Choosing the Right Castor Wheels

How To Inspect The Frames And Fasteners Of Castor Wheels

Castor wheels can only last long if the frames and fasteners that are holding them in place are well maintained. It is, therefore, necessary for you to turn the equipment on its side so that you can inspect the frames and fasteners of the castor wheels regularly. Pay special attention to the aspects highlighted in the discussion below during this periodic inspection.

Deck boards and welds

Examine any welds on the frames or fasteners of the castor wheels. You should also inspect the deck boards closely. Make sure that no visible damage, such as deteriorated welds, exists on these components of the equipment onto which castor wheels were installed. Replace any damaged or missing deck boards. Repair any welds that show signs of failing. Cracks or gaps within the weld seams are the most common warning signs of a failing weld joint.

Nuts and bolts

Next, pay attention to the nuts and bolts that are holding the castor wheels in place. Ensure that all the nuts and bolts are tightened to the appropriate level. Any loose component can cause the castor wheel to fail when it is carrying a load. Replace any missing nuts and bolts immediately.

Frame distortions

Another problem that you should look out for during the inspection exercise is distortion on the frame holding the castors. Impact loads and excessive loading can cause the frame to become distorted. Such distortions need to be fixed quickly before they can cause some of the castors to wear out prematurely as a result of having a bigger proportion of the load placed on them as a result of the frame distortion. However, some changes are allowed in case specialised castor wheels are used.

Lock-washers

Locknuts/lock-washers play an essential role in ensuring that castors stay in place during severe use conditions. For example, some models can deform to prevent a castor from being detached when an obstacle is hit at high speed. It is therefore crucial for you to check the locknuts during the inspection of the castors. Replace those that have signs of wear, such as cracks and extensive corrosion.

No amount of maintenance will prolong the life of castor wheels that are inappropriate for their application. You should investigate the suitability of the castor wheels on your equipment in case they keep failing. Ask an expert to observe your equipment in action who will recommend the changes that you need to make to receive prolonged service from your castor wheels.
