Functional inspections are performed daily by the single girder overhead crane operator. Inspection intervals depend on the criticality of the component as well as the degree of wear and tear.
Inspection intervals depend on the criticality of the component, the degree of wear and tear, failure or degradation. A qualified inspection specialist can help determine the inspection interval based on the component, duty cycle and manufacturer recommendations.
The main factor in determining the cost of a single girder overhead crane inspection is the frequency or type of crane inspections performed. Knowing how often inspections are required is the first step in determining the inspection criteria and frequency. Having an inspection plan that meets the requirements of OSHA, ASME and CMAA standards will help you comply with inspection regulations.
Does production need to be stopped during the inspection?
The simple answer is: not necessarily.
If you have an industrial overhead crane servicing a production line, then that line will certainly be affected as the inspection may last for several hours. However, if you have multiple overhead cranes in different bays, then the rest of the facility can certainly continue to operate.
If there are multiple industrial overhead cranes on the same track and the inspector is able to isolate one for inspection, then the other crane can certainly be running to maintain production. Doing so will require the inspector to take precautions to protect himself from the other crane still operating on that track.
How long does a monorail overhead crane need to be down for inspection?
There are many different variables that determine how long it will take to perform an inspection.
It really depends on the complexity of the monorail overhead crane. A top running single girder overhead crane with a load capacity of 1-20 tons will certainly take less time to inspect than a double girder overhead crane. The biggest determinant of downtime is the number of components that need to be inspected.
