MERMAC S winches combine robustness with controllability. They are supplied

with variable speed, tension read-out and control via an integrated load cell. The

PLC on the winch controls the level wind, displays paid out length, speed and

a range of other information and alarms. It can also interface to other control

systems.

The electric driven level wind is equipped with safety features, including stop

switches at each end of the level wind to protect the cable. Optional PC software

offer computer control and fully automated profiling capabilities.

The winches can be adapted to suit various cable diameters through the PLC

controller and encoder and are also available with interchangeable drums.

Spare drums can be spooled with different cable sizes and swapped as needed

for fast and easy application changes.
