you are about a century out of date.
These days, tactical ladders or assault ladders are a lot more advanced. Many are made out of carbon fibre rods, meaning that they are very strong but also very lightweight and easy to store away. They also allow the user to climb it without making any noise.
You can choose assault ladders in different colours, to fit in with the environment where they are to be used as closely as possible. They are also designed so that each person can easily carry their own ladder by hand.
Why would a chicken need a ladder? The truth is that some people use this name for the type of ladder that is commonly used for working on roofs, with hooks that hold it firmly in place as you work. Other people call this a hook-over ladder.
The name seems to come from the fact that it is similar in some ways to the ladders used in chicken roosts. If you ever need to carry out work on a pitched roof then this is one of the safest ways of doing so.
The Pompier ladder has a similar sort of design. This is the model that is shaped like a question mark and is used by emergency services to scale buildings by hooking it into an open window before climbing up. It was invented by the German fire department in the mid-19th century.
You can probably easily picture someone standing on a ladder while they pick apples or pears off a tree. Yet, you might not be aware that a special ladder is used to do this. They are designed like tripods, with a supporting pole that makes it safe to use even on soft, uneven ground.
The ladder section is flared at the bottom, too. All three of the feet should be firmly placed into the ground, while the tripod pole should be uphill if it is to be used on sloping ground.
In this case, we have ladders that go up and down again, to form a type of bridge in the middle. They are typically used as safety ladders in factories, where workers are working at height but where there are machines obstructing a traditional ladder.
They will often be custom-designed to reflect the exact space they need to fit into. In addition, they may be firmly screwed into the floor if permanent access is needed.
