KGHM Zanam haul trucks are designed to haul material from mine faces to handling points in mineral ore mines that are not subject to explosion risks.The trucks are equipped with a special push-out unloading system that removes output from the haulage box via removable slide wall and by movable box. The truck maintains its fixed height during unloading process, making it unnecessary to construct a higher gallery in handling points. The trucks are highly maneuverable, increasing their efficiency in narrow mine headings.The CB4-20TB 4×4 model truck is equipped with an additional drive system to improve handling.
