Abstract
The following pages detail the process of
selecting an appropriate hoisting system for a
mining operation.
The hoisting system is a crucial part of many
mining operations, specifically those underground
mines
that feature a vertical shaft entry for both
personnel and material haulage. There are
two main types of
hoisting systems, Drums and Friction. This
example will cover a Friction, or Koepe, hoisting
system.
Friction hoisting systems boast several
advantages over traditional drum hoists.
Newer models are
significantly less expensive than drum systems,
and thanks to multi-rope systems, can generally
lift
larger and heavier loads than traditional drum
hoists. Additionally, friction systems
feature smaller sizes
than drum systems for similar payloads and
applications, so delivery, installation, and even
maintenance
are less costly.
Friction hoists also have their downsides,
though. A balanced friction hoisting system
is unable to service
loading points at different elevations and are
better suited for shallower operations, less than
2,500 ft.
