State of the art of small mining hoists
▪ Mining hoists are designed for hoisting tasks in vertical and
inclined mine shafts
▪ Their main intended purpose is the operation on
construction sites, providing access for personnel and
supply material to underground mining works
▪ The structure design of the hoists must be carried out in
compliance with the technical requirements and the mining
regulations for shaft and inclined hoisting systems

Mining hoists fabrication
▪ Development, layout design, documentation according to
the technical requirements and mining regulations for shaft
and inclined hoisting systems
▪ In-house fabrication of relevant structural steelwork
components
▪ Corrosion protection and coloring at the highest level
▪ Complete and professional assembly

Safety-related equipment
▪ Our mining hoists are equipped with:
▪ a depth indicator, which shows the current status of the
haulage means
▪ a speed monitoring system, which safely evaluates if the
maximum permitted speed is exceeded by more than 20%
▪ torque monitoring in case of the under cage transport of the
haulage means
▪ a 2-fold hanging rope control
▪ two braking devices: one brake acts as safety brake directly
onto the rope carrier and the second serves as a holding brake
▪ an emergency stop equipment, safety circuit

Auxiliary mining hoists
▪ They are installed in shafts and serve exclusively to rescue people from the
shaft in emergencies
▪ Rescuing cage with a capacity for 4 or 6 people
▪ SBN delivers its auxiliary hoisting system by using a modular chassis, which is
bolted to the reel base frame, advantages:
▪ faster transport
▪ simple relocation of the hoist
▪ the hoist is simply jacked up by the equipment available on the machine and braced to
the prepared foundation
▪ self-sufficient electrical power supply possible by carrying an emergency power generator
on the rear of the modular chassis
