Abstract

The hydraulic system plays a vital role in supporting excavator performance by transmitting power through pressurized fluid to actuate the boom, arm, and bucket. However, fluid leakage can significantly reduce operational efficiency and performance. This study aims to analyze the hydraulic system performance of the Zhugimada mini excavator trainer unit before and after repair. Tests were conducted on three main parameters: silinder drift, silinder speed, and silinder pressure, under three load conditions zero capacity, struck capacity, and heaped capacity. The results show that leakage was caused by damage to the fittings on the arm and bucket silinders, the seal on the boom silinder, the valve connecting the tank and pump, and an electric motor speed exceeding the standard (1,491 rpm). The leakage impact was indicated by a decrease in silinder speed 1.41% for the boom, 1.34% for the arm, and 0.51% for the bucket and a 16.28% pressure drop in the boom under no-load conditions. After the repair, system performance improved significantly, with boom speed increasing by 0.92%–2.04% and arm speed by 0.82%–1.77%. The repair effectively addressed both internal and external leakage and improved the overall efficiency of the hydraulic system.

Abstract

The availability of practical facilities in mechanical engineering vocational education requires representative yet economical learning media. The development of a mini excavator demonstration tool by the Mechanical Engineering Department of Sekolah Vokasi Universitas Gadjah Mada (SV-UGM) is an effective alternative to support practical and research activities because it reflects the function and mechanism of an excavator with efficient costs and dimensions. This study analyzes the central body undercarriage design of the Zhuigimada mini excavator demonstration tool using the finite element method with the aid of Computer Aided Engineering tools. The material used is American Society for Testing and Materials (ASTM) A572 with a load of 19,620 N. The simulation results show a maximum von Mises stress of 21.69 MPa, a total displacement of 0.0133 mm, and a safety factor of 15.9. These values ​​indicate that the undercarriage design has good strength and stiffness against static loads produces an undercarriage design that is safe, efficient, and representative of the excavator work system.

Abstract

Program studi Teknik Pengelolaan dan Perawatan Alat Berat adalah program studi di perguruan tinggi yang fokus pada pengembangan keterampilan teknis untuk mengelola dan merawat alat berat. Program ini biasanya terdiri dari kombinasi kuliah teori, pelatihan praktis, dan magang di lapangan, dan bertujuan untuk mempersiapkan mahasiswa untuk menjadi teknisi yang terampil dan terlatih dalam mengelola dan merawat alat berat. Mahasiswa di program studi ini akan mempelajari dasar-dasar pemeliharaan, dan perbaikan alat berat. Mereka juga akan belajar tentang standar keselamatan dan regulasi yang berkaitan dengan pengoperasian alat berat, serta teknologi terbaru yang digunakan dalam industry pertambangan. Pembuatan komponen mekanisme swing digunakan untuk pembuatan pada alat peraga mini excavator yang nantinya akan dikembangkan untuk alat peraga pembelajaran sistem penggerak hidrolik. Tujuan akhir dari penelitian ini adalah merancang sistem swing dan menganalisis safety factor pada alat peraga mini excavator. Berdasarkan hasil analisis sistem swing pada alat peraga mini excavator dengan dilakukan menggunakan analisis statis, nilai safety factor pada komponen Spi 5,38, shaft motor swing 37,1 house bearing 5,65 lower structure 5,94 dan bracket motor swing 5,16 menunjukan diatas angka satu. Berarti beban yang diterima pada setiap komponen tidak melebihi batas yield strength, sehingga komponen yang telah dirancang dapat menahan beban sebesar 5300 N
