Abstract
The Crane is one of the heavy equipment in an industry. In the LAPAN Garut office, Crane is used for the rocket assembly process. The study examines the fatigue life prediction of Crane structures using the finite element method. Crane structure design uses Autodesk Inventor Professional 2017, while finite element analysis uses Ansys Workbench 2019 R1. Crane structure is subjected to a load of 10 tons with a fully-reserved type of loading. Fatigue life prediction using Gerber's mean stress theory. Crane structure material is Aluminum alloy. Simulation results show that the Crane structure has a minimum fatigue life of up to 1,971 x 10 6 cycles with a minimum safety factor of 1,106.

Summary
The Crane is one of the heavy equipment in an industry. In the LAPAN Garut office, Crane is used for the rocket assembly process. Crane digunakan untuk mengangkat beban berat dan memindahkannya dari satu tempat ke tempat yang lain [5]. Konstruksi struktur Crane dapat mengalami kegagalan karena berbagai faktor. Deformasi plastis karena beban berlebihan, kurangnya perawatan, korosi, dan fatik adalah beberapa penyebab kegagalan struktur Crane [7]. Penelitian ini bertujuan melakukan investigasi untuk mengetahui umur fatik struktur Crane kapasitas 10 Ton menggunakan Ansys Workbench 2019 R1.
