  About us



MX series
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.
