Common faults in telescopic ladders


Telescopic ladders are version 2.0 of traditional ladders. In addition to being relatively light, these ladders are compact, durable and multipurpose, giving you a wide range of service possibilities. However, the stairs

Telescopic handpieces, like any work instrument, are prone to damage, especially when handled incorrectly, poorly maintained, or used for the wrong purpose. In we will help you avoid those circumstances that cause failures and know how to solve them. Here are the most common problems with telescopic ladders.

Rigid raising and lowering mechanism


The folding rungs of an extendable ladder are supposed to move freely up and down the stiles as the ladder is extended and retracted. Sometimes this does not occur naturally and you may encounter some form of resistance when trying to unfold and fold the ladder. This is one of the most common faults in telescopic ladders and it has two possible causes.


One of the causes is an excess accumulation of dirt. When there is too much dirt in contact with the telescopic ladder, it is likely to clog the inside of the stiles, making it difficult to move the rungs up and down. To solve this problem, you need to use a silicone-based furniture polish to spray the stair stiles. This will leave a thin layer of wax on the surface that should solve the problem.

The other cause of stiff up and down movement of the rungs is if you try to lubricate the ladder with a WD40 lubricant.

Faulty locking mechanism



This is another serious flaw in a telescopic ladder. The locking mechanism holds each rung in position when fully extended. A typical telescopic ladder has several locking mechanisms and if just one of them fails it makes the entire ladder unsafe for use. You should always check your ladder to make sure each of the locking mechanisms is working properly before using it. You will not experience this type of failure if you purchase a high quality telescopic ladder that meets EN131 standards.

Unstable base

This applies to telescopic ladders that come with a removable stabilizer base. A failure may occur that affects the stability of the ladder when in use. Most of the time, this happens when the ladder is used at its maximum extended height.

Unstable telescopic ladder


This fault mostly occurs on low-quality telescopic ladders, so you experience some squeaks and hesitant movements with the ladder, especially when used at its fully extended height. This failure is the result of long-term use of a telescopic ladder, which means it is more of a sign of wear and tear than failure. If you are experiencing it on a new or recently purchased ladder, then it is definitely a manufacturing error.
