Namun, proses pemompaan yang dilakukan secara berulang membutuhkan tenaga operator dan dapat menurunkan kenyamanan kerja, khususnya ketika ruang gerak terbatas. Penelitian ini bertujuan merancang dan membuat dongkrak hidrolik elektrik kapasitas nominal 3 ton dengan penggerak motor DC gearbox dan sistem pengaman limit switch, sehingga proses pengangkatan dapat dilakukan secara lebih praktis dengan tetap memperhatikan batas operasi alat.\nMetode penelitian menggunakan pendekatan rancang bangun yang meliputi perumusan kebutuhan, perancangan mekanik dan sistem kontrol, pemilihan komponen, pembuatan rangka, pemasangan motor dan transmisi sprocket-rantai, perakitan sistem limit switch, serta pengujian fungsi. Motor yang digunakan memiliki spesifikasi 24 V, 5 A, 100 rpm, dan torsi 11,46 Nm. Transmisi menggunakan sprocket 12 gigi sebagai penggerak dan 24 gigi sebagai sprocket yang digerakkan sehingga diperoleh rasio reduksi 2:1. Pengujian dilakukan pada beban 500 kg, 1.000 kg, dan 1.500 kg dengan parameter waktu pengangkatan, ketinggian angkat, arus motor, dan fungsi limit switch.\nKata Kunci: dongkrak hidrolik elektrik, motor DC gearbox, limit switch, kapasitas 3 ton, transmisi sprocket, keselamatan kerja","abstract_alt":null,"creators":[{"role":"author","family_name":"HARTONO","given_name":"FAJAR","orcid":null,"national_id":"2115161025"},{"role":"advisor","family_name":"Wijaya","given_name":"Wisnu","orcid":null,"national_id":"0420117101"}],"year":2022,"date_issued":"2022-08-16","publication":null,"volume":null,"issue":null,"pages":null,"publisher":null,"isbn":null,"issn":null,"doi":null,"official_url":null,"institution":"UNIVERSITAS SANGGA BUANA YPKP","id_number":null,"thesis_level":"bachelor","publication_status":"published","refereed":null,"keywords":["dongkrak hidrolik elektrik","motor DC gearbox","limit switch","kapasitas 3 ton","transmisi sprocket","keselamatan kerja"],"language":"id","subjects":[],"divisions":[{"code":"21201","name":"S1 Teknik Mesin","pddikti_code":"21201"}],"citation":"HARTONO, FAJAR (2022) RANCANG BANGUN DONGKRAK HIDROLIK ELEKTRIK KAPASITAS 3 TON DENGAN PENGGERAK MOTOR DC GEARBOX DAN SISTEM PENGAMAN LIMIT SWITCH.
