SUMMARY

The braking mechanism used in airport shopping trolleys is primarily a lever system that operates through friction. When the handle is pulled, a rubber-coated steel bar or a rod-operated brake clamps the wheel, similar to bicycle brakes. This system is designed to be straightforward, providing an on/off braking action rather than progressive control. Service carts on planes utilize a similar lever-type brake system, where one lever locks the brake and another releases it.

PREREQUISITES
  • Understanding of basic mechanical systems
  • Familiarity with friction-based braking mechanisms
  • Knowledge of lever systems and their applications
  • Insight into materials used in braking systems, such as rubber and steel
NEXT STEPS
  • Research the design and functionality of lever brake systems in various applications
  • Explore the materials used in friction brakes and their performance characteristics
  • Investigate the differences between bicycle brakes and other simple braking mechanisms
  • Learn about the safety standards and regulations for airport equipment
USEFUL FOR

Engineers, product designers, and anyone involved in the design or maintenance of airport equipment and trolleys will benefit from this discussion.

Hi there.

What is the braking mechanism called used in trolleys/ especially in airport trolleys where you pull the handle to stop the wheels? And how does it work?

Cheers

I'm afraid that I've never seen one, so I don't know. It's unlikely, however, that they use anything exotic like calipers or brake drums. On 'walkers' for the elderly, or wheelchairs, it's generally just a rubber-coated steel bar that gets pulled against the tire.
 
A brake mechanism works by friction. If they have brakes, it may be a leaver system, much like a hand brake in a car. The service carts on planes have a lever type brake system. One lever is pressed to lock the brake on, and another lever is pressed to release the brake.
 
I have not seen what you are referring to. However, I would think that it would be something similar to what you see in a bicycle.
 
The ones I've seen are just a simple rod-operated brake which clamps the wheel from both sides by two circular rubber discs. You don't really need the progressive control you have with a car or a bike, they're pretty crude, clunky, and on/off.
