Lo pasti udah sering lihat excavator kerja pakai sistem hidrolik. Tapi pernah kepikiran gak… siapa yang pertama kali nemuin dan ngerakit teknologi ini? Dari Armstrong yang pakai air bertekanan di tahun 1882, sampai Kilgore yang bikin excavator full hidrolik pertama di 1897 — di sinilah awal mula sejarah excavator modern dimulai. Dan ternyata… eksperimen excavator listrik juga udah ada sejak 1914. — #alatberat #excavator #sejarah #operator #tambangbatubara
