Cooperation of the Components
The winch is driven by a hydraulic motor (1). The hydraulic
motor is mounted to the frame of the winch which consists
of primary base (2), final base (3) and spacer bars (5).
The frame also supports the drum (4). The drum contains
the planetary gears which connect the motor drive shaft to
the drum.
The winch is equipped with a spring loaded and hydrau-
lically released holding brake. The holding brake is sepa-
rated from the drive of the winch by a freewheel.
The holding brake is kept closed when lifting a load. This
allows accurate load positioning.
When lowering a load the holding brake is hydraulically re-
leased. The additionally installed counter balance valve in-
side the motor allows controlled load lowering.
