MX Series Winches

Description

The MX Winch is a logging hoist 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 a 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 110V (or 220V depending on the model) four-quadrant motor speed controller that allows the speed to remain constant with a varying loads and prevents overhauling with heavy loads. It includes a mechanical brake.

The winch is designed to be used in conjunction with the MATRIX or BBox console and a portable PC to achieve a complete logging system.

NOTE: When using a DC inverter to power the winch, a true sine-wave inverter is required for smooth winch operation. Minimum power requirement for such an inverter is 600 watts, which should also allow operation of the logger.
