helical gear unit (referred to below simply as "gear unit") described in
these operating instructions has been developed for use as a hoist and luffing gear unit. Po-
tential applications for this series of gear units include, for example, conveyor systems and
lifting equipment.
The gear unit is available as a three or four-stage helical gear unit. These are designed for
horizontal mounting. The gear unit is also available for other mounting positions on request.
It can essentially be operated in both directions of rotation.

picted schematically as a solid shaft below. The direction of rotation arrows indicate the de-
pendency of the direction of rotation of the input and output shafts.
