Telescopic ladders are worthy of replacing traditional ladders in many ways. In addition to being relatively light, these ladders are compact, durable and versatile, and can provide you with a wide range of services at no additional cost. However, telescopic ladders are as easily damaged as any other equipment, especially when they are mishandled, poorly maintained, or used for the wrong purpose. It is very important to understand the most common failures that may exist with telescopic ladders. This acquaintance will help you avoid the situation that caused the failure, or know how to fix it when it happens. The following are common failures of telescopic ladders.
The foldable rungs on the retractable ladder should move freely up and down the ladder when the ladder is extended and retracted. Sometimes this does not happen naturally, and when you try to unfold and fold the ladder, you may encounter some form of resistance. This is one of the most common failures in telescopic ladders, and it has two possible causes. One reason is the accumulation of excessive dirt. When too much dirt comes into contact with the telescopic ladder, it is likely to block the inside of the door lintel, making it difficult for the steps to move up and down. To solve this problem, you should spray the lintel of the ladder with silicone furniture polish. This will leave a thin wax coating on the surface, which should solve the problem.
This is another serious failure of a telescopic ladder. The locking mechanism remains in place when each step is fully deployed. A typical telescopic ladder has 32 locking mechanisms, only one of which fails, and the entire ladder is not safe to use. Before using a ladder, you should always check the ladder to make sure that each locking mechanism is working properly. This failure will not occur if you buy a high-quality telescopic ladder that meets the EN131 standard.
This applies to those telescopic ladders with removable stabilizer bases. The ladder may have malfunctions that affect its stability during use. Usually, this happens when you use the ladder at a fully deployed height. Similarly, if you buy a good-quality telescopic ladder from a reputable company, you may never encounter this failure unless the maximum load-bearing capacity of the ladder is exceeded.
This kind of malfunction mainly occurs on low-quality telescopic ladders. You will encounter some squeaking and erratic movements when using the ladder, especially when using it at a fully extended height. This failure is caused by long-term use of a telescopic ladder, which means it is more like a sign of wear and tear than a failure. If you encounter it on a new or recently purchased ladder, then this is definitely a mistake.
