Abstract
Kegiatan maintenance Jembatan Raja Haji Fisabilillah memerlukan sistem lifting yang aman dan andal. Namun, sistem lifting eksisting mengalami korosi, deformasi pada lifter rail, serta belum dilengkapi perangkat keselamatan sekunder sesuai SNI EN 1808:2015. Penelitian ini bertujuan melakukan perancangan ulang dan analisis struktur sistem lifting menggunakan metode Finite Element Analysis (FEA) serta menghasilkan rekomendasi spesifikasi komponen sebagai acuan dalam proses manufaktur. Hasil simulasi menunjukkan bahwa desain eksisting menghasilkan Equivalent Stress sebesar 197,26 MPa, sedangkan desain hasil perancangan ulang tahap pertama sebesar 256,98 MPa sehingga belum memenuhi kriteria kekuatan material EN S235JR. Pengembangan desain melalui penambahan struktur pengaku dan perubahan ketebalan pelat menjadi 2 mm berhasil menurunkan Equivalent Stress menjadi 143,69 MPa dengan Total Deformation sebesar 1,892 mm, sehingga memenuhi kriteria kekuatan material. Berdasarkan hasil analisis, sistem lifting direkomendasikan menggunakan hook berkapasitas SWL 2 ton, wire rope Ø12 mm sepanjang 65 m, electric winch berkapasitas minimum 1 ton dengan daya motor minimum 1,5 kW, serta dilengkapi safety wire rope dan blockstop sebagai sistem pengaman sekunder. Hasil penelitian ini diharapkan menjadi acuan dalam proses manufaktur sistem lifting.

Bridge maintenance activities require a safe and reliable lifting system to provide access for maintenance personnel working at elevated locations. However, the existing lifting system has experienced corrosion, deformation of the lifter rail, and the absence of secondary safety devices in accordance with SNI EN 1808:2015. This study aims to redesign and analyze the structural performance of the lifting system using the Finite Element Analysis (FEA) method and to provide recommended component specifications as a reference for the manufacturing process. The simulation results show that the existing design produces a maximum Equivalent Stress of 197.26 MPa, while the first redesigned model produces 256.98 MPa, exceeding the yield strength of EN S235JR steel. Design improvements through the addition of reinforcing members and increasing the floor plate thickness to 2 mm successfully reduced the Equivalent Stress to 143.69 MPa with a maximum Total Deformation of 1.892 mm, indicating that the final design satisfies the material strength criteria. Based on the analysis results, the lifting system is recommended to use a 2-ton Safe Working Load (SWL) hook, a 12 mm diameter wire rope with a length of 65 m, an electric winch with a minimum lifting capacity of 1 ton and a minimum motor power of 1,5 kW, as well as a safety wire rope and blockstop as secondary safety devices. The results of this study are expected to serve as a reference for the manufacturing process of the lifting system
