The MX winches are available in various configurations.
The system is equipped with slip ring and connections through
which surface instrumentation can communicate with the probe.
A precision measuring wheel and rotary encoder are also included
to allow the amount of cable played out to be tracked. The cable
is automatically wrapped on the drum in even layers through the
level wind mechanism. The motor is controlled by a 110V (or 220V
depending on the model) four-quadrant motor speed controller that
allows the speed to remains constant with a varying load and prevents
overhauling with heavy loads.
Dynamic electronic brake is a standard item with a mechanical
(disc) brake optional.
