Abstract
The tower crane climbing process is one of the most hazardous operations due to its complexity and technical challenges, making it difficult to ensure both structural and worker safety. To address this issue, this study proposes a systematic control framework based on digital navigation. This framework integrates theoretical risk analysis, safety information requirements, and the practical implementation of a safety intelligent navigation platform (SINP). Key safety-critical points in the tower crane climbing process are identified through process analysis, and worker situation awareness requirements are derived using goal-directed task analysis (GDTA). The SINP is designed to digitally capture safety-related data, assess safety conditions intelligently, and provide automated safety guidance. The platform enables systematic control of tower crane safety through three key functions: (1) real-time navigation and alarms for workers via an edge intelligent control device (EICD); (2) synchronous monitoring and interaction for on-site supervisors using mobile devices; and (3) remote inspections for management through cloud-based platforms. Two experimental scenarios were conducted to simulate real-world engineering conditions and evaluate the framework's effectiveness. Results show a significant improvement in worker performance and process safety, which are attributed to the advantages of SINP, which include (1) timely and efficient information sharing; (2) accurate and orderly safety guidance; (3) real-time and effective alarms; and (4) positive psychological reinforcement for workers. This study introduces a proactive safety management approach that can prevent accidents at their source and enhance worker performance throughout the tower crane climbing process.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
