Abstract

Penelitian bertujuan mengatasi masalah friction trolley wheel yang terjadi pada Rubber Tyred Gantry Crane (RTGC) tipe Konecranes di PT Terminal Petikemas Surabaya. Friction trolley wheel merupakan fenomena dimana trolley wheel bergerak tidak lurus sesuai diameter wheel-nya dan menyebabkan kupingan dari wheel bergesekan dengan rel.
Dalam penelitian ini, dilakukan analisis masalah dengan metode Fault Tree Analysis (FTA) untuk mengidentifikasi penyebab utama terjadinya friction trolley wheel. Metode FTA memberikan rekomendasi untuk menggantikan metode perbaikan manual yang memakan biaya dan waktu lebih tinggi dengan pembuatan desain roller guide. Desain roller guide ini mencakup beberapa komponen seperti bearing, bracket, pin, dan ring.
Analisis FTA mengevaluasi potensi penyebab friction trolley wheel yaitu perbedaan diameter roda, perbedaan putaran motor trolley (rpm), bearing yang aus, kerusakan pada gear, dan longgarnya diagonal rod . Pemilihan jenis bearing jatuh pada single row deep groove ball bearings dengan diameter cincin dalam 30 mm. Perhitungan lifetime bearing menunjukkan bearing dapat bertahan selama 43 tahun. Hasil simulasi desain roller guide memiliki displacement maximum 0,005976 mm menunjukkan perpindahan struktural sangat kecil, stress maximum 7,636 Mpa menunjukkan material masih dalam kondisi elastis, strain 0,0003039 menunjukkan material dapat kembali ke bentuk aslinya setelah beban dilepaskan. Hasil simulasi menunjukkan bahwa desain memiliki margin keamanan yang cukup.
=========================================================
The research aims to solve the friction trolley wheel problem that occurs on Rubber Tyred Gantry Crane (RTGC) type Konecranes at PT Terminal Petikemas Surabaya. Friction trolley wheel is a phenomenon where the trolley wheel moves not straight according to the diameter of the wheel and causes the wheel to rub against the rail.
In this study, the problem was analyzed using the Fault Tree Analysis (FTA) method to identify the main cause of the friction trolley wheel. The FTA method provides recommendations to replace the manual repair method which is costly and time consuming with the creation of a roller guide design. This roller guide design includes several components such as bearing, bracket, pin, and ring.
FTA analysis evaluates the potential causes of trolley wheel friction, namely differences in wheel diameter, differences in trolley motor rotation (rpm), worn bearings, gear damage, and loose diagonal rods. The selection of bearing types falls on single row deep groove ball bearings with an inner ring diameter of 30 mm. Bearing lifetime calculation shows the bearing can last for 43 years. The simulation results of the roller guide design have a displacement maximum displacement of 0.005976 mm, indicating a very small structural displacement very small, stress maximum 7.636 Mpa shows the material is still in elastic condition, strain 0.0003039 shows the material can return to its original shape after the load is released. The simulation results show that the design has sufficient safety margin.
