The hoister gearbox is a special gearbox for mine hoisting equipment, wherein ZZ series products are hard-surface planetary gear reducer developed according to domestic and foreign market requirements and technology development trends. This includes a single-level (ZZD), two-level (ZZL) and three-level (ZZS) planetary gear structures, ZZDP and ZZLP planetary gear structures, for example, one-level parallel axis + one-level planetary structure (ZZDP), one-level parallel axis + two-level planetary structure (ZZLP) and other configurations. With comprehensive hoister gearbox category options, the gear box can not only meet the different spatial arrangement requirements of the whole unit but also has large transmission ratio, big output torque and good applicability.
