Telescopic ladders are incredibly versatile — but also easy to misuse if you’re not familiar with how they work. Unlike traditional ladders, they include moving parts and locking systems that need proper care and correct usage.

Here are the top mistakes professionals (and even experienced tradespeople) still make — and how to avoid them:

Mistake 1: Using It Horizontally as a Plank

Why it’s dangerous: Telescopic ladders are designed for vertical load-bearing only. When used horizontally (e.g. bridging between platforms), the structural integrity is compromised — the rungs and locking pins are not rated for this.

What to do instead: Use the correct bridging or platform equipment. Never treat a ladder like scaffolding.

Mistake 2: Storing It Wet, Dirty, or Partially Extended

Why it matters: Water, dust, plaster, and grit can build up inside the tubes, blocking the locking mechanisms or causing corrosion. Storing it partially extended weakens alignment over time.

Fix it: Always clean and dry your ladder before storage. Fully retract and store in a clean, dry, upright position — ideally indoors.

Mistake 3: Using It as a Vertical Descent (Fire Escape/RESQ Style)

The issue: Telescopic ladders should never be opened vertically downward — the locking pins are not designed to hold the weight in reverse. This creates a serious fall risk.

Remember: Always extend telescopic ladders upright from the ground up. Never flip or reverse their intended use.

Mistake 4: Applying the Wrong Lubricants

Why this is a problem: Using WD40 or grease-based lubricants attracts dust and dirt, which can clog internal parts and cause sticking.

Use this instead: If your user manual allows it, apply a silicone-based furniture polish lightly to the stiles — not to the rungs or locking pins.

Mistake 5: Not Checking Locking Indicators Before Climbing

Common oversight: Users sometimes skip checking if each rung has locked into place. One missed lock could lead to sudden collapse during use.

Make it a habit: Always confirm that green lock indicators are fully engaged on each rung before stepping on.

Avoidable. Preventable. Professional.

These are simple checks — but ignoring them shortens your ladder’s life and risks operator safety. Preventing misuse is part of your duty of care on any jobsite.
