Common Faults In Telescopic Ladders
Telescopic ladders are worthy replacements for the traditional ladders in many aspects. Other than being relatively light, these ladders are compact, durable and multipurpose, giving you a wide range of services at no extra cost. Nevertheless, telescopic ladders, just like any other piece of equipment are prone to damages especially when mishandled, poorly maintained or used for the wrong purpose. It is important that you acquaint yourself with the most common faults that telescopic ladders can have. This acquaintance will either help you avoid those circumstances that cause the faults or know how to fix them when they occur. Here are the common faults in telescopic ladders.
Stiff Up And Down Mechanism
The collapsible rungs on an extendable ladder are supposed to move freely up and down the stiles when extending and retracting the ladder. Sometimes this does not happen naturally and you might encounter some form of resistance when you try 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 too much dirt gets into contact with the telescopic ladder, chances are that it will clog the inside of the stiles making it difficult to move the rungs up and down. To solve this problem, you should use a silicone-based furniture polish to spray the stiles of the ladder. This will leave a thin wax coating on the surface which should solve the problem.The other cause of the stiff up and down movement of the rungs is if you attempt to lubricate the ladder using a WD40 lubricant.
Faulty Locking Mechanism
This is another serious fault in a telescopic ladder. The lock mechanism holds each rung in position when fully extended. A typical telescopic ladder has 32 locking mechanisms and just one of them getting faulty renders the whole ladder unsafe for use. You should always check your ladder to ensure that each of the locking mechanisms is functional before using it. You will not experience this kind of fault if you buy a high-quality telescopic ladder that complies with EN131 standards.
This applies to those telescopic ladders that come with a detachable stabilizer base. A fault may occur affecting the stability of the ladder when in use. More often than not, this happens when you use the ladder in its fully extended height. Again, if you get yourself a good quality telescopic ladder from a reputable company, you are likely to never experience this kind of fault unless you exceed the ladder’s maximum weight capacity.
Shaky Telescopic Ladder
This fault occurs mostly in low quality telescopic ladders whereby you experience some squeaks and wavering movements with the ladder, especially when using it in its fully extended height. This fault results from long-term use of a telescopic ladder, which means it is more of a sign of wear and tear than a fault. If you experience it in a new or recently bought ladder, then it is definitely a fault.
