Mine Hoists: Types, Operation, Applications & Selection Guide

A mine hoist, also called a winder, is the critical equipment for raising and lowering personnel, ore, and supplies in vertical or inclined mine shafts. It forms the "lifeline" of underground mining, integrating mechanical, electrical, and hydraulic systems to ensure safe and efficient transportation.

How does a mine hoist work? Typically, it uses a motor to drive a winding drum, around which steel cables are wrapped. One end of the cable connects to a conveyance—such as a cage (for workers) or a skip (for ore)—while the other is fixed to the drum. When the motor runs, the drum rotates to wind or unwind the cable, lifting or lowering the conveyance. 

Safety systems like brakes activate instantly if speed exceeds limits or cables slack, preventing accidents. For example, in a small Zimbabwean gold mine, a single-drum electric hoist might lift 1-2 tons of ore per trip, with a signal bell system coordinating between surface and underground teams.

Mine hoists adapt to diverse scenarios. Small-scale mines (common in Zimbabwe) favor single-drum electric hoists (7.5kw-15kw) for shallow shafts (≤100 meters), as they’re compact and low-cost. Large deep shafts (≥500 meters) use double-drum friction hoists to handle heavy loads (10+ tons) and balance two conveyances. Remote mines without stable power opt for diesel single-drum hoists, which operate independently. Underground coal mines may add flame-proof components to hoists to avoid gas ignition.

Selection tips simplify decision-making: First, match hoist type to shaft depth—single-drum for shallow, double-drum for deep. Second, choose power based on electricity access: electric for grid-connected sites, diesel for remote areas. Third, check load capacity—calculate daily ore output (e.g., 50-ton/day mines need 2-3 ton hoists). Finally, prioritize safety features like fail-safe brakes and signal systems to meet local mining regulations.

As a professional mine hoist supplier, we tailor solutions to fit Zimbabwe’s mining landscape—from 7.5kw single-drum electric hoists for small gold mines to flame-proof double-drum systems for coal operations. All our equipment meets regional safety standards, with built-in fail-safe devices and compatible signal systems. 

Whether you need a ready-to-ship model or a customized hoist for deep shafts, we provide end-to-end support, from selection consulting to after-sales maintenance, helping your mining operations run safely and efficiently.
