Regular gear case inspections are a key part of maintaining bridge cranes. These inspections help prevent gear-related issues and are necessary for both new and older cranes. Hoisting gears in older cranes can be a concern since many of them don’t meet today’s standards. Older gears may not be built as well, making them more likely to wear down or fail over time. In many cases, older cranes may not be equipped to handle their current workload, and a gear case inspection can identify this problem.
Gear Case Inspections Can Spot Needed Upgrades
Sometimes, after inspecting the gear case, you may find that a bridge crane needs upgrades due to outdated gears. Many older cranes were designed for lighter workloads, but production demands may have increased without upgrading the crane’s components. A gear case inspection can catch these issues early, helping prevent breakdowns or potential worker injuries. This kind of inspection is especially useful for spotting problems before they become serious.
Gear Case Inspections Are Thorough
A gear case inspection is detailed and goes beyond the regular daily or weekly checks. It includes inspecting all the components of the gear case, focusing on parts that are not usually looked at during routine maintenance. The inspection often involves reviewing the crane’s maintenance history, checking oil levels, inspecting the gear case mountings, and using tools like an endoscope to examine the bearings, shafts, and gear wheels. While this process may take time, it can help catch small issues before they turn into costly repairs.
Advanced Inspections May Be Needed
If a regular gear case inspection finds any problems, a more advanced inspection may be required. This involves fully disassembling the gear case and inspecting each part in detail. Parts that are damaged or worn out can be replaced during this inspection. It’s important to have replacement parts and a skilled mechanic ready to make these repairs. Techniques like magnetic rubber or dye penetrant testing may be used to examine the gears and shafts, and seals, bearings, and lubricants can also be replaced during this process.
