The aluminium Industrial triple extension ladders are specifically designed to withstand every day usage in a heavy duty site environment. They are kitemarked to the new EN131 Professional which is the highest duty rating for extension ladders in the UK and have a safe working load of 150kg.

The heavy duty stiles are of thick, box-section alloy which is graded in size according to the ladder length are wider and much more durable than what you would see on a trade or domestic extension ladder.  The ladder hooks help towards providing a smooth operation when pushing and retracting the extension ladder. They also come fitted solid rubber moulded feet which offers the ladder extra stability against slippages while the D shaped rungs give the user as much comfort as possible while they are conducting their work at height.

 These extension ladders are the ideal choice when working on constructions sites and in many instances you will find that the heath and safety officers will insist on using the new EN131 standard which has now replaced class 1 rated extension ladders.

How to use a triple extension ladder safely

Here are some rules for using a triple extension ladder safely. Some of these rules are specifically for triple extension ladders, others are basic principles that can be applied to ladder safety in general.

  • Inspect the ladder before use to ensure that it is not broken or faulty
  • Ensure that your sections are locked and secured before you start climbing
  • Maintain three points of contact and a firm grip at all times
  • Do not use near a powerline
  • Dress appropriately (e.g., suitable footwear, no long skirts or baggy clothes that will snag)
  • Check the surrounding area for hazards (e.g., traffic, pedestrians)
  • Ensure all 4 corners of the ladder are making firm contact, and that the ladder is propped up at a safe angle.
