1. Check the visible wear degree of the tire tread of the trolley casters. "Flat spots" on the wheelbarrow's tire surface can indicate the accumulation of foreign objects. Debris such as lint and wire may wrap around the wheels. Remove the bolts and nuts on the casters and clean them. Check whether the wheel bearing is damaged. If the parts are not damaged, you can reassemble it and continue to use it. If you often encounter the phenomenon that the wheel is entangled with debris, it is recommended to install an anti-tangle cover to avoid it.
2. Loose casters or stuck wheels can also cause "flat spots". Proper maintenance and inspection, especially checking the tightness of the bolts and the amount of lubricating oil, and replacing damaged swivel casters can enhance the rolling performance and rotation flexibility of the equipment. .
3. Severe damage or looseness of rubber tires may lead to unstable rolling, air leakage, abnormal load, base plate damage, etc. Timely replacement of damaged tires and bearings can reduce the cost loss caused by shutdown due to caster damage.
4. After inspecting the repaired wheel, make sure the bolts and nuts are tight and use lock washers or lock nuts on all bolts if possible. If the bolts are loose, tighten them immediately. If the wheels installed in the bracket are loose, the wheels will be damaged or unable to rotate.
5. Regular maintenance of casters can keep them running smoothly for a long time, which is a good way to improve usage efficiency.
