How often should the tower crane be inspected?

The recommended practice for tower crane inspections emphasizes the importance of daily checks before use, along with regular inspections in accordance with regulatory requirements. Daily inspections are crucial because they allow operators to identify any immediate safety concerns or mechanical issues that could affect the crane's operation. These checks typically include examining the crane's operational functionality, the condition of various parts, and ensuring that safety devices are working properly.

In addition to daily inspections, adhering to regulatory requirements for more comprehensive inspections ensures compliance with safety standards and helps prevent accidents. Regulatory bodies often specify how frequently more detailed inspections should occur, which may include more thorough assessments that look at components and systems in greater depth than a daily check.

While other answer choices suggest some level of inspection frequency, they do not encompass the comprehensive approach needed for safe tower crane operation. Regular and frequent inspections are crucial in maintaining safety standards on construction sites where tower cranes operate.
