Lockable castors provide stability and safety by allowing you to lock wheels in place when needed. However, like any equipment, they can occasionally encounter issues that affect their functionality. In this blog, we’ll cover some common problems with lockable castors, along with troubleshooting tips to keep your wheels operating smoothly and safely.


1. Castors Not Locking Properly


One of the most common issues with lockable castors is when the locking mechanism fails to engage fully. This can occur due to dirt or debris obstructing the mechanism or from general wear and tear over time.



  • Troubleshooting Tips:

    • Clean the Mechanism: Regularly inspect and clean the locking mechanism to remove any dirt, dust, or debris that may be causing obstructions.
    • Inspect for Damage: Look for signs of wear or damage, particularly if the castors are used frequently. Replacing worn parts or the entire castor may be necessary if they no longer lock securely.

2. Difficulty Releasing the Lock


Sometimes, lockable castor wheels can become difficult to release, making it hard to move equipment when needed. This can happen if the locking mechanism has rusted or if the parts have become misaligned.


  • Troubleshooting Tips:

    • Lubricate the Mechanism: Use a lubricant designed for castor wheels to keep the locking parts moving smoothly. Avoid over-lubricating, as this can attract more dirt and dust.
    • Check for Rust or Corrosion: If you notice any rust, especially in outdoor or humid environments, apply a rust remover or replace the castor if the corrosion is severe.

3. Locking Mechanism Worn Out


Over time, the locking mechanism on lockable castors can wear out, especially if used under heavy loads or harsh conditions. This can result in a loose lock, making the castor wheels unstable.


  • Troubleshooting Tips:

    • Regular Maintenance: Check the locks periodically and perform preventative maintenance to extend the lifespan of the castors.
    • Replace Worn Components: If you notice any wear on specific components, like the brake pad or lever, it may be more cost-effective to replace just the worn part rather than the entire castor.

4. Castors Not Staying in Place When Locked


If you find that your lockable castor wheels are not staying in place even when locked, this may indicate a problem with the locking pins or the surface the castors are on.


  • Troubleshooting Tips:

    • Inspect the Surface: Check that the surface is level and free from oil or grease that may affect grip.
    • Examine the Locking Pins: Look at the pins to ensure they’re engaging fully. Bent or damaged pins can prevent the wheels from locking correctly, so consider replacement if necessary.


5. Unusual Noises When Locking or Releasing


If you notice strange noises, like grinding or squeaking, when locking or releasing the castors, it’s often a sign of friction or dirt build-up within the locking mechanism.


  • Troubleshooting Tips:

    • Clean and Lubricate: Disassemble the locking mechanism, if possible, clean all parts, and apply a small amount of lubricant to reduce friction.
    • Inspect for Misalignment: Misaligned parts can cause friction, so realigning any shifted components can help resolve the issue.

6. Lockable Castors Not Compatible with Load Requirements


Lockable castors that aren’t rated for the load they’re carrying can result in operational issues, including locks that fail under pressure. Overloading is a common reason for castor failure and can quickly wear out your equipment.


  • Troubleshooting Tips:

    • Check Weight Ratings: Ensure that the castors you’re using are designed to handle the load they’re carrying. If not, consider upgrading to castors with a higher weight capacity.
    • Distribute Weight Evenly: If possible, distribute weight more evenly across multiple castors to reduce strain on any single wheel.


Lockable castors are essential for many applications, providing stability and safety for various types of equipment. By addressing these common issues, you can keep your lockable castors in top condition, ensuring they remain reliable and safe for everyday use.
