What items are typically not listed in the frequent inspection checklist?

The frequent inspection checklist for tower cranes is designed to ensure that essential safety and operational components are regularly assessed for integrity and functionality. Hydraulic pumps and valves, while critical to the operation of the crane, are typically part of a less frequent, more detailed maintenance inspection rather than the routine frequent inspection checklist.

Frequent inspections focus more on components directly associated with the crane's ability to lift and move loads safely, such as ropes and cables, which are crucial for lifting operations, control levers that directly affect the crane’s maneuverability, and load-bearing structures, which are essential for the overall stability and safety of the crane during operations. These items are frequently checked to quickly identify any potential hazards that could compromise safety. In contrast, hydraulic components may not require as frequent inspections because their failure may not immediately affect the lifting operation unless there is a significant leak or system failure. Therefore, they are addressed in scheduled maintenance rather than daily or routine checks.
