ANALYSIS OF LAUNCHING OF STEEL GIRDER USING CRANE FOR RAIL OVER BRIDGE

Abstract

The construction of Rail Over Bridges (ROBs) has emerged as a crucial solution to reduce traffic congestion and ensure smooth connectivity by eliminating level crossings. A vital phase in ROB construction is the launching of steel girders, which requires precise planning, technical expertise, and adherence to safety standards. Among the available techniques, crane-assisted launching has gained prominence due to its adaptability to constrained urban environments, flexibility in handling heavy components, and reduced dependency on permanent launching equipment. This synopsis emphasizes the methodology and practical aspects of launching steel girders using cranes. It covers the major structural components involved, outlines the Jaiswar Ashok Kumar Ramchandra Suryamati, Manisha Jamgade, Raju Narwade https://iaeme.com/Home/journal/IJCIET 2 editor@iaeme.com step-by-step erection procedure, and highlights the critical role of safety measures during operations. The discussion also addresses the challenges faced in real-world projects, such as restricted working spaces, live railway traffic, and night-block constraints, bridging the gap between theoretical structural design and field-level execution. The study aims to improve understanding of crane-based girder launching by: • Analyzing structural and procedural elements involved. • Documenting step-by-step erection methodology. • Identifying safety protocols before and during launching. • Reviewing current limitations in practical implementation. • Suggesting improvements for future construction practices This work contributes toward better integration of theoretical optimization with practical execution, offering insights to improve construction methodologies. The findings aim to support engineers and project managers in achieving safer, more efficient, and cost-effective ROB construction through the effective use of cranes for steel girder launching.
