Telescopic ladders have become one of the most popular tools for homeowners, contractors, electricians, and outdoor users. Their lightweight structure, compact size, and adjustable height make them a smart alternative to traditional ladders.
However, many users do not know how to properly maintain or operate a telescopic ladder, which leads to common issues such as jamming, bending, or malfunctioning locks.

In this guide, we will explain the most common problems of telescopic ladders and show you how to avoid them to ensure maximum safety and durability.

1. Ladder Sections Get Stuck or Fail to Retract Smoothly

Why It Happens

• Dust, sand, paint, or oil stains get into the inner tubes

• Lack of regular cleaning

• Forceful extension or retraction

• Using the ladder in humid or sandy environments

How to Avoid It

• Wipe the ladder tubes with a dry cloth after every use

• Avoid using lubricants—oil attracts dust and makes it worse

• Do not pull or slam sections too hard

• Store the ladder in a dry place, away from construction dust

---

2. Locking Mechanisms Don’t Engage Properly

Why It Happens

• Internal lock wear from long-term use

• Poor-quality plastic locking buttons

• Pulling two sections at once

• Misalignment from uneven extension

How to Avoid It

• Extend the ladder slowly, one step at a time

• Listen for the “click” sound of each lock engaging

• Never climb if any lock is not fully engaged

• Choose ladders with thick aluminum tubes and reinforced locking systems

---

3. Ladder Bends Under Heavy Load

Why It Happens

• Overloading beyond weight capacity

• Thin aluminum tubes used by low-quality manufacturers

• Incorrect climbing angle

• Using the ladder on uneven or soft ground

How to Avoid It

• Purchase ladders with EN131 certification

• Never exceed the listed weight limit

• Position the ladder at a 75-degree angle

• Use anti-slip feet on solid and flat ground

---

4. Hand Pinching During Retraction

Why It Happens

• Rapid free-fall retraction

• Cheap ladders without slow-down technology

• Hands placed between sections

How to Avoid It

• Keep your hands on the outside of the ladder frame

• Choose ladders with air-damping / slow retraction system

• Retract the ladder from the top down, not bottom up

• Do not allow children to handle the ladder

---

5. Ladder Becomes Wobbly or Unstable During Use

Why It Happens

• Worn or broken anti-slip rubber feet

• Extended too high without stability support

• Surface is slippery or uneven

• Side loading instead of climbing straight up

How to Avoid It

• Check the rubber feet regularly

• Replace damaged feet immediately

• Always climb facing the ladder, not sideways

• If working at high height, use an A-frame telescopic ladder for stability

---

6. Corrosion or Surface Damage on Aluminum Tubes

Why It Happens

• Exposure to rain, humidity, or chemicals

• Scratches that break the protective oxide layer

• Saltwater environments (common in coastal regions)

How to Avoid It

• Wipe the ladder dry before storage

• Avoid leaving it outdoors overnight

• Choose high-grade aluminum alloy such as 6063-T5

• Use protective storage bags for long-term storage

How to Keep Your Telescopic Ladder in Excellent Condition

To maximize safety and extend the lifespan of your ladder, follow these simple rules:

• Inspect your ladder before each use

• Clean the tubes weekly if used frequently

• Avoid overextending or slamming the steps

• Use the right ladder size for the task

• Buy from trusted manufacturers with long-term production experience

With proper care, a high-quality telescopic ladder can last many years without issues.

Why Choosing a High-Quality Ladder Matters

Most problems happen because of poor-quality ladders using:

• Thin aluminum

• Cheap plastic locks

• Low-cost internal mechanisms

• No safety certifications

A professionally manufactured telescopic ladder with EN131, ANSI or CE standards will significantly reduce risks.
