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

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.
