When it comes to those tricky jobs which are just out of reach, a ladder is an essential tool. But, do you know how many injuries are caused each year through misuse of ladders, and bad ladder design? While some of those injuries are caused by human error, many are caused by poor materials and construction. For that reason, I recommend a heavy-duty ladder.

Not only is a heavy-duty step ladder sturdier and safer than a regular ladder, but it is also recommended for big people. A heavy-duty step ladder is designed to take a lot of weight while staying in place. You can also find heavy-duty step ladders, which are lightweight and multi-purpose.

What To Know Before Buying a Heavy-Duty Step Ladder

Types Of Step Ladders

This is the step ladder which you are most familiar with. It has steps on one side only, and the top shelf is not a step but can be used as a tool or material shelf. It can be sturdy and durable.

This step ladder has steps on both sides to allow two people to use it at once. Be sure to check the weight rating, though it is usually more than that of a standard ladder, allowing it to be used by heavier people.

This step ladder has steps on one side, like the standard ladder, but also has a platform on top which can be stood on. This is a great multi-functional ladder.

This step ladder has an A-frame design with steps on one side and an additional ladder which sticks up from the middle. It is a great multi-functional step ladder for working on ceilings.

This step ladder can be extended on either side. It has multiple configurations and is a true multi-purpose ladder. It is sturdy and great for working on stairs.

A tripod has steps on one side and only one rail on the other. It is designed to fit into places where other step ladders cannot.

Check The Load Capacity

Once you know what type of ladder you need, you should check the weight rating to make sure that you can use it safely. There is a ladder out there for every size and weight; it is just a matter of finding it. The load capacity is provided by the American National Standards Institute (ANSI).

  • Type III: 200 pounds (mainly used for home use)
  • Type II: 225 pounds
  • Type I: 250 pounds
  • Type IA: 300 pounds
  • Type IAA: 375 pounds

When you are deciding on which ladder to choose, be sure to factor in any clothing and tools which the user will also be wearing when using the ladder.

Fiberglass vs. Aluminum

Most ladder rails are crafted from either fiberglass or aluminum. Both of these two materials are sturdy, durable, and lightweight, but is there one which you should be choosing over the other?

The work you need to do will dictate which material is better. If you are doing any electrical work or working near to any live wires or electrical circuits, then a fiberglass ladder will work better as it will not conduct the electricity and shock you should you come into contact with anything.

An aluminum ladder is more lightweight than a fiberglass one and can hold more weight, making it better for bigger people. Being stronger, aluminum ladders also come in bigger sizes and can generally be extended more.

How To Match The Ladder To The Job

Buying the right step ladder is about a lot more than finding one which can hold your weight and is affordable; you should also be thinking about which ladder is going to be the safest and make your work the easiest.

It may seem obvious that a ladder which is too short is going to be dangerous in the workplace but did you know that a ladder which is too long is also going to slow you down and pose some danger too? You need to choose the ladder which is matched to the height of the job you are doing. However, it is not quite as simple as that.

When checking the height of the ladder, you need to remember that the total height of the ladder is not the same as the working height.

The height of the ladder does not take into account the highest point which you can stand on; it just tells you the total height.

Be sure to check where you can stand on the ladder and if that gives you enough elevation. One thing which you never want to do is to step higher than you should. The turns a sturdy step ladder into an unbalanced one.

Step Ladder Accessories

Some step ladders will come with additional accessories while some will be designed to be used with separately purchased accessories. When you are looking for additional safety or use, there are a few accessories which I recommend.

Stabilizers: These help to stabilize a ladder when it is against a surface and are also great for working around windows.

Level Kit: This allows you to extend the ladder on one side to find balance on uneven surfaces.

Ladder Jack: This allows two ladders to be able to support a scaffolding stage.
