Enhancing Safety and Efficiency in Crane Operations: Addressing Communication Challenges and Blind Lifts

This study presents a methodology to improve safety and efficiency in crane operations, particularly addressing challenges in modular construction and complex lifts. It focuses on enhancing communication between crane operators and signalmen, especially in congested environments. Through a literature review, it highlights the need for innovative solutions in signalman location planning and communication methods. The proposed methodology involves preplanning and optimizing signalman visibility using a grid system to determine suitable standing locations. By assessing visibility in relation to lifting module corners, the study aims to ensure clear lines of sight for safe lifting. Validated through two case studies, the methodology demonstrates effectiveness in planning signalman locations for various lifting scenarios. This research offers a systematic approach to tackle crane operation challenges, improving safety, efficiency, and precision in construction projects. Further development and implementation of such methodologies are vital for the success of modular construction and heavy industrial projects.
