What is it with overhead cranes and downtime? It is hard to find an overhead crane that does not face downtime issues. However, how frequently these issues happen varies from one equipment to the other and from one brand to the other. If you want to address the overhead crane downtime you should first understand that several factors are at play. Only when you understand the dynamics involved here it is possible for you to manage these issues.
When you purchased your cranes, if all that you were concerned is the cost factor and if you failed to pay attention to the quality factor then you are more likely to be experiencing a higher rate of issues and more frequent downtime windows. Yes, definitely the overall quality of the EOT cranes will determine how well they perform and how frequently they run into issues. You need to therefore select the best cranes suppliers after careful review and screening.
What confuses people is that even after selecting the best cranes manufacturers in the country they run into maintenance issues with their cranes. How do you handle such situations? Where are things going wrong? There could be more than one issue here. For example, one may not have hired a qualified and trained crane operator to operate the equipment. When such a person operates the crane, then they are likely to make mistakes and damage the equipment. This is one of the most common causes for the frequent downtime issues with the cranes. Even after you resolve the issue with the crane, such episodes will recur until you change the crane operator.
Failing to set a clear protocol for usage will also result in frequent downtime issues. If your operator is careless and if they do not follow the best practices when using the crane then they could be pushing the equipment beyond its limits so speed up things. When you use your crane beyond its maximum capacity for whatever reasons, it is likely to breakdown or at least it will trigger the onset of the issues. As long as you are keeping to the safe limits your lifting equipment is likely to run without any glitches for much longer periods. Of course, there will be general wear and tear but it will not result in immediate breakdown.
In any manufacturing setup a single day of downtime, why for that matter, even a few hours of downtime could trigger huge monetary losses. You need to therefore keep your overhead cranes at optimal condition. Make no mistake in this regard and oversights here could turn out to be very expensive.
You should also plan to keep the EOT cranes well maintained. It should be possible for you to sign an AMC with your crane manufacturer so that they could regularly visit your factory to inspect your cranes and spot any issues that may be there well in advance and do the needful to resolve the situation before things aggravate.
