First introduced for handling delicate oceanographic equipment, MacArtney MERMAC S electrically driven winches are advanced and robust systems suited for numerous general marine applications. MERMAC S winches are available with several purpose built features and options which make them ideal for use with side scan sonars, corers, CTD systems, towed vehicles and other instrument and equipment types. 

MacArtney MERMAC S winches combine reliability with controllability and are supplied with variable speed, tension read-out and control via an integrated load cell. A PLC on the winch controls the electrically driven level wind and transmits encoder and load cell data to a display showing winch speed, paid out cable length and alarms. The PLC can also interface to other control systems. Optional PC software offers fully automated profiling capabilities.

The winches can be adapted to suit various cable diameters and are also available with interchangeable drums. Spare drums can be spooled with different cable sizes and swapped as needed for swift change of winch application.

MacArtney MERMAC S winches often form part of complete vessel winch and handling solutions.
