The cable winch neatly collects a 50-meter cable on the cable reel,
which is driven by motor. The cable with a plug can be reversed
through the lower part of the reel.
Main Functions
Collect the cable
Manual operation control box on the collect cable button, winch
collect the cable.
Using the remote control can also collect the cable.
Manual operation control box on the release cable button, winch
releases the cable.
Using the remote control can also release the cable.
Cable Length Monitoring
When the cable is fully wound, the winding action is stopped and
the display shows.
When there last 4 turns, the display and audio-visual alarm
respond;
When there last 1 turn, the shore-side safety circuit is
disconnected from the shore power supply, and the display and
audio-visual alarm respond.
Emergency stop
Pressing the emergency stop button cuts off the shore-side safety
circuit of the shore power supply and the power supply of the winch
control system.
Cable Automatic Management Function
During shore power use, the cable reel can detect the change in
cable tension in real time based on the position and tidal changes
of the vessel through the tension and control system. The cable
reel can automatically release or store the shore-to-ship
connection cable according to the change in cable tension value to
prevent the cable from being too tight or too loose.
Automatic cable release: When the vessel discharges cargo or the
tide rises, causing the vessel to rise, the cable tension
increases, and when the monitored cable tension exceeds the preset
value, the control system automatically controls the motor to
release a certain length of cable. When the monitored cable tension
value returns to normal, the control system gives the signal for
the motor to stop releasing cable, and the motor stops rotating and
simultaneously engages the brake.
Automatic cable retrieval: When the vessel loads cargo or the tide
falls, causing the vessel to descend, the cable tension decreases.
When the monitored cable tension is less than the pre-set value,
the control system automatically controls the motor to retrieve a
certain length of cable. When the monitored cable tension value
returns to normal, the control system gives the signal for the
motor to stop retrieving cable, and the motor stops rotating and
simultaneously engages the brake.
