DETERMINING CRANE INSPECTION FREQUENCY
When you use the proper inspection and maintenance frequency for your overhead cranes and hoists, you can increase operational efficiency, lower overall repair costs, and improve equipment safety.
The big question is: How do you determine crane inspection frequency?
Every business must prioritise worker safety, so it is essential to determine Crane Inspection Frequency, also minimum frequency of inspections must ensure that equipment conditions are checked frequently enough to ensure safety. Beyond worker protection, if the cranes are always secured, you reduce contractor liability and future enforcement issues.
The value of equipment maintenance costs and efficiency varies from one company to the next. Out of operation crane equipment will cost some companies tens of thousands of dollars per hour in lost production time, while it is just a small inconvenience for others. Inspections that detect flaws and allow for planned repairs will save money in a 'production-critical' company by reducing or eliminating crane-related unplanned downtime. Hence, it is very important to determine crane inscpection frequency.
A good crane and hoist inspection programme begins with well-trained and certified inspectors spending enough time inspecting all of the equipment components that may be defective and lead to a potential safety incident or unplanned breakdown.
When determining crane inspection frequency, great inspectors aren't enough; you also need to put in place a 'Frequent' and 'Periodic' inspection schedule that is frequent enough to spot issues before they become a safety or production issue. As a result, it's important to know the facility's equipment and the factors that influence the need for more or less regular maintenance.
Those factors are:
- The equipment's proclivity to break: This aspect is strongly affected by the equipment's age, maintenance history, and current condition.
- Grabs or lifters are used. These cranes are constantly loaded and subjected to wear.
- The frequency of use: Equipment that is used constantly for three shifts a day can be subjected to much more wear and tear. Cranes that are lifting at or near capacity are putting in more effort.
- Equipment in a hostile climate, such as one with extreme heat, moisture, cold, dust, or chemical contamination, will experience increased stress and corrosion of structural, mechanical, and electrical components.
- Operator training: Inadequately trained operators are more likely to jog the motion and violate conservative operating procedures, putting more stress on the machinery.
One of the best ways to determine the efficacy of crane inspection frequency is to look at the number and magnitude of protection and operational flaws that appear between the previous ‘Periodic’ crane inspection and the most recent. Suppose your cranes each have more than two or more within a given period. In that case, we suggest shortening the ‘Periodic’ inspection cycle so that you only have one newly discovered severe deficiency on average in the interim.
Examine the crane and hoist operation manuals and make a note of the recommended service and repair cycles. For both protection and liability reasons, never raise the intervals beyond what the manufacturer specifies.
In order to check the state of mechanical, electrical, and structural components of the crane and hoist during a Periodic Inspection, the Inspector must use a lift or the crane walkway to gain access to the equipment. Control panels are opened, and mechanical components such as drums, wheels, sheaves, and couplings are inspected for wear, breaks are adjusted, and gearboxes are tested for oil level.
The advantage of adequate crane and hoist inspections is that the expense is minimal as compared to the benefits of improved protection and reduced unplanned downtime costs. As a result, more is better. According to our research, businesses that conduct ‘Periodic’ checks and hence having an efficient crane inspection frequency on a monthly basis have the fewest safety issues and breakdowns.
