MX Series - Semi-Portable Winches - Operations Manual

The MX winches are logging hoists capable of positioning a geophysical probe or other tools in a borehole. The MX winch line is comprised of the 4MXA-1000, 4MXB-1000 and 4MXC-1000. The system is equipped with slipring 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 an 120V or 230V when properly configured, AC input, four-quadrant regenerative drive motor speed controller that allows the speed to remain constant with varying loads and prevents overhauling with heavy loads. The winch is designed to be used in conjunction with the MGX II or Matrix console and a portable PC to achieve a complete logging system.
