Tag:, , , ,

dalam dunia pertambangan spesifikasi alat berat sangat diperhitungkan dalam perkembangan dan umur panjang dari tambang itu sendiri. Kemampuan dalam memperhitungkan alat alat tambang akan memberikan keuntungan dalam keuangan tambang. Pemakaian alat alat tambang disesuaikan dengan luas area tambang, banyaknya cadangan, kebutuhan produksi, dan kebutuhan kebutuhan lain yang disesuaikan dengan metode penambangan yang dilakukan.

Berikut beberapa spesifikasi alat berat yang digunakan dalam dunia pertambangan
